Hi Vin, haven't talked to you in a while.
I ordered the Sequence from AZ Ponds and made it a special order to get the saltwater seals. It also will be pumping from my basement. Because it's a closed loop I figure the only head loss is from the friction in the pipes. Hopefully no elbows until I hit the top of the tank and it's 1.5 inch piping all the way. So, I think there will still be a lot of flow and with only two outlets on the 8-way getting water at a time it might be too much. I'll have to think about having perhaps 4 at a time, maybe in circuit like 1-2&5-6, 2-3&6-7, 3-4&7-8 etc. I know I can throttle the pump back if I need to but I don't think it's good for the pump to pull it back too much.
I'm also looking at the wave2K, which is pretty interesting and doesn't need to much plumbing.
Planning my new tank is certainly taking a lot of time and i'm learning a whole lot. I guess getting there really is half the fun.
