So we are just trying the product Black Alae Killer (Leslies) step 4, for the black algae pool we have.... long time fighting and controlling it...
The pool owner brought this from the US (we are in Mexico, in Baja) together with the Fresh and Clear step 3 Oxidizing shock...
Don't really know if this will work but we are running out of options.
So today this were the basic readings:
It is a SWG at 100% for now and, maybe a mistake, but has helped a little, we have added a couple of chlorine tablets too.
FC: 8 (trying to have it high to algae doesn't multiply that fast)
So we have been trying to find out what to do after the treatment as the product label or webpage doesn't explain in detail.
It says to apply one part of the black algae product for 9 of water and apply 12 oz for every 10,000 gallons. It is a 13,000 gallon pool so we added 12-14 oz and about 120 oz. of water.
We poured it then into the pool but many questions are left:
1) How much time should the pump run and for how many days? We left it running 24/7 for now but don't know when to have it back to normal
2) After we poured this, what should we expect and what should we do? Should we also add the "fresh and clear oxidizing shock"? or just do the normal service?
3) Should we apply this treatment again? When should we do this? or once is enough? I know you will have lots of comments on this but well, here I am seeking for your help hehehe.....
4) The product says only how to maintain this after "no visible" algae is presents. To apply 6oz. every 5-7 days but it doesn't say what to do after the first application or what to do if after the first one the algae doesn't go away.
Well as always any info. or advise you have will be greatly appreciated.
Let me know if you need any extra info.
Hopefully with this treatment we will be able to control the algae, as i think we will never get rid of it unless the walls material is exchanged by tile or so (currently pebble but not very fine finish, so it has lots of... mmm.. cravings you say? not sure on the word... like little holes where the algae can hide..).
