| Re: Purigen
If your Purigen is turning brown after only a couple days that indicates you have quite a bit of organic waste in your tank. Purigen can be used along with carbon as well as a phosphate removing media, and using Purigen with carbon will make it last longer. Purigen is also less aggressive than carbon and I don't think it removes phosphates.
The reason your algae growth has slowed is probably because the Purigen is pulling out organics the algae was feeding on.
Purigen is a great product in my opinion and I've been using it for many years, I usually buy it in the 100 ml. size which already comes in its own little bag. |
