Need some help with new tank

Try upping the size of the tube you have coming from your pump when you get to the bulkhead use fitting to pipe it down to the size that fits the bulkhead and then run that the rest of the way up into the tank display. And honestly I would buy a better pump but that's just me:)

I'm guessing you went from 1/2 up to 3/4?ÂÂ

We actually went up to 1" I'm running the pump at one below full but that's because I have a ton of coral in my tank and big colonies so you wouldn't need to run it that high unless you're really stocked like mine.

The physical engineering of moving water through pipes shows us that 1 inch piping is the most efficient for the volume of water flow of these aquariums. 1/2" pipe is extremely restrictive to water flow. Larger piping is especially important for the drain plumbing. Also, the flat(fan) nozzles are counter-productive to flow. They actually disperse the flow, making it less effective. Their real advantage is in dispersing overly strong flow which, depending on nozzle positioning, might otherwise blow the sand around. Instead of the fan nozzle, I often simply remove the end jet nozzle piece. I position return nozzles so they goose-neck down and back up, shooting water up along the surface to create a rippling effect. This more effectively oxygenates the water, also allowing CO2 to leave the water. More O2 in the water makes breathing easier for all the animals. Less CO2 in the water ensures good, elevated pH making the whole tank healthier. Here's my last tip and then I'll shut up. Positioning the end of the return nozzle at the same elevation as the overflow teeth ensures that a siphon won't start which could flood the sump in the event of a power outage. Check the backflow of water by setting everything up and running, then turning off the return pump. Watch to see if the sump can hold all the water that drains down. If it looks like it's about to overflow, quickly turn on the return pump and then re-position the return nozzles. (Sometimes this means we have to run the sump with less water, at a lower level.)

This all great advice and i very much appreciate it. Thank you.
