We have a fairly new 62 tideline and overall we love the tank. The dual shadow wave return nozzles do not work well, if at all. I am pretty sure the pumps are underpowered at 250 gph as well. Has anyone replaced the nozzles with loc-line? I would probably swap the pumps for mighty jets as I have one on my 32 and really like it. I am not even sure what size bulkhead we would need for the nozzle. Hoping someone here has done this and can help.
