Hi Mike i like your air driven skimmer and I have seen it in action works great. I don't think I will give up my Aqua Medic though as It works extreemly well for me.
So that air pump is working better for you?

Yes, the larger air pump makes a noticeable difference, especially since I purchased a plank of basswood and built my own wooden air diffuser. It's much larger than anything you can buy and since all four sides produce bubbles, way more efficient. I had to put a small rock inside it to help weigh it down, but it still wants to float. Meant to take a photo after gluing it together, but didn't.

I also have a remora and it's awesome. Upgraded from a coralife which i thought is a bit too loud.

can you get some of the rubber coated lead weights wher you are. that maybe heavy enough. Being rubber coated it will not leach in to the tank. Also good to hear the air pump works well for you.

One note about the remora C pro, It is noisy.

There is a Deltec HOB for sale in the buy/sell section. Good price for brand new.
