I have a 55gal with a reef lake wet/dry and a whisper 60. I am pumping the water back from the wet/dry with a rio hf17 water pump with about 5 feet of hose. The water current seems to be really strong for the fish and plants I am going to guess about 5 to 6 hundred gallons per hour. I use an eheim spraybar at one end of the tank opposite the overflow. Should I place the spraybar in the middle of the tank to spread water thru the whole tank or leave it. It just seems to me that the current is too strong and if I direct the bar up water shoots out of the tank If I point it doun it uproots my plants what could I do to keep the flow without too much current

you could double the spraybar (using a T-fitting) along the full back of the tank. Or you could increase the number or size of the holes in the spraybar. If your turnover is really on the order of several hundred gallons an hour, you may need to both.
There is a huge difference in speed and total flow. You are trying to reduce the speed while maintaining flow, so you need larger cross-sectional area of the return paths. Doubling the bar will cut the speed about in half. Doubling the number of holes at the same size will cut it in half again. Increasing the size of the will cut it by the relationship between the original hole size in area, and that of the enlarged holes. Doubling the diameter cuts the sreed by ~four.

That's the same one I have, you can just order the pieces from eheim. You don't have to buy the whole "spray bar" package again. Look at the instructions that came with it, it'll have order #'s on it and the pieces you are looking for.syntax357 said:
