i just started using sand. planting is a breeze, but after pruning stem plants, the rootless tops can float easily until they root again. fine sand can compact and, supposedly, make it hard for roots to develope, pool filter sand is a heavier grain that will help with this problem. it still looks great and is less cloudy. sand doesn't have any nutrient value, so layering it over something like ADA aquasoil or laterite will do wonders for rooted plants, but they will eventually mix after a lot of rearrangement. anarobic pockets can build up over time, so sand needs to be stirred about once every month or two, malaysian trumpet snails help this process a lot.

Once I started using pool filter sand, I switched all my tanks over to it. I've never had a problem with it compacting. To me it is easier to plant in and holds the plants down better than gravel. The most common color is tan, but it can be found in white also.

How deep should the sand be when using pool filter sand. Thinking of using it when setting up my new fish room. A friend just donated 4 tanks to the project. Three are old commercial tanks, 3' long 75's with 1/2" thick glass. How much sand do you think it'll take to fill one of those?

I usually keep my substrate dept around 3" or a little deeper for slopes, I try not to go over 4" deep. I would think for a 75G tank that 2-3 bags should do it.
