Definitely worth the extra dollar.thanksss would that be ADA? but they are $$ x10
From: http://www.adgshop.com/Aqua_Soil_s/21.htmSo does aqua soil lower the PH AND Hardness? or just the PH?
Im curious myself ...
http://www.adgshop.com/Aqua_Soil_s/21.htmHere they sell for $42.99 (9L) is that too much or average??
i have 4" in the back of my 10g tanks. check out my journal in my sig, it doesn't look bad at all IMHOIt depends on the size of the tank. 4" of substrate in a 10 gallon would be absurd.
In my Mini-L I have 1.5" in the front and about 2.5" in the back.
