If ever I find myself being too lazy to rinse sand before filling a tank, I do one of two things:
1. Dump it in, hope it's not cloudy(this never happens), and then fill the filters with cotton balls to remove particulates faster. This does a great job.
2. If it's a plastic bag that the sand came in, I just sink the bag to the bottom of the tank, then I put a 3-4 inch slice in the bag with a razor blade to allow the bag to fill up with water. After all that has settled out(maybe 10 minutes or so), I cut the bag from top to bottom and along the top and bottom seams so its basically just a pile of sand sitting on a plastic sheet. Then, slide the plastic out from underneath the pile and spread the sand very gently. The water is never crystal clear after this, but it is never more than a little bit cloudy, depending on what kind of sand you used. If you have sand that came in a paper bag, this method doesn't exactly work very well, but you could probably transfer the sand to a plastic bag
Now, as far as pool filter sand goes; keep up on your water changes, because those types of sands tend to leach silicates into the water which are great algae food. Not saying you made a mistake by putting that in there, but there's higher potential for an algae bloom than if you used regular aquarium sand. That stuff never works for me as I have very hard tap water so blooms happen easily to begin with, but I have a friend who's never had a problem with it.
Question: What kind of apistos are they?? I love those little guys.
When I said threadfin rainbows before, I believe what i meant to say was featherfin.
Congrats on the new tank, and good luck!!
