I'd try ADA AquaSoil Amazonia.chiahead said:I am thinking about re doing my entire substrate as I am sick of the Onyx sand and eco complete leaking kh/gh into the water column. In all of your opinion what is the dream or fantasy substrate where money is not a concern.
That's not true. People who used AquaSoil reported that their pHs' fell to 4.5, but this also depends on their original tap water's pH/kH. Chia, AquaSoil simply replaces the Mg and Ca in the water, which leads to lower the pH/gH.turtlehead said:most substrates buffer so it allows the plants to have easier acess to the nutrients and its beneficial. and it wont buffer that much so it doesnt really matter.
Eco-Complete and PowerSand are two different things in my mind. I would compare Eco-Complete with AquaSoil instead.IUnknown said:How about using eco complete over the power sand. Get the benefits of the ADA substrate line, without the change in KH.
