Hi sorry for those of you not from hawaii, this question is not meant to be discriminatory. So for my fellow members who are from hawaii I have a question, regarding sand. I wanted to use sand in my lake malawi tank. Now i've checked home depot, city mill, and lowe's, does anyone know where i can get play sand or pool filter sand because i used the coral sand that i saw all three stores selling and it was a bad experience. The particles were so fine that it made the water extremely murky. Now i have used the artificial sand the lfs sell, but as we know it's really expensive, and my tank is 45g. If anyone can help me i would really appreciate it thanks.
