Well I just got done moving my 29g apisto display tank and took the opportunity to switch over to sand (been wanting to do this for awhile). Although I've used pool filter sand in tanks before, I was told by lfs guru (This guy know more about fish than Jesus) that silica based sand can cause damage to fishes gills when sifted. So I went with the Estes Marine sand which is not silica based, but still inert. I mixed one bag of black with two bags of white and came up with a color that accented my slate caves and HUGE piece of drifwood nicely. The 15lb gave me just the right amount of coverage for the 30x12 footprint.
I put the sand in straight from the bag (no rinsing) and filled tank by pouring water over the driftwood. Some of the sand floated but with a little aggitation it dropped like...well like a little stone. Long story short, There was next to no cloudiness at all, and it looks great. I was very impressed. The higher price (1.00/lb) was totally outweighed by the ability to skip the hours worth of rinsing and two days of cloudy water. The mix of black and white shows of the cichlids better also (They tend to look washed out on white sand).
I would recomend this product to any and all cichlid owners.
