Are I-tech skimmers originally came with hydrofoamer pump? They mount it without stand? I ask because i have 9420 model. Love that pump, lots of air, low watts, just wish that someone make proper stand for it(tunze?, i keep mine on rubber sheet..
The guy u got it from is correct. These skimmers are very well built. It needs to break in for a few days. I would leave the skimmer cup off for a few days while it's breaking in. The water level should sit right above the exit hole. I'd say about a 1/4 of an inch above the T PVC. If u take a mesh bag like the ones u would use for a media bag and ziptie it around the exit line it will reduce the micro bubble a lot to even zero.
My itech is extremely efficient that if it was off for a few days then it would take a few hours even a day to break its self back in. I would have to usually open the valve all the way and let it run for a while till I could dial it in again.
Ur skimmer is going nuts cause there's a lot of proteins and excessive nutrients in the water column and with the combination of the skimmer still being smooth and clean inside the bubble just shoot up out the top. I'd even say put it at the proper level and put a air line needle valve at the Venturi inlet and limit the amount of air the skimmer will draw in. Then let it run like that for a week at minimum. After the skimmer breaks in let it take in all the air it wants.
These are great skimmers. I love my 200 and wish I could find a 400.
Hey, thanks for the response.
I took a video of what I'm seeing.
I just really can't think this is normal and it'll just even out over time.
Hopefully I'm wrong?

Also can u get a pic of the tunze venture also? I've got a feeling maybe it's been modified and it's sucking in way to much water and not enough air.
Now i want to modify mine too. How old is your tunze? They had different models before, newer suck more air and less water.
Did you measure air draw with larger inlet?
As always, THANK YOU for the support.
