Total Alkalinity (TA) acts as a “buffer” to prevent wild pH swings in a swimming pool. Simply put, it helps pH maintain its levels better.Understanding this relationship shows you how important it is to maintain your TA levels. This is where the total alkalinity calculator can help you out!This calculator will help you determine whether to increase or decrease TA levels. TA levels should be between 50 and 90 ppm, and anything lower than 50 ppm should be increased. Output of the Total Alkalinity CalculatorKnowing your pool’s volume is the most important part of using this calculator. If you don’t know it, use our pool volume calculator for a good estimate.Increasing total alkalinity levels will tell you how much baking soda to use. Yes, baking soda! It is a cheaper alternative to “alkalinity increasers” in the pool stores. As a matter of fact, the main ingredient of those increasers is sodium bicarbonate, aka baking soda.When decreasing TA, muriatic acid is the preferred choice. Please wear gloves, goggles, and a mask when handling muriatic acid as the fumes can be overwhelming and dangerous.Keep in mind that lowering TA with muriatic acid will also lower pH.Need a Refresher on Chemistry Readings?Download our handy guide for a quick and easy review of what chemistry parameters to test and which chemicals to use.Water Balance Isn’t Complicated!It isn’t overly difficult to keep your water balanced.

Health of swimmers. Bacteria and algae can cause illnesses ranging from mild skin irritation to more serious conditions like E. coli and hepatitis A. Cost-effective: Muriatic acid is an affordable and effective way to maintain your pool’s pH levels and prevent the growth of algae and bacteria. By using it regularly as part of your pool maintenance routine, you can save money on expensive treatments and repairs down the line. Protecting your pool from algae and bacteria growth is a crucial part of maintaining a healthy swimming environment. Using muriatic acid as part of your pool maintenance routine can help keep your water clean and clear, protect the health of swimmers, and save you money in the long run. Don’t let algae and bacteria take over your pool – make muriatic acid a regular part of your pool maintenance plan. How Does Muriatic Acid Affect Pool pH? Muriatic acid is a potent acid that can affect the pH level of your pool. When you add muriatic acid to your pool, it dissolves and releases hydrogen ions that lower the pH level. As the pH level drops, the water becomes more acidic, which can have negative effects on your pool and equipment. Low pH levels can cause corrosion, damage to pool surfaces and equipment, and skin and eye irritation. On the other hand, if your pool’s pH level is too high, it can lead to problems such as cloudy water, scaling, and reduced effectiveness of chlorine. Adding muriatic acid can help bring the pH level back to the optimal range of 7.2 to 7.8. It is important to note that the amount of muriatic acid needed to adjust the pH level will depend on the size of your pool and the starting pH level. A pool with a higher pH level will require more muriatic acid to bring it down to the desired range. While adding muriatic acid can help balance your pool’s pH level, it is important to do so carefully and follow proper safety precautions to avoid any accidents or damage to your pool and equipment. Lower the pH Levels of Your Pool Water If your pool’s pH levels are too high, adding muriatic acid can help bring them back into the appropriate range. When muriatic acid is added to pool water, it releases hydrogen ions that lower the pH level. However, it’s important to be cautious when adding muriatic acid. Too much can cause the pH level to drop too low, which can damage pool equipment and irritate swimmers’ eyes and skin. Before adding muriatic acid, it’s important to test the pool water to determine the current pH level. Then, use a pool calculator to determine the correct.

Groups (PGs) per Pool Calculator on the Red Hat Customer Portal for details. 3.4.2. Configuring Default PG Counts When you create a pool, you also create a number of placement groups for the pool. If you don’t specify the number of placement groups, Ceph will use the default value of 8, which is unacceptably low. You can increase the number of placement groups for a pool, but we recommend setting reasonable default values in your Ceph configuration file too. osd pool default pg num = 100osd pool default pgp num = 100 You need to set both the number of placement groups (total), and the number of placement groups used for objects (used in PG splitting). They should be equal. 3.4.3. PG Count for Small Clusters Small clusters don’t benefit from large numbers of placement groups. As the number of OSDs increase, choosing the right value for pg_num and pgp_num becomes more important because it has a significant influence on the behavior of the cluster as well as the durability of the data when something goes wrong (that is the probability that a catastrophic event leads to data loss). It is important to use the PG calculator with small clusters. 3.4.4. Calculating PG Count If you have more than 50 OSDs, we recommend approximately 50-100 placement groups per OSD to balance out resource usage, data durability and distribution. If you have less than 50 OSDs, choosing among the PG Count for Small Clusters is ideal. For a single pool of objects, you can use the following formula to get a baseline: (OSDs * 100) Total PGs = ------------ pool size Where pool size is either the number of replicas for replicated pools or the K+M sum for erasure coded pools (as returned by ceph osd erasure-code-profile get). You should then check if the result makes sense with the way you designed your Ceph cluster to maximize data durability, data distribution and minimize resource usage. The result should be rounded up to the nearest power of two. Rounding up is optional, but recommended for CRUSH to evenly balance the number of objects among placement groups. For a cluster with 200 OSDs and a pool size of 3 replicas, you would estimate your number of PGs as follows: (200 * 100) ----------- = 6667. Nearest power of 2: 8192 3 With 8192 placement groups distributed across 200 OSDs, that evaluates to approximately 41 placement groups per OSD. You also need to consider the number of pools you are likely to use in your cluster, since each pool will create placement groups too. Ensure that you have a reasonable maximum PG count. 3.4.5.

