I have developed green algae in my tank. I just had the water tested and all levels were good. I can clean the glass and in two days, there are signs of green again, and is also coating my live rock. The snails cannot keep up....I think they are too full !! How can I fix this? I also have some bright green and deep red spots growing in my tank. Is this Corrilline Algae?

What are your water parameters?

[mkossa]

Can you be more specific. I am a newbie and have been relying on the local dealer to test my water. The tank is 4 weeks old, 14 gal. Bio cube, 15 lbs. of liverock, two soft corals, two clowns, live sand as a base, water temp 80 deg. I am only running the powerhead that came with the unit, but was told to add another. I have done 1 25% water change, which seemed to accelerate the algae growth.

What kind of water are you using - tap water or RO? Tap water contains all sorts of nutrients that will cause algae to grow.

I've been having some similar algae problems. I think its because I use tap water. not RO. Although I live in an area with some of the best ground water in the country, there is always stuff in any unfilter or RO water.

Good luck with that, i let ya know what werks fo me!

i dont mean to sound like a jerk but did i read ur tank is 4 weeks old and 14 gals
if so who would let you stock your tank with corals i think i would look for a new store that gives better advice
like i said i not trying to coe off rude but a 14 gal tank 4 weeks into a cycle isnt stable enough for corals imho
i think your alge blooms are part of a second cycle most tanks get
anyhow good luck

Okay, so I have a tank that wasn't set up correctly as I have corals in it too early......what do I do? I do use RO water for my water changes. I guess I am looking for that better advice. Do I pull the corals?

I had to cut back on my light time. I want to see the tank til 9pm, so now it doesn't turn on til Noon. That made a big difference for me. Also I added later on, an ionizer called Aqualizer. That made my water seem to stay much cleaner and reduce the green algae.
