 pump for 180gal 16ft high
Ok here is a fun one.
My new house is almost built so the 180gal is finishing it's plan.
I will be putting the 75gal fuge in the basement flowing up to the 180 on the first floor. The 180 will have the dual built in magna flows. (i'm estimating about 16ft straight up between the 2 tanks
Questions
1) Should i get one single pump and split it for both returns or get 2 different pumps which will help for redundancy (if 1 or 2 i will be doing a small split on a ball valve to cycle water directly back to the fuge so that I can keep it running at full and also use it to water changes / breeding tanks.)
2) A good recommendation on some pumps for the job. I am not planning to plumb the 75gal fuge so my options are to do an inwater pump / pumps or external that allows me to mount it above the tank somehow and have the intake going through pvc first.
Thanks again for your expert advise.
