It is a post ike development. I tend to agree a sea hare doesn't address why the algae is there in the first place. Part of it is new tank settling. This tank has been up for 4 months or so. The ike shock didn't help. Lots of waste built up. And it just kind of took off, really fast. I've done the lights thing (It helps) was to the point that I wasn't feeding my tank much at all. I'd used chemical means to reduce po4 and no3. Wasn't seeing any reduction in the algae.
So it was an excuse to try and set this up. I'm actually quite pleased with the results so far. I'm seeing a significant reduction of HA.
But I do tend to not add anything that feeds on something in the tank. Because with my size of tank it really isn't sustainable.
I do understand the other means of removing algae, and have done so in the past with different tanks. Just this bloom provided me a "if it can do this than it can do anything" situation to test out this idea, i've seen promoted on other forums.
If the goal was no algae tonight, I could do that. But the goal was well lets see what this will really do...
