I need some advice. I have a 90 gallon reef tank that has been set up for almost 2 years and run perfectly until recently. I have not changed anything other than adding coral and we had a lighting change to the new T5s about 3 months ago.
The hair algae has grown crazy. I cannot get rid of it. I have tested my levels, my nitrates are at zero, phosphates were borderline but not high. I have done water changes, added turbo snails, pulled the algae with my fingers, added a phospate pad, cleaned the skimmer. I cannot think of anything else to do.
The sump is a homemade 20 gal
long sump with a protien skimmer at one end. We have one double and one single wavemakers at opposite ends and live rock filtration in the sump and tank.
I am starting to think that my sump is not right. The set up maybe? The skimmer does not seem to be skimming anything. It is the bubble version and the bubbles never make it to the top. We purchased a larger skimmer with the intention on using it on a bigger tank, so I dont think size is the problem.
I am looking for any advise, I will try anything knew. I have asked my LFS
and looked on line with no luck. The LFS
just told me to add microbacteria and the problem would go away. Three weeks later - it looks worse not better.
Please feel free to give me any advise, If my setup is wrong, I want to change it. See pictures below.
We removed by hand a lot of algae last night, but you can see there is still a lot.
