hello everyone, can someone give me some info on getting rid of unwanted algea? I have 5 tanks and each one has a lot of green algea in them. All of my fish are healthy...I'm just having trouble keeping the sides of the tanks cleaned. Could the problem be that the water ph (?) is off in the tanks?
thanx seahunt

Are your lights on too long each day?
Is your tank near a sunny window?
Have you checked your chemicals?

Is the green algae all over everything else or just the glass?

hi Malawi Mother, the green algea is all over the tanks. I use one of those magnetic cleaning devices on a string to clean the sides of the tanks..but keeping the sand clean is bruttle.I have white sand in the tanks instead of gravel...I turn off the lights to my tanks during the day..and I have only 1 tank that's near a window..I haven't checked the chemical levels in the tanks..will do it today.. I'll let you know what the levels are asap...thanks SeaHunt

Green algae to me signifies that the tank is very healthy as far as plants can grow in it. The algae is putting off a ton of oxygen no doubt and your fish are probably thriving very nicely. They also eat the algae which is a bonus, helps keep malawi bloat from occuring.

I personally wouldn't mind the algae growing in my tank on the rocks and stuff, I could see the problem on the glass and the sand however.

I usually get asked how to get rid of brown algae which is usually do to nitrates being high but rarely do I get asked how to get rid of green algae. The only thing you can really do for green algae is to change your lighting to a lesser sun value, clean all the algae you can can and keep up on it as much as possible.

There is one major thing you can do to get rid of the algae and wouldn't normally recommend this but because it is become such an issue in your tank, you can do a total clean out. It would require recycling your tank all over again. You would have to bleach all your rock, glass, fake plants etc etc.

There is always the chemicals to get rid of algae which I don't recommend at all but when weighing it against a total clean out, not sure what I would do.

I would love to have algae in the tank but like you, would hate for it to become a problem with the white sand. I have been trying for green algae for sometime now and just can't seem to get it. What kind of lights do you have in your tanks?

What ever you decide to do about your alge, let me know first so we can work through it together without hurting the fish.

I have a 10g tank for my small fry, a 20g tank for my juveniles,a 10g for my female cichlids that are holding, a 29g and a 125g for my adult African Cichlids. All my fish are healthy. It's just the green algae on the white sand that drives me nuts...

I've got to wait til this friday before I take on this project of getting rid of some algae..due to that I'm currently attending the C.O. (corrections)academy here in Pensacola. Friday is my next day off..I'm starting a new career at the age of 50 lol.

I'll get back w/you on what I decide before I start..thanks for the feed back..Hope you have a good week.. SeaHunt
