I added this stuff to one of my tanks yesterday, have read a few good reviews and the black/white sand combo sold me. However, this mix creates a high PH 8.2 + environment more suitable to african cichlids, and as of right now the only thing I was planning to put in the tank was livebearers. Does anyone have experience with this stuff? Will the livebearers be okay? these 2 paragraphs i found interesting, just wondeirng if it was sales pitch or tried and true. In addition to maintaing the pH of your African cichlid aquarium, Eco-Complete™ for African Cichlids is also high capacity bio-filter. Aragonite is extremely porous, about 20,000 square inches of surface area per cubic inch! Imagine the beneficial bacteria population you can maintain with it. This is why Aragonite is unsurpassed in reducing nitrates, nitrites, and ammonia, allowing a bio-load many times greater than other substrates. You would have to buy 4 bags of ordinary gravel to equal the surface area available for water purifying bacteria in this one bag of Eco-Complete™ African Cichlid Substrate! Further differentiating Eco-Complete™ for African Cichlids from other substrates, it's biologically complete. Foremost, each bag of Eco-Complete™ contains live water-purifying bacteria. This makes for cycling a new aquarium faster and safer! This substrate also creates a natural biological balance to discourage nuisance algae in the aquarium. Most substrates require a tedious rinsing ritual whereas Eco-Complete™ African Cichlid Substrate! needs no rinsing at all. It's packed in a water conditioning solution for immediate results. all input is welcome, thanks!
