what to do about algae control?
all alge eaters have been eating?

thanks jason:confused:

Reduce your light to no more than 8 hours total. Most people keep their light on for too long. Try brittle stars and turbo snails.8-)

Turbos could possibly be eaten by the octopus. The best clean up that the octopus shouldn't bother is Serpent Stars. I think brittle stars would probably be a bad idea too because they are pokey.

A saltwater aquarium is a complex chemical system and its pretty much impossible to solve a question like this without more details about the system in question. Really, any attribute is an important part of the analysis--right down to equipment brands and techniques. Right now we don't even know how big the aquarium is or how its filtered.

Or how old it is. The longer I am in this the more I realize that algae issues happen to newer tanks. So, besides the stuff Dan wants to know, I think we also need to know what the algae looks like.

Hi Ihave a 55gal Marinland filter its been set up 4 months red and brown algae. With small octopus not sure what type yet. Got it about a month ago,grayish with bumps on head. It eats beach crabs and sand fleas hermit crabs but not small shrimp whats up with that? It used my snail to prop up a rock now the snail is stuck and pushes the brittle star fish around I know I run lights too long. Try to cut back. What do you think about blue leds would still grow algae?

thanks jason

Sound like cyano and maybe diatoms. They often show up around 4-6 months. :grin: However, they may be due to a nutrient problem. I would test your water parameters and manually remove the cyano and algae/diatoms manually with a fine brine shrimp net or via siphon.

Which Marineland filter? Canister or hang on back? Either way, do you change the filter media regularly (and if so how often)?

LED's should result in less nuisance growth, however, if your nutrients are high and are causing the growth, you still have a problem you should address.

Marineland 350

How often do you clean it? If you don't clean it regularly, you get nutrient build up and poor water quality. The mechanical filter doesn't remove goo, it just collects it, so you have to clean the mechanical filter and filter medium or the goo rots.
