If im wanting to do carpeting plants, what's the downside to doing a finer substrate?Hello; I have found a thicker/deeper substrate to favor plants. Four or even more inches deep layer. Also not too fine of a substrate. BB sized as a sort of minimum to small pea sized.
Hello; From personal experience I have tried construction sand simply because i had a pile around. The plants did not do well. I think it was too fine grained and may have compacted too much for the rooted plants. It was however fine for my pair of Kirbensus cichlids. They found it good to dig into.If im wanting to do carpeting plants, what's the downside to doing a finer substrate?
We deal with this in the saltwater side as well, you need to be careful about stirring up the sand. The method i was wanting to use was a layer of gravel to build up the topography I wanted, a layer of pond soil and then a thinner layer of sand to really just keep the soil down.Hello; From personal experience I have tried construction sand simply because i had a pile around.

The other issue with fine grained substrate is the problem with toxins which can accumulate. Seems the sand can form anerobic pockets in which bacteria can thrive and produce toxic byproducts. Reports on this in this forum.
A way around this if you wish to use sand is to DRY SIFT it with a screen. I made such a screen with 2x4's and screen wire. Got rid of the dust and finer sand particles. I could come up with various grain sizes.
