So, say I don't have any way to add a closed loop right now. I don't have $400 to spend on a wavemaker, I don't have $135 to spend on a jaebo wp40 or whatnot. (I know you're thinking, I'm in the wrong hobby!) hahaha I spent 20 or 30 bucks on two maxijet 1200s w/ eco mod. I "think" they are good flow. I pointed them pretty much to meet in the middle of the tank. They chatter and occasionally fall off. I can live with the chatter, the falling off is unacceptable to me. IS there anything else that would be better than suction cups and hooks? Thanks!
