Hi All, My 35 Tall Tanks keeps showing signs of low movement water/stagnancy near the bottom. Right now the return of the water is by spraybar at the surface of the tank. I suspect that the spray bar movement at the top is leaving the lower regions of the tank kinda stale. What does one do to change that? I bet there is some sort of piece of gear to buy or something. Please advise. Thanks Shango _______________________________________________ GSAS-Member mailing list GSAS-Member@thekrib.com http://lists.thekrib.com/mailman/listinfo/gsas-member
