Hi, I have a 120 SPS only tank and changed to Tunze 6105 pumps and put wide nozzle on, it is set to blow gently over the corals on Sequence 2 30% one, 100% other and I rotate it about 7 second cycle.
I would like to go back to narrow nozzle, but it really blows the sand around, I am thinking of sucking all of sand out in front and go bare bottom. Any opinions, there is not much there, less than one inch, but under rocks about 1 to 2 inches and I would leave that in place.
