will sand ruin my filter ? | Freshwater Substrates
Nov 10, 2012· I use pool filter sand that I picked up at Home Depot for 5 bucks and change for a 50lb bag.I ran 2 Fluval 305s and a Fluval FX5 with the intakes about 4" up from the bottom and never had a problem with sand getting into the filter.I sold the 2 305s and I am installing another FX5 tomorrow on my tank.The sand looks better IMO then gravel so if you want it go for it.

What Is the Fineness Modulus of Fine Aggregate
Natural sand or crushed stone is used to achieve a fine rating, with most particles passing through a 3/8-inch sieve. The sand and stone comes from a pit, river, lake or seabed. Aggregate is described as coarse when the number is higher than 3.1. Coarse aggregate comes from quarry rock, boulders, cobbles, large gravel or crushed concrete.
Soil Unit Weight on the Geotechnical Information Website
Unit weight of a soil mass is the ratio of the total weight of soil to the total volume of soil. Unit Weight, g, is usually determined in the laboratory by measuring the weight and volume of a relatively undisturbed soil sample obtained from a brass ring. Measuring unit weight of soil in the field may consist of a sand cone test, rubber balloon or nuclear densiometer.