Sources. Adding borax to pool water can also help prevent scaling caused by high levels of calcium. The amount of borax needed to increase calcium hardness will depend on the current level of hardness and the desired level. Typically, 1 pound of borax will increase calcium hardness by about 7 ppm in 10,000 gallons of water. It’s important to note that while borax can increase calcium hardness, it is not a complete substitute for calcium chloride. If the calcium hardness is too low, calcium chloride should be used instead of or in addition to borax to raise the level to the appropriate range. How to calculate the amount of borax needed? Calculating the amount of borax required to raise the pH of a swimming pool involves some simple math. First, measure the volume of the pool in gallons or liters. This information can be obtained from the pool manufacturer or calculated using an online calculator. Next, determine the current pH level of the pool water using a pH testing kit. This will help you determine how much borax is needed to raise the pH to the desired level. Once you have this information, use a pool chemical calculator to determine the amount of borax needed. Remember to add the borax slowly to the pool water, near a return jet to ensure even distribution, and test the pH level frequently to avoid overcorrection. Borax calculator tool If you are unsure of how much borax to add to your pool, there are several borax calculator tools available online. These tools require you to enter the current pH, desired pH, pool volume, and the brand of borax you plan to use. The tool will then calculate the exact amount of borax needed to reach your desired pH level. When using a borax calculator tool, it is important to make sure you have accurate measurements of your pool volume and current pH level. Using incorrect measurements can result in over or under-dosing the borax, which can have adverse effects on the pool water chemistry. Most borax calculator tools are user-friendly and can be found for free online. However, it is important to double-check the calculations and recommendations provided by the tool to ensure accuracy.

In this article, we will focus on the two main ones: the pool chemistry itself, and your wallet. Related: Six Bad Habits in Pool ServicePool chemistry consequences of not measuring chemicalsAdding chemicals correctly to a swimming pool requires knowing a few things:The correct volume of the pool (gallons, liters, etc.)The current water chemistry of the swimming pool, and its LSI balance value.The correct dose of the chemical you need to add (the proper amount of a chemical to make the desired adjustment)How to actually add the chemical to water correctly (like sodium bicarbonate or muriatic acid)The one thing missing from that list of bullet points is the focus of this article. Measuring. Once you know the pool volume and the current chemistry of the pool, you can use a reference chart (or the Free Orenda App) to find an accurate dose for the chemical you need to add to the water. Measuring that specific amount of chemical is perhaps the most self-explanatory practice, yet it is widely ignored. Instead, pool owners and operators tend to 'eyeball it' or guess. And sure, with something like liquid chlorine, a few extra ounces won't make a huge difference in a backyard pool. But a few extra ounces of muriatic acid can. And many people are unaware of how significant the difference is.Take Soda Ash (sodium carbonate) as another example. Soda Ash is about 1200 times more basic than sodium bicarb. It has between an 11.3 and 11.8 pH when added to water, as opposed to sodium bicarb which has 8.3 to 8.6 pH. If not measured and added correctly, Soda Ash is likely to cloud up the pool before your eyes. While people can get somewhat careless and estimate how much bicarb is needed for a swimming pool, Soda Ash should be measured precisely. Otherwise, your pool will cloud up and cause a mess.Dry vs. Liquid measurementsThere is one important distinction worth mentioning here. We also have this as a warning on the dosing results page of the Orenda Calculator™. Dry chemicals are measured by weight, whereas liquids are measured by volume.

Can You Raise Alkalinity and Lower pH at the Same Time?What’s the Difference Between pH and Alkalinity?What Happens to pH When You Raise Alkalinity?Recommended Products:Can You Raise Alkalinity and Lower pH at the Same Time?It is possible to raise alkalinity and lower pH in a pool but you need to do it in steps. You must first raise the Total Alkalinity (TA) level, using Baking Soda, so as to get it within the 80 – 120 ppm range. The next step is to lower pH by adding Muriatic Acid or Sodium Bisulfate (aka Dry Acid).Maintaining the pool chemistry in perfect balance is the key to a crystal clear and bacteria free pool. Of the different variables involved, getting the pH and total alkalinity right can be quite challenging, even for pool pro. In practice this is not as simple as it sounds. Addition of muriatic acid or sodium bisulfate will not only lower pH but will also lower total alkalinity. So you may actually have to repeat the steps of adding baking soda and sodium bisulfate till you get both in the desired range.You can use my Pool Baking Soda Calculator to determine the dosage for your pool.PRO TIP 1: In the first step aim to get total alkalinity at the higher end of the 80 – 120 ppm range.PRO TIP 2: Run your pump on “circulate: setting for a couple of hours after adding the chemicals. Wait for at least 6 hours for complete dispersion before testing pH and TA.All this waltzing around becomes necessary because pH and TA are similar but not the same. The level of one affects the level of another but not in an exact linear fashion. So the question is……..As an Amazon Associate, I earn from qualifying purchases.Click on the image below to reach the page with all the Necessary Pool Chemicals.What’s the Difference Between pH and Alkalinity?To begin with, pH is a measure of the acidity or the alkalinity of the pool water, whereas total alkalinity (TA) is a measure of the amount of alkaline particles dissolved in the water. The alkalinity of water is its ability to neutralize acids. Alkalinity therefore acts, and is known as a pH buffer!A logarithmic scale from 0 to 14 is used to measure pH. Distilled water at a pH of 7 is considered neutral. A pH level below 7 indicates that your pool water is acidic,
