Powerhead placement / aim
So I've been trying to figure out how to place and aim my powerheads for the best flow without blowing sand all over the place. My current setup in my approx 30" x 12" x 15"tall tank is one ph running constant, and 2 others alternating off of a Natural Wave timer. Anyone have any tips for getting some decent 'wave' action and ensuring as few dead spots as possible?
