Apparently, nuisance algae can be a problem in a frag tank. My tank is 4' x2' x 8"H, bare-bottom with eggcrate set on 1/2" PVC. Two powerheads create current, plus two returns are connected to a SQUID (alternating flow director). I've heard that eggcrate can leach phosphate which can be a reason for the nuisance hair algae that grows on it.
I am considering a couple of remedies and am wondering if anyone has tried them, or what others think about them:
1) Remove the eggcrate and fill tank with 1-1.5" of coarse sand (like crushed coral) (so powerheads don't disturb sand.) Then, frag plugs can be stuck in sand. One concern is that frags on discs, (or plugs), might sink in sand. So, another thought:
2) Leave eggcrate in place and just fill with coarse sand to level about 1/4" above eggcrate (so eggcrate will be buried and not exposed to light). This way plugs can still be stuck into the eggcrate through the sand.
What do you think of these ideas? Has anyone tried them?
Thanks!
