algea issue

[abraham]

Hey folks,
I've had my current tank up and running now for about 13 months. It's doing great. the water parameters, etc. are good. I have (in the last three weeks ar so)had a very irritating algae "bloom" happen in my tank and refugium. The stuff is a brownish color and is like a stringy slime. Anyone had any experience with this or am i the only lucky one. It's not over whelming the tank or anything like that, it's just here and there and looks ugly. Nothing eats it either. Any thoughts?

probably cyano....

Few things to help:

1) Use RO water and reduce feedings to cut out excess nutrients
2) Increase circulation via extra powerheads, etc.
3) Suck it out via siphone tube when doing water changes.

I used chemi-clean and it worked really well. Have you done any lighting changes recently?

it really doesn't look like any cyno that i've had in the past. this is brown with a greenish tint

Sounds like the same stuff I battled for several months last year. The cause of mine was the RO/DI water I was buying from a less than desireable LFS. Their water tested to 35 TDS. I stoped buying water from them an my alge problem is gone. Check your source water, and not just for nitrates or phoshates. My phosphates and nitrates were zero the whole time I had this problem .

if it's a brownish slimy/stringy algae I also battled something that sounds similar. Mine was also due to an RO/Di problem (membrane too old). I replaced the membrane and DI cartridge and the algae disappeared in a month or two.
