After using Penn-Plax Pro-Carb activated carbon, I believe it is the best carbon I have used to this point. The Pro-Carb comes in pellets that do not break up and get into your system water. Also, when I wash it out prior to use, no black water leaches from it after a few rinses and the "crackling" sound is much louder and active than other brands....I assume this means it works better?
This stuff is hard to find though. I regularly buy it at PJs, but last night there was none left so I ordered some online.....much cheaper even with the shipping charge it is around 50% of the price. PJ's sometimes has it but not always and most of the time it is the small 28 oz bottles instead of the 57 oz bottles.
Anyway, I had been using it on my QT for a while and had absolutely clear water with no algae. After 3 days of using another product, the water is noticeably less clear and algae is beginning to grow. Even after washing it over and over, I could not get the water to run clear from it. Also, little bits of carbon were released into the water....no big deal but unsightly. I guess the old adages are true: "Stick with what works" and "If it ain't broke...don't fix it".
