Aqua Posted February 3, 2006 Report Share Posted February 3, 2006 Hi guys. I've got a brackish tank in my hallway (sitting at about 1.010 I think) and there's all this almost colourless algae growing all over the walls of the tank. How can I combat this, other than never turning the lights on? It's not full salinity, so I'm kinda too scared to chuck a $40 shrimp in there! Any sane suggestions will be gratefully tried out!

JoandWilly Posted February 3, 2006 Report Share Posted February 3, 2006 Hmmm we get algae like that in our freshwater tank to, could have something to do with the water being quite hard with all the minerals in it, cause ours is our malawi tank which is full of coral rock to buffer the water.

Aqua Posted February 3, 2006 Author Report Share Posted February 3, 2006 mine's just standard Auckland tap water (minus chlorine etc of course!)... It looks to me to be too much light, and nothing competing with the algae so it grows unchecked... I'd rather not add chemicals either, if at all possible!

JoandWilly Posted February 3, 2006 Report Share Posted February 3, 2006 yeah ours is normal straight tap water too.... adding the salt puts minerals in the tank that could be contributing the same way the coral rock in our tank contributes.... and our tank gets 4 hours a day with the light on at night and the rest of the time its sitting where it doesnt get direct sunlight.

Aqua Posted February 3, 2006 Author Report Share Posted February 3, 2006 oh true, I'd forgotten about the salts! :lol: Quote Link to comment Share on other sites More sharing options...
