    can't understand inconsistent readings

    I have a Goldline Aquarite SWG, T-15 cell. I am getting very inconsistent readings on the display. It says the salt level is 2200, then it will say 3500 the next day. This is instant and average. The display keeps toggling back to metric, and the cell to T-5, then I use the Supercholrinate...

    losing suction with vacuum hose - can't solve this mystery

    I can't figure this out, and am hoping someone can help. I have a 30,000 gallon, inground pool, 2 skimmers, one main drain. When I vacuum, I attach the hose to a plate, put the plate in one skimmer, then shut off the other skimmer and main drain (or almost shut off, just a trickle). I've done...

    Hayward Sharkvac belt replacement

    I have a Sharkvac RC9740. Not XL. The tank tread belt that drives the wheels broke, and I want to replace it. I ordered a new belt from Amazon. I cannot find any directions or YouTube videos on how to do this. Has anyone done this before, and could give a few tips or hints? Also, a secondary...

    Aquarite - replaced varistor - now stopped again

    I have an Aquarite SWG. I've replaced the mother board twice in 8 years. It went out again this summer - no power light but the display works. This time, I bought the varistor or inrush current limited from Digikey and soldered it on. This worked -- the power light came back on and it...

    Modify the OTO chlorine test -- will this work?

    I know I should have a better test kit, but I don't right now. I am trying to SLAM my pool, and using the chlorine test that uses 5 drops of the yellow reagent. I thought that I read that you could dilute your pool water with distilled water, 50/50, and then double the result. This makes...

    Hayward Sharkvac - Shark Vac - does it learn your pool shape

    I recently bought a Hayward Shark Vac. I believe one of its advantages is that it lears the shape of your pool, and then becomes more efficienct with coverage. My question is, is this learning cumulative? A cleaning cycle is 2 hours -- does it learn during this 2 hours, and get more...

    Blowing out the skimmers on IGP -- blowing from the pump

    I plan to close my IGP myself for the first time this year, after watching the pros do it the last couple years. I plan to hook my rather large Craftsman air compressor up to the drain hole on the pump, and push the water out the returns and skimmers, then blow air through the main drain and...

    bug spray or weed killer in pool -- water is now cloudy

    My water has been perfectly crystal clear. Yesterday, I sprayed Weed-B-Gone on my lawn, and also a lot of Spectracide insecticide. I used a broadcast sprayer hooked up to a garden hose. Later that day and night, and now this morning, my pool is cloudy. Its hard to make out the main drain. I...

    Aquarite -- cheap cap to fit cell for cleaning

    Has anyone found a cheap cap to fit the Aquarite cell, for cleaning purposes? I see a cleaning stand sold on line for $30 or $40. I was hoping to get a simple PVC screw-on cap at Home Depot. However, it is an odd size -- its not 1.5 inch or 2 inch. I can't find anything that fits it. Does...

    Kreepy Krauly - Thruster backup valve -- how to attach

    I bought a Thruster backup valve for my Kreepy, since it always gets caught on the shallow end steps. However, I bought it used on craigslist and don't have directions. I can't find them anywhere on the web. Does anyone have a pdf of the directions. I am most interested in how to attach it...

    Aquarite - Salt reading is 0 - water temp is up

    I have a 30,000 gallon, vinyl liner in-ground pool, with an Aquarite SWG. Its worked fine for the last 3 summers. I just opened last weekend, so had to add salt, CYA, etc. My salt was at 1300 (test strips), I added 320 lbs, so I know there's salt in there. I've brushed it around, and there's...

    Poolskim -- experience in a larger pool

    I've seen some posts on the Poolskim, and most people seem pleased with it. My concern is this: it seems like it would work in a smaller pool, but less so in a big pool. I have an L-shaped pool, 40 feet long and 24 wide. 30,000 gallons. I have two skimmers, one main drain, and 6 return jets...

    Can I close off some of my returns?

    I have an inground pool, 30,000 gallons. There are two "step jets" (returns in the steps out of the shallow end) and four other returns. I think I would get better circulation if I closed the step jets and just used the four other returns. (The builder said the returns on the steps is to help...

    Air Lock Skimmers and Returns -- why not?

    I understand the concept of airlocking the main drain. You can't plug it, so blow air until it bubbles, then close the valve at the equipment pad. Its like putting your finger over the top of a straw. On the other hand, we blow out the returns and skimmers, then plug them, so water cannot go...

    Inexpensive CYA test kit

    Just discovered this board! I've got a 3 year old pool, and learned a ton from the old pool forum. My question concerns testing for CYA. The 3 local pool stores near me give wildly different results, and only occasionally correspond to my calculated number. I want my own CYA test kit. The...
