On my soon to be high tec planted tank, I'M using a Rena filter, should I use the spray bar or jet nozzle .........Also should I have The return skim the top of The water or point it away from the top, more towards the middle of the tank ? little confused on this. Thanks Rob
Personally I would use the Jet nozzle I have found that spray bars never seem to work well. Also I like that the Jet Nozzle helps to circulate things around the tank better so more stuff makes it to your filter inlet pipe.
I agree with the above. I dislike spray bars as they always seem to need more maintenance. The holes stop up. The water level is always getting off so they make noise or if placed wrong they can shoot water over the side when the tank gets a bit low. This only happens when I'm gone and a neighbor is watching the tank!
I just don't use them as they do reduce the strong flow around the tank which I prefer.
I would not want the return drawing from the top as it might come out of the water if the tank level went down. This would cut off all filtering to my fish as well as potentially running the filter dry to ruin it.
