fiberglass screen vs fabric type barrier

Lynn, i just saw this. i think the hydroton would actually be more beneficial to the biological filter. they may be smooth and round, but i think it's what we can't see that makes the difference. i would venture a guess to say that it really isn't as smooth as we think. i believe they are covered with microscopic holes from air pockets in the clay as it was being dried. leaving a really nice amount of surface area for bacteria to grow on. not as smooth as the rock would be. i know microscopically, the rock would be textured as well, i just think the clay would beat it out.

Yes, I'm sure your right! Like our aquariums , it's what ends up in there that matters.
I have not replaced a sponge filter in my 2 fluval 405 in 5 years. I just rinse ! Think of all those $10 dollar bills I saved !
I have a 9 year old Discus spawning ( right now ) once every 2 weeks .

The male I have is too young. I lost her mate after the hurricane The girls try ?.................. It's hormonal mayhem !!!!!

I'm wondering if I should put hydroton under my false bottom for bacteria reasons. hmm

it's not necessary with a false bottom Dee. Lynn is running a hydroton base. no false bottom.

i'm going on 4 years on my 405 sponges. 2 years on my fx5. they are the only filters i run with sponges. everything else is straight lava rock for bio only. i have a buddy who breeds discus. you must have the patience of a saint for that....LOL
