Please Help. I Have New Salt Water Tank That Im Setting Up For Fish Only. Right Now I Have 3 Fish In It And They Look To Be Content. Let Me Back Up It Is A 20 Gal Tank That Has Been Running For Like 3 Weeks And Fish In It For About 5 Days. Ok On With The Story, There Is So Much Brown... Algey I Guess That If I Clean It Maybe 2 Days Later At The Most Its All Back. It Covers Everything And I Mean Everything. What Is This And What Can I Do About It. Please Help It Starts To Make The Living Room Smell Bad. Thanks In Advance
 
I would love to help you, lets start with the type of fish you have in the tank? Also too, do you have a protein skimmer running on this tank? Is this tank located in the vicinity of a window? When you test the water, what are the levels? Because if this tank has been up and running for three weeks, I'm pretty sure that its not fully cycled.
 
I would like to know also I don't have much of it but if it gets all over the tank I do. It is only on the sand and I have cycled the tank and it has been sitting fishlles for abot 1-2 weeks after that up intil now I have been using a 2 bulb incandassent fixture wich is so old the switch doesent work so ihad to unplug/plug in to turn on/off . My fish book says that it happpens when you don't have enough light wich i didn't. I upgraded to a 36 watt double tube t-5 coralife aqualight today, I think I solved the problem but my fishbook is the innes 19th edition revised so it's like40-50 years old and is mostly freshwater I could be wrong. The tank has 1 occeleris clown.

lets see if i can help

well do you have any algae eating animals in the tank? if not try some turbo snails and hermits. also a protein skimmer would help a lot. another thing to take into consideration is that your tank is going under the normal conditioning where there is a spike in algae growth before it calms down and equals out. also because u have 3 fish as your first in a small tank the phosphates and nitretes are probally high causing algae growth.a 20 gallon marine tank has about a compasity of maybe 4 or 5 3 in fish with a good fiter on it so u basically added more than half the capacity of the tank so the algae is normal. To sum it up get a cleaning crew of crabs and snails in there and wait it out. the conditioning period 4 a tank is usually 5-6 months where in the 5th and 6th month most pest algea dies off and is replaced with desirable algae. good luck!
