hey you might wanna try t-grade color quartz, it is better then sand , it fine like sand but heavier. it will not get in the filter. as far as prewash i would wash it but you do not need to wash it. i rinsed it and it was clear when i did it it comes in 51 lb bag and one bag fills a 55 gal tank, it comes in various colors snf my cichlids love it
Howell (Livingston county) and home depot. Next time I'll spend the extra $ and get pool filter sand. I just didn't feel like going in the pool store while I was already at home depot.
I also wanted to get a pool filter sand the white one but when I went to a pool supply store the only color they got is the beige one I wonder what you call the white one and it's kinda hard to look for it.
