HI all, I have a couple of questions about powerheads.
Are their electrical cords submersible? Is there a rule for powerhead flow rate (like the rules for lighting - wpg, or for filtration - gph)? If so, what is that rule, and which flow rate would be best for my tank (75G, 48x18x20)? (I'll have an XP3 filter in that tank that pumps 350 gph.) Now, if I will have a filter that pumps 350 gph - shouldn't I also get a powerhead that pumps 350 gph? Or is the rule dependent on something else (if there is a rule)? Lastly, are there any powerheads with adjustable flow rates, or you just get what you get?
Thanks for help up front.
