Thanks so much! That's what I was looking for! No. Buying new sand for another pool Thanks! That's helpful

Hi, I remember reading once about recommended sand type to use but I can't find it now. Any TFP member available to help me find it?

Hi, Which cover did you end up getting? I also just got quoted like 10K for a Looploc

This is a pricy machine! Can anyone else weigh in? Thanks so much for all replies Quantum and Warrior are the same and the Quantum is $300 more just because? We have a pool in Brooklyn! Problem is that because there are not many pools here I can't find any good pool service company to fix a...

Hi All! I am looking to buy a robot for the first time. Pool is approx 28" X 40" odd shaped pool (picture attached). I have lots of debris from trees I have looked at the Dolphin Quantum, Dolphin Premier, Dolphin S200, Polaris 9550, and Pentair Warrior SE Which one would be doing the best job...

Saw that so why does it say on bottle "this product is not a sanitizer? In pool math how do I calculate effects of adding this product. I believe regular dichlor is 99%

I bought it to do dichlor then bleach method. Was delivered today. Active ingredient, Sodium Dichloro-S-Triazinetrione 58.2%. Is this dichlor? Why does it say on bottle "this product is not a sanitizer?

After skimming through this post I got the feeling that for SWG's the CYA should be higher?

Saw that for indoor pools. Same with SWG?

So I read this and I see recommended CYA level for outdoor pool is 70-80 Same for indoor spa?

You are right and that's why a woman's mikvah is much easier to maintain. The issue is with a mikvah men use What would the CYA help in an indoor mikvah?

It’s definitely not equal to a spa. Was just the best example I was able to think of. Another thing that differentiates it from a spa is that due to the high bather load the water needs to be balanced/adjusted every day and if it’s being done manually and you wait at least half an hour between...

You can soak in it as long as you’d like to although typically people don’t spend more than 10 minutes inside. The filter can be ON. What you said would be true if there are only a few users but a Mikvah with high bather load there’s a demand for adding sanitizer while filter is OFF or you have...

Please CMIIW but with chorine/bromine it’s not so accurate to figure out dosage by measuring how much sanitizer is in the water after introducing it into the water as you can’t know how how much was depleted by organic waste etc. Re CC. In a Mikvah/spa that’s being used by approx 30 people in...
