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...

It's time to close my in ground vinyl pool for the winter. However, there is a leak(s) most likely in the vinyl liner that has escaped detection. Several other leaks were found and patched but there remains more leaking. The liner is very old and needs replacing (+20 years), but my pool guy says...

That's what I thought

My pool guy recommended brass gate valves, not favoring Jandy's ? What say you?:confused:

This is the water level after 24 hours. After plugging all ports except the main drain the level dropped one inch.

I plugged both skimmer ports, and my return lines. After 24 hours, I lost about 1 inch of water (after plugging), and it appears to be holding at that level. So, with my skimmer lines plugged, I lost water but it apparently stopped at a certain point. I was fearful that my main drain was...

Thank you for the leak detection article. I have plugged the skimmers, and the return lines. Of course, I cannot get to the main drain as it is in the deep end. I have marked the water line on the face plate of the skimmer, and will watch this over the next 24 hours. I am fairly certain that...

I know that I have a suction side leak in my system. I believed that my manifold was leaking air at the t connections so I tried to use some pvc glue, and flex seal. Although it improved the volume of air in the pump basket it didnt completely solve my problem. In any event, I decided to turn my...

So is that $90.flat fee plus the parts?

Wonderful. Any idea what the average labor cost should be to change out my 3 ball valves with the Jandys ??

Thank you for taking the time to respond. I have heard that these are the way to go. Do you have specific experience with them?:cool:

I have a suction side air leak (could be more than one), that has stopped inconsistently with a water test. By that I mean, on any given time it may temporarily stop when using a water test, but the next time it will not. Despite the inconsistency, I have tried using pvc glue and flex seal to...

I likely will need to replace my 3 suction side valves (2 skimmers, and a main drain) as I think one or more are leaking air. Are Jandy valves the best way to go for long term reliability and maintenance ? Links to specific valves would be appreciated. :wave:

Makes good sense.

I'm lucky if I make it in the shallow end!! What do you mean by a weight belt?? What is "PB" If I might ask what is the other procedure? Again, always thank you !!:D

Passed overnight test again. Got my Barracuda running, although not perfectly. I will repeat my overnight test again tonight, and if its good, I will finish the SLAM and move on from there.
