Hello all! New here at reef 2 reef and just bought a 60 gallon cube with a 20 gallon sump. I do have minimal experience with reef tanks as I have a 25 AIO nano that’s been up for a year. I am expanding to a 60 gallon cube with a sump and I have no experience with sumps. The tank is top drilled for both intake and return. I am having issues with the sump as when I turn my pump speed up it gurgles and bubbles a lot down in the sump. What is the cause of this and how can I prevent this? Do I just need to run my pump at the lowest speed and use power heads to circulate the water? I did add some tubing for air intake thinking that it would mimic a durso drain but didn’t help much!
Thanks in advance for the advise!
