Always follow safety precautions and the manufacturer's directions when working with concentrated solutions of bleach (sodium hypochlorite). For water destined for drinking, it is always important to provide a 30-min contact time after adding the chlorine and mixing, then to test the water to ensure the desired residual has been achieved. Salt; pH; Total Alkalinity; Cyanuric Acid; Hardness; Phosphates; Before adding salt, test your pool water for the current level of salt. You always want the FC level to be at least as high as the target level. Login / Join Created with Lunacy ... We don't really have a set calculation because everything will depend on the manufacturer of the type of shock that you'll be using, refer to the packaging for more precise instructions on how much to use. Your pool needs a minimum concentration of 1ppm and up to a max of 4ppm of chlorine, so you don’t have to worry about stinging eyes or excessive bacteria growth! High pH can lead to calcium scaling. Salt can be added using solar salt, sold for use in water softeners (sodium chloride). No problem, just enter the … Its responsibilities include sanitization, disinfection and oxidation. All volumes on the same horizontal line (row) are equal. As an approximation you can multiply TH by two thirds to get a rough estimate of CH. Trichlor and dichlor also add CYA and lower pH. For example: To achieve 5 mg/L chlorine in a 1000 litre tank add approximately 8 grams of 65% calcium hypochlorite. Table I-4 shows the equivalence between common fractions and decimals. If pH is too low, the water can be corrosive to pool equipment. This calculator can be used to adjust the chlorine concentration of water to disinfect it for drinking and also for other applications. Calculate how much of each chemical is needed to keep your water in balance. If your measuring device is not as precise as the number you come up with, it is generally advisable to round the calculated number up to ensure you provide at least the dose you intended to provide. Cyanuric acid, often called stabilizer or sometimes conditioner, both protects FC from sunlight and lowers the effective strength of the FC. deep end ft. please enter a value. The chlorine levels should be maintained at a level of 1 part per million (ppm) to 3 ppm at all time since is the safest level for human usage. This can be mitigated by lowering TA. If you have black algae it is particularly important that you vigorously brush the algae as frequently as possible. Indoor pools should have a chlorine level of 2–3 mg/L and must not use cyanuric acid. Convenience Options. You should keep your pool or spa Free Available Chlorine (FAC) level between 2.0 & 10.0 parts per million (PPM). 1. Adding powdered chlorine (calcium hypochlorite) or liquid chlorine (sodium hypochlorite) to water raises the pH, so careful additions of an acid are necessary to maintain the pool water at a pH between 7.3 and 7.5. info@bestpoolsupplies.com.au. Potassium monopersulfate (a common non-chlorine shock) will often show up on tests as CC. Product Label Chemical Dosage Some labels will have directions on how much chemical to add for a given quantity of water. These are becoming increasingly popular in Australia. rights reserved © Copyright 2000 -. You increase CH with calcium chloride, sold as a deicer and by pool stores, or calcium chloride dihydrate, sold by pools stores for increasing calcium. ATA or CTA - Adjusted or Corrected Total Alkalinity. Quickly get answers for how much chlorine to add to the pool or how to balance the pool ph … The LSI, Langelier Saturation Index, is a very similar but slightly less accurate measure. Chemistry. pH indicates how acidic or basic the water is. However, when I used the chart at the back of the Taylor test kit (and confirmed with the Pool Calculator) it only suggests adding about 1/4 gallon of chlorine. The volume of my pool/spa is. This calculator can be used to adjust the chlorine … This level will typically around 3,000, but different models vary. A plaster pool should have CH levels between 250 and 350 if possible. 