Is this bad for my fish?
Ok, I have a 29 gallon marine tank. This is my first, so it's trial and error. I have a clownfish and a royal dottyback. There are two good sized chunks of live-rock in there. Crushed coral for substrate. Using a Cascade filter meant for 100 gallon tank. Fish appear to be very healthy. Haven't seen a change in behavior.
I have a reddish algaeish thing growing on the substrate. Very little grows on the glass. When the tank was new (about three months ago), got lots of algae on the glass. I mean loads. Lights are on from 7am-11pm, which I'm sure is a bit more than needed. Do the same thing in my planted freshwater, but the pleco takes care of any algae. I don't have any algae eaters in the salty.
Anyways, I'm assuming chemical levels are getting higher (haven't checked in several weeks. Been very busy with work). The algae bloom on the glass completely died out. Now though, there's a reddish growth on the substrate. It's actually growing to the point that it's a bit stringy and waves in the current from the over-powered filter. It started as a little bit of reddish algae on a piece of live rock, but now it's coating nearly the entire bottom.
Again, the fish appear to not be having any negative effects from this. Is this algae-like substance dangerous, or is it merely unsightly. I'm sure the tank needs a water change to get the chemical levels back down a bit. Hasn't been changed in a while because I'm still a rookie when it comes to mixing salt properly. I lost two anemones due to water parameters being unstable. I'm told inverts are more sensitive, and I'm sure their deaths added to the chemical levels.
Is it just all the light creating this algae. Did the likely chemical spike after the anemones died kill the brown bacteria on the glass and allow the red stuff on the bottom to take over?
Do I need to be worried about this growth, or is it merely an eyesore?
In either case, what could be added to the tank to combat this. Would a starfish eat this stuff? Is there some kind of marine algae eater I could add to the tank? Even if it's not dangerous for the fish, I'd like to tank to look a little bit better.
Any help would be totally appreciated. Thanks.
