    Tests not matching

    I’ve had my pool for 5 years with minimal issues. Now I can’t seem to trust any test as they all give me different readings. Specifically with the CYA, calcium, and alkalinity. I have new reagents in my tf-100 and that’s what I’ve been using for the past 5 years. I replaced half the water in...

    Slow growing green algae despite good numbers!

    Hi all, I have been fighting green algae accumulation and proper LSI balance in our pool all summer without success. Any help would be appreciated! The pool water is not green, but green algae is slowly growing on the pool sides despite good FC levels and slamming. I started in mid July...

    When to stop "acid addition & aeration" cycle to reduce TA

    More corrosion questions from a skeptical SWG wannabe convert

    Hi all, After adding solar and keeping our pool warmer this summer, I'm more seriously considering adding a SWG as the chlorine demand is getting more intense. The general opinion here at TFP seems to be in favor of SWGs, and that the risk of corrosion is low. Many seemingly informed sites...

    Advice needed: plumbing in a DIY ground solar system and later a SWG.

    We bought our home with pool last year (1st time pool owner here) and wow what a challenging yet fun filled learning curve it's been. Due to lots of shade and no heat source installed , last fall I quickly began researching options. Limited funds led me to try connecting several longgggg black...

    SWG confusion

    I am new to pools, and am rather confused about our Intex Salt Water Generator and Sand Filter system. I’m hoping someone can explain in a way I can understand. So we followed all the instructions for set up (a week + into it now). It is the Intex Ultra Rectangular 12x24. The filter and SWG...

    Contemplating getting a Pentair Intellichlor

    I'm wanting to have a better understanding of how SWGs work. My understanding is that they kind of work like a puck system (minus the increase in CYA and having to buy pucks - you buy salt instead). Is that close to accurate? Here is my current setup (see images) - I have a full Pentair system...

    Converting inoperative pool to SWG

    We are in the process of purchasing a house with a pool and just had the pool inspection completed. The existing heater and pump are old and non-functional, so I was wondering if now is the time to convert it to an SWG. We are hoping to have the sellers pay for at least half the cost. I assume...

    Low salt reading

    So my aquarite is giving me a reading of 2300. I had the water tested and it's really at 4000. Before opening up this season I replaced my thermistor because my readings were off last season. New thermistor and still bad inaccurate readings. In 8 years I've replaced the thermistor twice...

    High salt leads to better opening?

    Hey TFPers, I have a 20k gallon fiberglass with salt water generator. Late last year the salt cell broke and read low salt so we kept adding salt (even though the pool did not need salt). We eventually figured out the problem after buying an electronic salt reader. We got everything back to...

    Intex CS8110 SWG cell replacement

    Getting started with a SWG

    Hi everyone! I just set up an Intex 15' diameter, 4' tall pool and filled it with water.

I have a couple of questions: 1) Should I add...

    Question on stabilizer before I slam

    Hey y'all! I've had a pool for a season, but our small town pool supply store just went out of business, so I found TFP and am attempting to maintain it myself this year. I got a Taylor testing kit and got some numbers. My FC was 1, CC was 5.5, PH was 8.4, TA was 130, CH was 180, CYA was 0...

    Hi All, Hope everyone is doing well through COVID-19. I just opened my pool and converted to salt. I have a Circupool RJ45 +. I balance my water before adding the salt and then dumbed 14 bags (560 lbs) into the pool. I waited 24 hours and then turned the SWG on. My initial reading was 3500...

    Brand New Pool Install

    I have an new pool, roughly 5212 gallons with a SWG (Intex) My question is do I need to create my own FC first before starting up the SWG so it doesn't have to work as hard? or get my CYA levels to 70 min (recommended for salt based on other threads I have found) and start the SWG according to...

    NaCl Upward Drift?

    I started my opening process about a month ago. After the rainiest winter on record, my salt levels (along with CYA and CH) were rock bottom. I got the salt up to 3000 ppm, and left it there. Well in the month since, we’ve had two rain events of 5”+ (each) that have required me to pump out...

    SWG High Flow Rate Limit?

    I am currently converting from Clorox to a Circupool RJ+ SWG system. I have seen on the Pentair SWGs that there is a maximum flowrate through their cell, but I don't find anything on maximum flowrate of a Circupool. Does anyone know if there is a maximum flowrate for a Circupool RJ45+ cell?

    Proper way to turn off SWG

    When you turn off the SWG to add salt, what is the proper way to turn it off and then back on? I put mine in Service mode and then unplugged it and reversed this for turning it back on. Is that correct?
