Well Apollo how is the system doing this week. Did the eggshells work to slow the dropping ph? Colors come back in the fish yet? Don't leave us all hanging here.
Sorry, been busy chasing the dollar and working on my Vertigrow System.
I put about 2 dozen boiled quail egg shells in a mesh bag and place it into my FT. It slowly brought the PH up to 6.8 - 7.2 depending on which tester I use.
All the fish seems fine except for the largest one, his gills look gray instead of pink. But then again he's one of the Pink Tilapias that slowly started turning light to med gray. This color change started weeks before the water shortage, not sure if this is something to worry about.
