ideally i want as little substrate visible at the bottom of the front glass on my tank as possible . there is a black band around the bottom , which i have just measured , and it is 20mm . whilst i dont expect that to be deep enough , i dont want to go any deeper than absolutely needed at the front for the HC. what is the minimum i could get away with ?
