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 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
