Brown algae?

After finally getting of my problematic green murky water situation and now
enjoying a clear tank, I notice that the walls of the tank are getting a
brown film. I used an algae "scrubber" to clean down the sides, but the
brown returned quickly. Since switching to an Aqua Clear three way filter
and only putting a capful of "Cycle" in the water, I don't want to start
throwing all kinds of products in the water unless I have to.

Any input greatly appreciated.

Sounds like Diatoms. Monitor your nitrate and phosphate levels. Also replace the
light bulb
if its old - my old light caused massive diatom problems and replacing it with a
broad spectrum
fixed the issue.

Thanks, another question......what is a normal range for nitrates and
phosphates?

My light is flourescent.....should I still change it?

Thanks for your input.

For nitrates it's less than 40ppm, preferably less than 20 if possible.
I can't recall from memory what Phosphates were.

OK, just a dumb question, I have tested my water and all the readings are
perfect, except for the nitrate's which are too high, so what do I change,
or add to get them into the normal range? How can all the other numbers be
OK and just this one way off? I have 3 ponds and one 50 gallon house tank,
all treated the same way, and yet only have trouble in one pond. Help me
understand what is going on. I have 2 fantail gold fish in the 50 gal. 7
....4 inch comets in each of the 150 gal. and 7... 8 inch comets in the 300
gal. all 3 have pondmaster pump/filter systems that are 3 times the required
size of the amount of water. If that info helps. KatAZ

You didn't say which pond has the Nitrate problem. But I believe the
recommended gallons per Goldfish for a pond is about 40 (So you seem OK
here). It's higher than the normal 10 for a tank, as you don't normally do
water changes in a pond. Does the problem pond have a proper biofilter? Is
the pond cycled?

The usual prescription to lower nitrates is water changes. You may also try
feeding less, and adding more plants. I rarely feed my pond fish,
unfortunately they have lots of string algae to eat.

I believe between .5 PPM and 1 PPM of Phosphates is recommended. Although
some people say the ratio of Nitrates to Phosphates is also important (about
10 N to 1 P). Since your Nitrates should be below 20, this gives you a P of
2 or less.

Diatoms bloom when silicates are high. Often new tanks that are filled
with tapwater have a diatom bloom. It should go away on its own.
