My largest Oscar tank (a 120) has pH 7, GH 5, KH 4, KNO3 13 and P 5
(I can not measure over 5ppm with my Hach low range kit.

I am thinking of moving 5 gallons to the 55 once a week to supplement
P and KNO3. That would be cheap....free.

Any reason this would not be plausible?

because my tap water has tons of phosphate in it. (Some hobbyists would
consider that a nightmare, but I consider myself lucky.)


Take the stick in the eye out to reply.
