Thanks for the info. Do you know anything about Schultz aqua soil or what ever that brand name is?
I have Schultz Aquatic Soil mixed with gravel in a 10 gallon and in a 40 gallon as per my signature. On the positive side, it grows plants almost as well as Seachem Fluorite at a fraction of the cost. I say this because I have grown plants in both. On the negative side, plants seem to uproot once they grow deep roots and do not stay anchored. That is why I would not use Schultz Aquatic soil again. The plants need to stay rooted and anchored to be firmly established and to avoid any problems. A possible way around this if you want to still use Schultz Aquatic Soil is to lay down a 1" layer of pool filter sand, plant your deep rooting plants firmly, then cap with Schultz Aquatic Soil. The sand will keep the plant roots anchored and you will still benefit from the high CEC of Schultz Aquatic Soil as a cap.
