Our new fiberglass pool is going in next week and they sent this today.
In order to maintain the 10yr surface warranty they want the chemistry different than what seems to be recommended here.
Not sure what to do. They want a monthly log and a pool store water test every 6 months to prove that we have maintained it to there requirements.

Welcome to TFP.

Lie and force the water to their specifications every 6 months for the pool store test.

Depends if you want to play their game for the next 10 years and how much effort you spend jumping through their arbitrary hoops.

CH of 150-200 is not a problem.

PH of 7.2-7.4 with TA of 80-120 ppm is difficult to maintain. Keep your TA at 80 and you can force pH down for a few hours to log the test.

FC of 1-3 PPM will give you constant algae battles. And they do not mention CYA. You can decide how you want to manage your pool.

+1. The industry standards are designed to sell chemicals. The more they have you chasing your tail, the more chemicals you need to do so.

A cheap, easy, clear pool is nowhere in their MO. Maybe your mom and pop pool store / service has the best intentions, but they follow the industry advice because a sales rep sounded smart about it.

Your pool is one of many combinations, each with its own parameters, but they push one size fits all advice.

Most anyone who offers a warranty will dig deep when possible to find an out. I have no qualms being dishonest back.

Thanks.
I I thought about doing the water test manipulation but for 10 years seems like a full-time job. Also wonder about the value of the warranty, I’ve heard that it’s pretty difficult to actually get one covered so I wonder if all the effort to follow their procedures even worth it.

I don’t think it is but I don’t buy warranties either.

We see two problems with fiberglass pools. First is cracks which are caused by installation errors and not water chemistry. The other is gel coat problems which we see regardless of how good the water chemistry is. Manufactuers have stepped up to fixing many of those problems under warranty and I have not heard them requiring lots of proof of water chemistry.

Have you checked with the pool manufacturer as to their warranty requirements?

Is your installation company making tougher requirements than the manufacturer?

And why is this being laid on you a week before installation instaed of before contract signing?

The warranty is just cut and pasted straight from the manufacturers warranty policy. Not sure why they waited until after the contract was signed to give the paperwork. Honestly, not sure if it would matter since I had no idea about pool chemistry until I started doing research after the fact.
