Thank you. I will add very slowly, and in small amounts.

My tests indicated a calcium hardness of 75 ppm, and my liner and heater manufactureres recommed a minum of 200 ppm. I purchased a 50 lb bag of calcium chloride, ice melt pellets, at Home Depot, and proceeded to attempt to dissolve then in warm water. The water became fairly hot after mixing in...

You are correct, my mistake on the math ! Thank you

I understand that low calcium levels are not an issue for vinyl pools. My test indicated a score of 100 ppm, and Raypak recommends a level of 200 to 400. Pool math indicated adding a great deal of calcium chloride, about 577 ounces to bring the level up to 250 ppm. That is close to 100 pounds of...

After adding the dry acid according to the bottle instructions, my PH came down to right where I want it at 7.4. However, the total alkalinity remained at 150. I inserted these numbers into "pool math", and no recommendations were given to bring the TA down. Yes? Or am I doing something wrong ...

Thanks for the tip. I have used about 50 oz. of the Clorox brand of dry acid, following their instructions. I diluted the 50 oz., in water before distribution in the pool. Most likely, I will have to add more, so I will switch to liquid muriatic acid. Is their a certain type or strength o buy...

I am talking about the Polaris P825 which is an electric robotic vacuum. I used my pool blaster today for vacuuming about a half dozen specific areas of debris build-up. The blaster was great for that. However, I can't see using that for the entire pool, hence the potential need for a robot ...

I have a brand new liner, and want to discuss routine vacuuming maintenance. I purchased a pool blaster and it did a great job at spot vacuuming highly visible but limited debris areas. Since, I have a rather large pool, 40X20, using the blaster on the entire pool would be cumbersome. Assuming...

I measured my TA and it came out to 150, and the PH was at 8.2. The pool math calculations, predicated on 26000 gallons and the aforestated numbers recommended adding 103 oz of dry acid to bring my PH down to 7.4. The Clorox brand dry acid (sodium bisulfate) bottle instructions recommends 50 oz...

I am no expert but can only provide you with my experience. I have a large in ground with two skimmers, and a main drain. I have always had air leaks, and could never find the source of the leak(s). My pump basket would show air bubbles, and the extent of the air would vary from day to day. I...

I have closed the pool and have decided to keep the water filled as best as possible over the winter. I have a hose attached to my basement laundry tub and will be able to reach the pool. The leak up to now has not been that great, about 3/8 inch per day. Hopefully I will be able to maintain a...

I am unable to get anyone out here to fix the leak at this time of the year. What choice do I have?

The water is still leaking. It is slightly below the skimmer level, and leaking. I am not adding water. Today an experienced pool guy told me that vermiculite bottom pools with vinyl liners will not pop out of the ground as the vermiculite is water permeable. Thus water pressure will be relieved...

I can't get anyone to fix the leak now as the water is too cold for a diver. I don't have a heater, and the water temp is in the 60's. I would replace the liner but they tell me that they need warmer weather for that. So I am stuck. I'm not sure or understanding the function of a tarp? Is that...

I do not know where the leak stops. I have been letting it sit w/out running the pump but I think it's still leaking. At this point I have some algae building up so I shocked the pool and am running the filter. However, the water is below the skimmer levels so only my main drain is operating. I...
