Just to keep it fair and balanced
, I pulled my Prizm out of the garage last month and put it back on my 30g. After days of tweaking and pulling both a wet and dry foam....I was unable to get anything but a watery, very weak cup of tea by the end of each week. I just don't find this to make any difference in the tank, especially not for the $100 price tag back when I bought it. Is anyone pulling out anything thicker and darker, I would like some other opinions....photos would be even better. It's tough to quantify sometimes what is a light/medium/heavy bioload so I wouldn't mind comparing.
