Re: [APD] cloudy water problem -- or - that funky white water needs more funk

New tank, new setup, new filter?

What's probably going on is something very common. After a
new tank is set up, with new everything, it cycles through
the production of diff chemicals. As it does, it cycles
through the proliferation of diff bacteria. The cloudiness
is actually a bacteria bloom, so you're right that it's not
algae.  It will go away on it's own if you take normal care
of the tank -- althought it could take several weeks :-( . 
If you kill off this bacteria, it will grow right back
because the food source is there for it. What you're
probably missing now, and why the cloudiness will
eventually go away on its own, are the bacteria that thrive
on the nitrogen products but don't abound inthe column but
on the surfaces of objects -- aka, biofilm. These bacteria
take a month or three to proliferate in a brand new
aquarium with brand ew everything. Until they develop,
other bacteria will prosper, including the stuff making
your water cloudy.

Meanwhile you can put a UV on the tank, but that's very
expensive for jsut a few weeks' need. But UV does a great
job of killing unicellar stuff in the water. And it kills
the stuff off about as fast or faster than it can grow.

Is this cloudiness avoidable inthe first place? Absolutely!
Instead of starting with brand new everything, put in some
mulm (detritus -- the stuff that collects in the filter
floss) from an established tank -- it's yeeeuck to you and
me but nutrition to plants and bacteria (takes all kinds). 
Or even take a portion of the filter media (dirty floss,
lava rocks, whatever) from an established tank's dirty
filter and put that in the filter on your new tank. That's
a good healthy dose of "good guy" bacteria and some
nutrition to help them propogate. Basically you want to
culture a good strong colony of the "good guys" bacteria
right from the start.

Another important step is to *plant the heck out of the
tank from day one* and include some fast growers. I like to
throw in some water sprite to float on the water surface 
because it's great at sucking up those nutrients and it's
easy to remove when it's not needed anymore. Plants grab
the nitrogen products as well or better than the bacteria. 

The white bacterial bloom is generally not harmful to your
fish -- just not very attractive. I haven't found the
"store bought" bacterial cultures to be much use -- pretty
much dead and useless by the time someone buys them. An
exception is the Marineland stuff if it's been kept
refrigerated and expiration dates have been observed to
maintain freshness. But you don't need to buy the stuff if
you have an established tank or know someone with one. 

Hope that helps,
Scott H.

Tired of filling that aquarium all the way to the top? Ready to try something a little different? Think less water, more options. Think paludarium.

Aquarium Design Group's Mike Senske raised paludariums to a whole other level. SEE Senske paludariums at
