So I just set up my sump, I have 1 h2overflow with stealth box as my intake i plumbed it with a gate valve to adjust it, I bought a dc pump rated for 1200 gph, but no matter how many adjustments I make to either the water level in my aquarium or sump raises and doesn’t level out, I cannot find anything online about how to fix this and I have been sitting at my sump adjusting it all day so it doesn’t overflow, please help
