After years of fighting High CYA levels, my CYA is 30 and FC is 3 when I tested, PH 7.6. Pool is crystal clear. I have the test and refills but have not ran a full set other than chlorine and PH, and cya today. Trying to keep it simple.
Other than buying Chlorine and O-rings for valves I have not been to pool store this year nor have I done anything other than chlorine to the pool since opening. I can chlorine for less but I choose to support the local business with chlorine purchase because they are there for me when I need them.
I was thinking of raising my CYA to 40. Would that be advisable? What is a valid source of stabilizer? Is liquid stabilizer better?
Honestly I have not added since I opened my pool years ago and it was over 100 for years. I don't remember other than adding it to skimmer. I no longer use pucks, which also allowed me to drop the cya over time as I dumped water.
Also, I don't use Shock packs, last time I did my water turned green before my eyes, it was like a reaction to metals or something. I have city water. So I shock with liquid chlorine or use the non chlorine shock occasionally.
The reason I was thinking this was to maybe prolong the life of the chlorine? When I go to pool store and test water they push for CYA to get to 100. When CYA was that high I was fighting algae constantly and tinted water. Plus I ran the chlorine high.
I have been adding 36 oz 12.5% daily and my FC is usually 2-2.5 when I check at dusk. I have not tried an overnight test, I assume the dissipation is normal as we have had lots of sun. Also heavy rains.
In a way I kinda don't want to do much. Folks that come over cannot believe I use bleach basically.
