    Vinyl liner - terminology

    Hi All. As expected - due to a job poorly done - my fiberglass pool paint is coming off and making my water milky white, less than two years after resurfacing. Since I do not intend to go through resurfacing again, I was thinking about using a liner. At the time I got an offer from a local...

    Liquidator allowing air in when pump is off

    Hi All, I have been using the LQ (with the 3/8) for a year now and love it. That said, I have been ignoring an issue with it and would appreciate your help fixing it. Since my LQ is higher than my IG pool, when the pump turns off water flows slowly from the LQ into the pool (via the outlet)...

    DIY solar heating

    Hi all, Since I live in a very hot and sunny area, a part of my recently completed project involved placing a shading net over the pool. Funnily enough the kids complain the water's too cold now. Never thought that could happen in our parts... :shock: So, I was thinking of starting a new...

    Using DE with a sand filter

    Hi All, Wasn't sure where to post this.... Basically everything is running smoothly with my pool, and the water is "fine". The only problem I am trying to control now is cloudiness that is the result of chalking (paint dust coming off into the water). I am keeping things under control by...

    Using Trichlor to raise CYA

    Hi Jason, Richard, I am not sure who the owner of "the pool calculator" is, but I thought that if anyone can help it's probably you. Since I use Trichlor to reach the stabilization of the pool, I think it would be great if the section on CYA also contained the very useful detail that CYA is...

    pH levels and FC

    Hi All, I have the following parameters established: 1. Shading net over the entire pool area 2. Opaque pool cover (at night and most of the time the pool is not in use) 3. A working Liquidator 4. 2 x 200gr Trichlor pucks already dissolved (approx. 15 ppm CYA according to the pool calculator)...

    Replacing the suction side pipe

    Hello All, I am about to replace my suction side pipe using rigid PVC, crossing the back yard from skimmer to pump and in effect making a 180 deg. turn. I have two possible ways of doing it and was wondering if there is a difference. The upside of the second option is less digging... but I...

    FAS/DPD reagent

    Apparently there is a distributor for LaMott test kits in Israel (finally!), and I am looking into it. I was wondering if anyone here used their kits (not the electronic, ColorQ ones) and can provide feedback. What I was not sure about was the FAS/DPD reagent. They seem to refer to a DPD #1...

    Installed The Liquidator

    Hi All. I've installed The Liquidator and I'm as happy as can be :whoot: I've seen many posts on this topic but thought I'd share my experience, just in case it may help someone else down the line. All in all, it was easy to install. One point worth mentioning: After replacing the 1/4"...

    Fiberglass pool resurfacing issue

    Hello all. It has been a long time since I've posted on the forum. I have recently drained my pool to clean it up after a long period of being inactive, and found what seems to be paint coming off. All I had to do was rub it with a piece of wet cloth. Dipping the cloth in a bucket of water...

    DPD in the pool

    I'm sorry - there is no forum for idiots so I used this one as my question is related to chemistry/health. I was clumsy enough to drop a DPD tablet into the pool :grrrr: Talk of my crusade to keep chemicals to a minimum in my pool! DUH! So, what's the impact? is it nothing or do I dump 15...

    Yet another "how do I keep my pH from going up"

    Hi All. I have to balance my pH every day or two. It goes from 7.2 to 7.5 in about a day and to ~7.7 the next day. Factors I am aware of that increase pH: 1. Bathers - the effect above occurs with or without bathers 2. Air leak in my piping - aeration as I understand it should not contribute...

    Pipe sizing

    Hello all. I am trying to deal with an air leak for the second time now. I managed to seal the first a while back but this one seems to be somewhere underground in the suction side pipe. Before going through digging up the pipe, I am considering buying a new pipe, installing it between the...

    Just when I thought I had everything under control...

    Hello, I was not sure which forum I should use. Since this is my first post on TFP I decided this would be most appropriate. Before I attempt to go into details, I figured I should open with the bottom line - my main questions. 1. Can CYA levels increase without using stabilized chlorine...
