Hi I can see the other post, but could not see the volume calc.
I have a 36 x 22 x 26 tank which I am going to be setting up for CRS shrimp.
Is a 3 ltr bag of substrate enough or should I get a 9 ltr bag. Or better off can someone show me the calc.
Want to have some landscaping but clearly not...
Just curious, as its coming up to 1 year with my first tank.
It has a 1cm layer of Tropica substrate with white/cream colour sand on top. Medium planted.
Does the substrate loose its nutrient qualities? Should I be replacing it ( not that I am in a hurry)?
Thanks in advance.
