cloudy darkish water

MPS is acidic so if the green, or at least some of it, is from metals then the green may have gone away when the pH dropped and then come back when the pH rose again.

Ahh! I forgot that it was so acidic. It's been a LONG time since I messed with MPS.

Thanks, Chem_Geek.

The equivalent amount of oxidizing power as 1 ppm FC when added as MPS (6.7 ounces weight per 10,000 gallons) has the same acid effect (after usage/consumption) as 2.5 ounces of full-strength Muriatic Acid (31.45% Hydrochloric Acid) per 10,000 gallons. It's actually somewhat more acidic for equivalent FC than Trichlor.

Ok. FC is 7. CC is 0. TA IS 80, CH is 350. CYA is 55. Ph is between 7.6 and 7.8

I did throw in some algaecide last night and now water is milky white and can see the bottom of deep side, thiugh not clearly. The stuff is called skill-it from biodex. Before I threw the algaecide s the water was still green despite running filter 24/7. I never tried the cellulose fiber and will be returning it.

Been running filter and threw in some DE to where pump psi went from 7.5 at clean back wash to now 8.5 psi. I'm going to the store right now to get the stuff to do the metal test.

Chemgeek, I will follow your instructions once I see what's going to be the conclusion with this algacide. I threw in the algacide last night and read your post this morning. Oh, the water color now is like a pale white blue.
