Re: Going filter less

>>There is very little circulation in the tank now
compared to the two bio-wheel filters that were hooked

Dave, I think we need to know the specs on your tank
first.  Size of tank, fish load, lights, etc.

I would think that you would need circulation to help
distribute co2.  Try measuring co2 levels close to
your reactor, and then far.  See if there is a

A filter in an established tank does primarily two
things IMO:

1.  provides circulation
2.  mechanical filtration

You might have decreased water clarity during the
times that stuff gets kicked up from the substrate.

circulation will this also
help cut down on the amount of algae?<<

I have heard people say that stagnant water is good
breeding grounds for BGA.  Have I had BGA in stagnant
areas?  Yes.  But whether the connection is very
