I’ve used Phos-Zorb in my 30-gallon saltwater tank for three months. Algae growth has dropped significantly. The media is easy to install and doesn’t clog the filter. Works well with my existing setup.
Carl Mitchell –
Good product for reducing phosphate. I noticed less green algae after using it for two months. It’s a bit pricey, but the results are noticeable and worth it for a stable tank.
