I currently have a 125 gallon tank, with the sump pictured below. At the moment I have a HOB Skimmer on the side of the display tank also. In the sump I have two filter socks, marine pure block in the middle section, then the return pump.
I’m having water clarity problems and my ALK is high also. I know I need to use RO water as I just bought a unit and have it hooked up, but is there anything you would add to the sump or anywhere in general that could have a benefit for me and my tank?
Thank you
