New setup skimmer overflowing week 6
 

Hi, i recently started a new setup using a small amount of my old live rock from my cube and 80% marco rock, i have a swc 250a1 cone that has been overflowing since day 1. I tried letting it overflow in 5g bucket for 20 gallon to try and remove whatever is in the water. I haven't used chemicals or epoxy.
Skimmer is sitting in 6.5" of water valve is fully open I'm not new to this so i was curious to know if any one has experienced this.

When i replace the water that i skim out (5g x 4 times now) it settles for 45 min but then its starts overflowing again!

Any ideA's?
Thanks

Have you checked the air intake to ensure its not blocked? My last new skimmer had some packing insulation fall in the intake. Are you using ro water? I had a issue with tap water and my bubble king never went away till I went to ro water. I assume you have the outlet open all the way.

Are you using any filter floss in your sump. I found this can also make simmers go nuts

not blocket, ro/di at 0 tds and yes the outlet is fully open. could it be cause of the marco rock.. ?

I've never had any skimmer issues using marko rock. Have you tried cleaning the skimmer body out with vinegar?

after 6 weeks in the tank ? i dont know if it will do anything othen then kill the slime no?

Platics and O-rings sometimes have an oil on them that is typically water proof, worth a shot if you are still having issues after 6 weeks. Have you tried contacting SWC directly to see what they suggest?

im kinda sure its the water chemistry, if i put my hand in the tank for a bit it stop overflowing and actually goes down 4" under the neck. but then it come back. right now its not overflowing by much... i guess either patience or waterchange.. im il be doing another bigger one this weekend..

My alk got low in my tank because my doser was slipping and my skimmer was overflowing a bit till I got it back up.

I think this is from our skin oils my bubble king takes hours to get the head back after I reach in the tank.

Are you running carbon? Another thought is my skimmer had a ozone port I never noticed and was always overflowing so I only ran 1 pump then I figured out the hole had to be plugged.
