am i still allowed to suggest something? i'd love to see a 'workshop' on the diffrent types of flow.. i can never remeber the right names, and it seems like something thats always an afterthought. like raceways and how to 'work' random when you don't have controllable powerheads.. also how maybe some defintion type stuff to cover what we all think is high versus low.. i've recently seen how much 'random' flow really seems to make things happier in the tank when i added a wp40. you also hear a lot of the 'increase flow' responses to algae threads, and i wonder if folks realize how important it actually can be. i mean, with a couple of powerheads, some food dye possibly, and a small tank, it seems like a LOT could be illustrated... and it also seems like this would hit the 'new folks', because it seems like we almost all start out with not enough, or powerheads placed randomly around the tank in an effort to find something that seems right...
