algea bloom!

Hi,

I don't know how to say this, but congratulations...you have created green water. Also known as phytoplankton and this is good food for your corals. People actually pay $40 for a gallon for this stuff [img]smile.gif[/img]

In any case, this is caused by too much nutrients. The simplest way to fix this problem (not that it is a problem) is to buy a micron filter cartridge for magnum 250/350/300 canister/HOT magnium. I used some duct tape and converted my power head such that the intake water passes through the micron filter.

The other way is to a 95% water change and lights out for 2 weeks. And then another 95% water change.

Nutrient export is important in a skimmerless system -- you may want to look at implementing an ATS. This is much more effective than a skimmer.

Hope that helps.
