Encouraging pineapple sponge
 

I use to have a butt load of pineapple sponges in my tank but it looks like something ate them or they died.

Anyone know what I can do to start growing them?

I could even set up a separate tank

I know in my tank they grow we're there is little light. I also use tap water in that tank.

Yeah mine were in low light too. But now nowhere. I've never used tap water

I think they grow well when they have nutrients. If they decline, your water must be in better shape.
If there aren't any left, I guess you will have to import one from a friend, to see if it multiplys. Are there any in the sump?

Got a sump? They grow in my overflow and sump...don't see them in the tank.

Yeah I've got a sump with a bunch of rock. But no sponges on the underside of any of the rocks

zeovit sponge power additive

+1, this stuff works wonders for sponge growth. Although risky adding multiple sources of healthy liverock and have many shaded areas also causes the stuff to explode.

Mine grow in my sump and my old remora c hob I have modded for sponges in my sump. Modded by mistake lol. But it works great.

Modded how? I think I might set up a dark 10 gallon just to grow these

+1, Zeovite sponge power. I have tons of non-photosynthetic sponges in my tank and I feed sponge power each day two drops per day in my 75 gallons along with amino acid.

Thanks guys. And this powder can be used stand alone?

It's not a powder it's a liquid in a little bottle. It's pretty expensive but since you only use 1 drop per 25 gallons it last for a very long time, even in large tank.

cool, thanks for the info.

im probably just gonna set up a 10-20 gallon tank specifically for growing sponges..... then feeding them manually to my moorish idol

Do a little googling on cryptic refugiums, lots of good info out there!

thanks. ill do that
