Just bought (2) big bags of ecoscraps organic gardening soil for my 65 gallon planted tank as i didnt want to buy any other soil that had bark in it as most do. I was wondering if anyone has ever used this stuff before? And would it be a good idea to add burpees garden coir in there? The garden coir has the appropriate ph and everything that most aquariums require, i just don't see that my bags of soil contain any of thay or is it not necessary? I would appreciate some advice .Thank you.
