Re: [Killietalk] sponges

Tim, I had a very similar situation just a few weeks ago. I set 3 55's up in
direct sunlight. Two, one fresh and one marine, grow  little to no algae.
What does grow is a very healthy hair algae which I am finding is a VERY
attractive killie spawning medium.

The third was such thick green water you couldn't see a fish 1 inch behind
the glass.

Dr Goldstein suggested the solution to that problem for me. Put a few
hundred Daphnia (Moina) into the tank (of course take any fish out first).
They'll clear the tank in about 3 days and you'll have lots of killie food
to spare.

Got to admit I use sponge filters in all my tanks. I buy loads at good 
prices & sell hundreds out across the world. I have noticed that in all 
these hundreds of filters the sponge composition is different. Some sponges 
really collect the muck & cleaning results in a real sludge whilst others 
are really clean. These collect little muck. I think it's a fine balance on 
sponge density which works best.
I'm presuming your Hydro sponges are comparible to our Algarde sponges.

A mystery for the grey matter. Two tanks side my side in equal full daylight

with equal fish, plants, snails. One tank remains green & requires 90% water

changes the other remains clear & requires little water changes.
It's a little experiment I'm doing. The only difference is one tank holds 
lyretail guppies - the other holds wild Poecilia caucana.
Which tank is causing the green water problem?
Do different sp. produce more waste products as food for algaes?
