Cheapest place to buy new vortech mp10?

[phyto4life]

Thanks

I can't wait to get it

one last question it is for my brother in law

he has a 90G and was thinking of going sps and buying 1 x mp40 for now with only a few tiny frags and another later is this ok?

or would 2 x mp20 do in the long run?

he has no closed loop only a 800 to 1000 gph lift pump and could add 2 hydor koraila 4's with the vortech's
