Did anyone bought those powerheads ? I have 2 now and i'm not supposed to put them very deep . They're very powerfull but i wanna have one completely underwater where it's needed...at the top, there is already the skimmer and a filter creating a lot of water movement. Did someone tried to submerge one successfully for a long time ?
Is the warning on it just for scaring me ;-) ?
