Ca reactor pump size

[harper]

Whats the logic behind the sizing of calcium reactor recirculating pumps? I purchased a seltz CM202 calcium reactor, and it turned out the recirculating pump is seized. I can plumb in just about anything or maybe get a replacement from over seas. But I'm wondering if it needs anything nearly as large as the OEM pump. The OEM is 4200LPH/1100gph. I see similar sized units from octopus have varios 6 pumps.

My guess is that these big pumps would be needed if using fine crushed coral. But with ARM extra course media can one get by with a much smaller recirculating pump? Maybe it would be an issue over time as the media dissolves and compacts?

Any recommendation on replacement pumps? The OEM would fit well but a dc pump would be nice. Plus I would like to plumb in a pump commonly available pump. I am looking at the platinum blue 800. Maybe a jebao, model recommendation? I have a IM mini jet on the shelf, it's only rated for ~300gph, I'm wondering if that would do the job if I use ARM extra course media?

Thanks for any input!
