ASM Skimmer vs Euro-reef

[Ruth]

I love the G3 on my 230g but am going to be upgrading to a GX4. I have a G4 that I tried running for a week or so and did not find it as efficient as my G3. I may not have given it enough time but I pulled it out and put the G3 back in. I just found the G4 underpowered. I did order a new pump for it (Sedra 9000) but it will not fit without a mod of some sort that I am too challenged to figure out.
