The Johnson pump model CMP30 is actually more powerfull than the 1048 and 1250, by Eheim.
Maybe he thought it was the Johnson model# 10, and I'd agree, in that case.

I should state that all I knew about the pump was Solarian League's statement of "1.5PSI and 7gpm". I never knew the model.
The Eheim 1046 pushes around 1.7PSI, the Eheim 1048 pushes about 2.3PSI, and the Eheim 1250 almost 3PSI.
I was basing my response on that a pump equivalent to an Eheim 1046 is about as low of a pumping pressure that I would recommend otherwise it might be more prudent to consider something like the White Water, and a figure of 1.5PSI was quoted to me.
