persistent white cloudyness in a cycled tank

[MartinOsirus]

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

What color is the water? Is is a white cloudyness or greenish? If greenish
it may be another algae problem!

See this site as it has information on all common types of algae.

Its whitish cloudy - I don't think its bacterial bloom - cause tank has cycled
-there is the brown algae. Ammonia and nitrites 0. Haven't tested for nitrates.

My Goldie tank is overfiltered and gets cloudy very often as
well.
I couldn't figure it out until I ran a diatom filter on it for a
few hours- the "muck" was bright green when I cleaned the
filter! All I have is a bloom of algae in my water column-
unattractive but not a problem. It appeared white visually while
in suspension but was most definitely green- smelled just like
wheatgrass juice!
I've cut back a tad on feeding to eliminate excess nutrients,
and cut back on lighting a bit also.
The problem (in my case anyway) is a barebottom tank that I keep
way too spotless- I believe that if I could tolerate leaving one
pane of glass algae covered it would help tremendously. I do
have a few plants in there but all are very slow growing and so
do not help much with the algae.

Just my experience...
