Hello,
I've recently posted several threads regarding coral issues, particularly their failure to open due to flow concerns and other factors.
After some experimentation, I've managed to find a wavemaker position that allows my corals to open up. I adjusted the angle of my Nero 3, directing it towards the surface, and simultaneously lowered the gallons per hour (GPH) of my return flow. To address some death spots, I also increased the intensity of the Nero 3. Now, everything seems to be running smoothly. My GSP is thriving with the additional flow, and the zoas are responding positively. While my hammer coral is doing well, the torch coral hasn't fully opened yet.
In my efforts to understand the concept of total turnover better, I find myself a bit confused.
My tank currently hosts soft and LSP corals, and the general recommendation is 30X total turnover. Accordingly, I've reduced my return pump to 150 GPH (down from 185 GPH), following the idea that 10X turnover in the filter chambers works optimally.
This adjustment leaves me with 20X turnover to allocate. However, setting my Nero 3 to just 1% already exceeds that limit.
At present, my Nero 3 operates at approximately 1000 GPH, and my corals seem to thrive under these conditions. There are no death spots, and the water movement from both sides is substantial. However, this setup puts my total turnover at 76X.
Am I overlooking something, or is this approach too extreme? Any insights would be greatly appreciated.
