Foam in refugium

[Sunshine]

My 90 gallon tank has been running for 4 days now. I am getting a lot of foam in the refugium and air bubbles in the tank. Is this normal ? The water level went down in the pump part of the filter, I added more water. Here are some pics. Hard to see the air bubbles in the tank. We haven't got the skimmer yet, still on back order.

Do you have your protein skimmer in the refugium, thats where the foam and bubbles could be coming from.

That is a lot of foam.
I dont know why your getting that much in your fuge,but if you'll raise the water level in the return compartment to almost the top of the last baffle,it should stop the bubbles from making it back to your display.

i noticed i had a foam building up on the water line in my sump from a lack of flow so increase that and see what happens

Thanks, I'll raise the water and see if that helps. The flow ? I have a 950 gph pump. The intake I slowed down cause it was gushing pretty hard. Should I let it go in the refugium faster ?

I dont think that increasing the flow throu will help much as far as the bubbles getting back to the display.But raising the water level in the return to the the top of tha baffle will should get the bubbles away from the pump.

to stop all the foam i would try putting an 90 elbow on it so its sitting halfway in the water and halfway out so air can get out and i think that will fix the foam part.

lay a piece of filter pad over the return baffle that will help hold it in place with a piece of rock or a plastic cloths pin

Well, I raised the water level. It looks better in the tank, still some tiny bubbles, but, not near as bad as it was. As for the foam, it's still there. I'll work on that.
Thanks for the help...... :)
