    Hayward AQR100 guide vs TFP for CYA and FC

    Pool installed Fall 2023 so not tons of experience yet, but I’ve read tons of the TFP docs, classes,…and been using the salt testing kit. I’ve been keeping CYA 60-90 and FC 4-6 but in doing some testing and trying to figure out what Hayward AQR100’s 24 hour swg output is (and still haven’t...

    Hey everyone, I'm a relatively new pool owner (9 months) and have a 14,500gal in-ground pool/spa. I've never had any issues with my chemical levels (tested weekly) until I recently started seeing mustard algae growth after a few birthday pool parties (in September and October). My kids also...

    How long should I expect stabilizer and chlorine to last in Texas heat?

    Hi, I live in TX and it’s been a crazy hot summer with consecutive 105+ degree days. I’m only on my 3rd yr off pool ownership and am confused as what to expect on how often I need to check and add stabilizer. Almost everywhere, you read that stabilizer NEVER breaks down and water must be...

    Accidentally swimming at very high FC levels

    We have a chlorine tank with an automated pump that runs on a timer. This afternoon, my son accidentally knocked the plug out and plugged it back into a regular socket instead of the one linked to the timer. Basically, the chlorine pump was running continuously for about five hours. I didn't...

    High CYA (90-100ppm) - keep chlorine up or drain?

    Hi all! I’m pretty anal regarding the pool (10000 gallons) and test daily, I’ve maintained a pretty perfect balance since opening but after a few heavy rains, heavy recent use (kids splashing) and an accidental overfill (forgot I left the faucet in when topping up!) the CYA diluted from 70ppm...

    Done with the advice of my pool builder and store! Can you help me know what to do?

    I am so glad this forum is here.... it's given me the confidence to start to try and get my head around my pool. The idea that my store and the builder gave me that its as easy as: 1. Dipping a strip in the water and looking for colour matches is an idea long gone!!! Those strips are illusions...

    CYA/Chlorine - Angry pool store guy

    I went to the pool store today with two objectives. I wanted to test my CYA and buy some acid. "Why don't you test the CYA yourself?," you ask. A few reasons actually... That particular test is the least fun one to do because it doesn't require my auto stirrer. I love my Taylor auto...

    Reasonable Chlorine Loss?

    I'm wondering how much is considered reasonable chlorine loss for a 24 hour period? Currently I'm losing about 6 FC every 24 hours with a CYA of 37 (also using 6 tabs left over from previous owner). My CC is .5 or less. Does this seem like alot of chlorine loss? How can I lessen it? Pool...

    Never had an issue. After opening this year can not get the chlorine to stabilize. Pool co sold us chemicals …I’ve used to no avail. (Chlorine, stabilizer etc).Directions say get chlorine up to range then add CYA. Another site says the opposite. I can’t get the chlorine up to a normal range. So...
