Hey all, So like many of you I have a refugium in my sump. I'm currently keeping cheato and ulva in there and slowly it is disappearing. It seems like the massive amount of pods that are living in there are eating all of it. When my tank finished its cycle I ordered a mixture of different algeas from indo pac. The pods consumed all four bags of algae within a month. My fuge is 20"long by 8" wide and the entire surface of the water was covered in macro algae to about 6" deep. It was a lot. Since my refugium was almost empty i added another large ball of cheato from my lfs. That was a week ago and its already half way gone. My concern is that this process is actually detrimental. Right now I am having a phosphate issue that is causing another cyano outbreak. I am wondering if this could be happening because the pods are breaking down the macro algae back into the elements that the algae once absorbed. I barely feed my tank and have only coral and inverts. I think part of the problem was insufficient lighting in the refugium since nothing seemed able to grow. So I decided to swap my coral-life macro gro light for a 20" t5 fixture. After doing some reading on freshwater planted tanks I thought it would be good to try using a 670nm bulb with a 460nm bulb. The reading i was doing about planted tanks that those were within the most important ranges for growing algae. I added the fixture today so well see what happens. any thoughts?
