JFR Posted November 6, 2021 Share Posted November 6, 2021 I'm overhauling an existing 55 gallon tank and planning to start over with different substrate, filter system, etc. for an aesthetic change, as well as to make it more hospitable for plants. I have extremely hard water that is slightly alkaline. I was given 2 8L bags of the Dennerle Scaper's soil which I am aiming to use as a base, with the recognition that it will lower the pH and soften the water. I don't have enough of this soil (and don't particularly want to purchase more), so I'm trying to figure out what to put over it. I don't mind using an inert material on top and supplementing with nutrients. I'm wondering about EcoComplete, but I've read that it might actually RAISE the pH. Can someone tell me what effect that might have on the water and the longevity of the soil if I combine these 2 competing effects? Alternatively, would I be better off with 1) more of the plant friendly substrate, or 2) regular inert gravel or something such as black diamond blasting sand? Thank you in advance! I've learned so much from this forum. Link to comment Share on other sites More sharing options...