5 x 10 = 8.3 mL of concentrated hypochlorite solution made from 1 level tsp HTH in calculated pool volume. Have any of you come across discrepancies like this? Free Shipping Australia Wide. TA contributes to the CSI which indicates the tendency for plaster damage or calcium scaling. It is most efficient to raise the FC level in the evening, since none will be lost to sunlight until the next morning. Our suggestions for a season’s supply are based on past experience in a 4 month season, with average weather. I want my Cyanuric Acid level to be. Pool Math performs all the calculations you … If you have a SWG, or if you commonly run water features such as a spa, waterfall, or fountain, keep TA on the low side, between 60 and 80. If you have a SWG or very high levels of direct sunlight, CYA is typically kept between 60 and 80. Conversion factors Lower (Neutralize) Chlorine Level. FC is commonly lowest in the evening after sunlight has been reducing it all day. The only practical way to lower CYA is to replace water. oblong. For a SWG, check the manual for the correct salt level for your unit. If your water starts looking dull or just slightly cloudy try using a higher FC target. To estimate how much of each chemical you will need, the first step is to determine the volume of your pool. Tables I-1 and I-2 provide volumes in drops (dp), milliliters (mL), teaspoons (tsp), tablespoons (tbls), cups (cp), liters (L), and gallons (gal) of liquid bleach, dry calcium hypochlorite (HTH), and a concentrated calcium hypochlorite solution that, when added to the indicated volume of water, will provide the approximate chlorine dose indicated. These levels are less then one tenth of the salt level in ocean water, which has around 35,000 ppm of salt. Pools with plaster surfaces should factor their CSI into the preferred TA level decision. The ideal TA level depends on several factors. Just enter the dimensions of your pool (in metres) and the Calculator will work out the approximate volume of your pool (A metric converter is provided to aid you with this). Most chlorinator models require 3500ppm - 7000ppm (0.35% - 0.7%). You increase borates by adding borax and acid, or by adding boric acid. Raise Total Alkalinity. AquaChek’s easy to use calculators take the guesswork out of balancing your pool or spa. A kind of sensor that reacts to disinfecting chlorine levels which is used in some systems that automatically feed chlorine into the pool based on the sensor's measurement of the current chlorine level in the pool. This will kill anything that might be living in your water and to speed the breakdown of CC. How much higher depends on your CYA level, the amount of sunlight that falls on the pool, and how much the pool is used. If you are using an ORP controller, keep CYA below 50. proceeding down the column with “drop” at the top, there are 15 dp in a mL, 74 dp in a tsp, 3550 dp in a cp, and a whopping 56,775 dp in a gal. CSI is most sensitive to changes in pH. The amount of chlorine required to be added to your water supply would depend on the quality of the water. (1) For Liquid Bleach (~ 5% available chlorine): rectangular. Keep swimming in your TroubleFreePool with Pool Math. Higher CYA levels bind up more of the FC, requiring higher FC levels to get the same disinfecting chlorine level. Specific gravity is incorporated as part of the solution strength (% w/v). PoolMath makes swimming pool care, maintenance and management easy by tracking chlorine, pH, alkalinity and other levels to help calculate how much salt, bleach and other chemicals to add. Please note the above calculations are only estimates. Our suggestions for a season’s supply are based on past experience in a 4 month season, with average weather. If you have ever used stabilizer or dichlor or trichlor your CYA level won't really be zero. All you need to do is plug in your pool volume (which you calculated above) and your current salt levels (which you tested for) and hit “calculate.” I already plugged in the ideal salt level of 3,200 ppm, but if you feel strongly that you want it to be lower or higher, you can adjust it as needed. Desired increase in calcium hardness. If you don’t know your pool’s volume, view our pool volume calculator for assistance. Equation 1A: Average Dose - Chlorine dosage (mg/L) measured as Cl2: Eq. Solid stabilizer can take up to a week to dissolve, so don't retest your CYA level for a week after adding some. Otherwise levels between 70 and 90 are good. CC indicates that there is something in the water that the FC is in the process of breaking down. The normal FC target is given as a range because different pools require different FC levels. Water Chemistry Calculator. Since pets should always be trained to not drink pool water, this shouldn't be a problem. Having sparkling, clean water is every pool owner’s dream. FC is raised with bleach, liquid chlorine, liquid shock, trichlor tablets/pucks/sticks, dichlor powder, cal-hypo powder/capsules, or lithium hypochlorite. See how much you can save with our other pool product calcutors. Adding of . The ratio of calcium to magnesium varies. Be careful if your CYA level is really and truly zero. HOW TO USE THE TABLES: 1. Raise Chlorine Level. 9-11 Centennial Cct Byron Bay NSW 2481 Phone. I-4. Buffering means you need to use a larger quantity of a chemical to change the pH.
