I would say most of us have had to, or are currently battling some pest or nuisance algae. So lets hear about it and what remedies helped you.
As for myself i've battled aptasia, aesterina's, and bubble algae. The aesterina's being my least concern as for now because I haven't seen them eating my zoa's. That being said I picked up a harlequin shrimp to clear them out, and in the future i'll just feed him chocolate chip stars. As for aptasia, if its a small rock I can pull out then I turn up the heat and burn them off, otherwise peppermint shrimp have done well for me. Lastly and the thing I hated the worst, bubble algae! What a nightmare that stuff is. When I first started getting them I didn't know not to pop them, big mistake. I had to remove rock and scrub them off then rinse the rock. Also, I use chemipure elite and a phosphate pad to reduce nutrients to starve them. I'm happy to say I haven't seen any bubble algae in months.
