Its an ok substrate, but for the price go get a bag of dirt and pool filter sand and you will have even more growth from you plants than with eco incomplete. After about 2 months all the nutrients are all used up so save the money and get something better

Avoid! Raises pH. Kills Fish

I have been having problems with maintaining a stable pH of my water so I removed everything except the eco-complete, live plants, 4 otos, 4 wag-tails, 2 bamboo shrimp, and about 8 assassin snails, yet the pH keeps going up to 8.2.

Great Substrate for Plants

Right after I changed over to Eco Complete my Rosette Swords and my Red Melon Swords just took off growing. Also, I received many complements on the look of my tank with Eco Complete Black Substrate, and how it made my fish and plants stand out. I recently upgraded from a 29g to a 75g and order a few more bags of Eco Complete so I would have enough for the 75g tank.

Fish tank extras

Works good so far, it did give way to my pumps so I had to move them up higher. Plants look good, I haven't seen any chage one way or the other. No clouding what so ever. It gets a natural conture with the current, I like it.
