Have a 50 gal with a few goldfish - previously had an ?ich outbreak or
something and used quick cure for 5 days- fed antibiotic food - and used
spectrogram antibiiotic in the water - but only 1 or 2 doses
Anyway - the previous fish died and now have new fish.
Tank is cycled as indicated by outbreak of brown algae ( also added biospira)
Problem is persistent white cloudyness with outbreak of brown algae on floor
(barebottom)and on glass sides. Daily water changes( 30 -40 %) help only a
little
Have 3 filters running - so excellent filtration. Have cleaned sponges.
Questions: - is this due to the prior chemicals?
Is the aeration ( bubblewand and small powerhead) affected and contaminating
the water?
Do I need to run a diatom filter?
Do I need to take fish out and drain clean and fill the entire tank?
many thanks
Ira
