Hello everyone, i'm new to the hobby... i had a small reef tank for about a year didn't do very well with coral but the fish did ok.... im hoping i can do better this time around. so anyhow im new to sumps/overflows/skimmers/socks and just purchased a reef octopus 110 internal protein skimmer.Well the directionbut s weren't the best but i managed to peace it together kinda easy(got a couple spare parts donno what to do with them) anyways i cranked it on and it filled the collection cup with water in about a minute.. so turned it off and went to home depot and bought some parts to raise it becouse the recommended water level is 7-8 in deep but my sump runs closer to 10 1/4 in deep so got the water level to about 7 1/2 inch... cranked it on again this time took a bitt longer but still filled with water. so theres a drain plug on the collection cup i opened the drain so i can run the skimmer and break it in... but i feel like im doing something wrong still. it has one adjustment i can see its a knob for the water flowing out the pipe i got it open all the way i tried chocking it back but it seemed to make the skimmer fill up faster with water any advise would help ill try and post some pics... oh its a 75g tank with a 20g trigger system sump... im running 2 power heads and a bag of carbon and a sock currently.. no heater yet. 1.023 salinity... about 50 pounds of dry pukani and about 10 pounds of dry sand. amonia reads around .7ppm.. planning on doing a 90% water change once amonia drops i know its dirty. didnt clean rock first. also i put some seachem seed bactiria and a damsel in tank last week.... the damsel didnt make it but i left it in my sump couse ive heard of people using dead shrimp to help cycle the tank so figured wouldnt hurt... i didnt put him in a stalking though. also if i dont choke back my return pump my overflow gargles a lot and i get a lot of foam in my sock i think i bought to strong a return?
