OK, so I never bought a system last summer as I had to add on 500 sq ft of living area by myself and that about killed me. No time for this system and I ran out of fall and still have some construction.

That said I now have the time to read and study and the more I do the more info I soak up the more confused I seem to get by different views.

I think I will buy from this guy on ebay and this system has a THOMAS COLORITE pump but he also sells the GAST. If the GAST is that much better, I will step up and buy it but I keep reading that the THOMAS is fine?

Thats said, now I need to know which disc diffusers from this company which seems affordable. I would like to get a better understanding on how many of the 12 or 9 inch diffusers this system on ebay will push CORRECTLY. And is more better for the pond I have listed in the post.

I dont have any issue spending a little more the GAST. I dont see a point in spending huge money for the VERTEX discs if these will work and I have no issue building my own stands ect.

Im trying to get this done and 100 or so trees this spring summer, then the following spring it will be a new home build right on the edge of the pond!!!!!! cant wait
