> 3 dayThe amount of media you get for the price is just ridiculous. Seachem seems to be getting greedier every year.

> 3 dayThe beneficial bacteria colonized this media in no time. I replaced my old biomedia with this when I moved my tank and have had no ammonia, nitrate or nitrite detections since. My plants help out as well but I would definitely buy this again as long as the price is right.

> 3 dayIt may not be the most surface area per cubic inch. Compared to newer products on the market. But its been time-tested. Its cheaper and easy to use ... No worries about leaching aluminum or other metals.
