Hi all
New pool owner.
Been dealing with a persistent mustard algae issue and mistakenly followed advice from pool shop on how to treat it.
I had brought my pool to shock levels consistent with guidelines here (but not quite to mustard shock levels) - I hadn’t seen this at the time.
I seemed to have the algae at bay with just some minor spot re-occurrence in the same locations. On advice of the pool shop I decided to try and completely eradicate with the use of a quat/copper algaecide (50g/L organo copper complex + 100g/L benzalkonium chloride ammonium quaternary).
I ran my SWG at 100% for the following two days and my pool shop results were
10 FC
0.9 CC
80 TA
7.5 pH
CH 220
Salt 3500
CYA 27
This is the first time I have seen a CC reading since owning.
Reading up on the action of ammonia based algaecides - they react with free chlorine to form chloroamines.
From what I have read from other similar algaecides - this affect is temporary but I have been 3 days since the treatment?
Should I continue to wait or do I treat this ASAP?
My understanding is preferred option is super chlorination to break point is one option or non chlorine based shock (Potassium peroxymonosulfate).
I ask because I either let my FC drop by stopping SWG for a day or so - or superchlorinate now as it will only be a relatively minor FC increase?
Noting - the CC to FC is already above the 10x ratio I have read about?? Which makes me wonder if this is indeed ‘temporary’?
Thanks in advance!
