Water pumps?(for calcium reactor experts)
 

The more I look around the more I see diferent pumps being used for roughly the same size calcium reactors. I see Mag2's then I see mag7's. What in your opinion is the ideal pump size and what advantages or disadvantages are there for a smaller or bigger pump?

I'm using a mag7 on my huge reactor because that's what I had.

To give you an idea on the size of my reactor, it holds 5 containers of ARM.
so at 8 lbs each that's 40lbs of media.

THAT'S ONE BAD ASS REACTOR!!!!!

I use a MAG 2. I think it's more than enough to get a sufficient turnover in the reactor.

What's 'ARM'?

Don't know much about reactors.....but I will learn!

ARM is a brand of argonite reactor media.

I used a Mag 3 on my 24 tall x 4 in dia reactor. Building a rectangular one right now, 24x8x6 and I'll probably use the Mag 3 again (cuz I have it).

I use a mag 5 on mine.. I had it lying around and I wanted massive flow for the large water volume.

I use a Mag 7 on a 18" reactor.

I guess it depends on the particular reactor and plumbing. Trial and error and then you go buy a larger pump. Try out what you have first.

I have a Mag 7 on mine ... seems to work OK

Does the size impact performance? what would happen if the pump was too small for the reactor?

you might not be able to achive proper saturation and your output alkalinity will be lower than you want.
