what are the purple plumbing parts near the pump? also that black vat didnt come with all those bulkhead cut-outs right
They are the clear check valves so you can see what's going on inside.
I see you have an RO/DI Unit hanging on your wall Do you to have it set up to your sump or do you have it running to something else
ok on my ro/di i have it set up to fill that rubber maid can next to the sink for mixing up salt, also have it going to the wet/dry filter, i have valves at all the T'S on the RO line so i can cut any section off if necessary.
I like those smooth 90's. a lot less restrictive. I wish i used them on my setup.
I tried to use them as much as possible, and i also used oversized pipe on everything as well, like you said, to cut down on restriction, and have easy flow.
Don't use check valves on a reef tank or any other tank for that matter.
what kind of faliure are you talking about, I actually don't need them, if power does fail I have that 100 gallon sump, that i only keep half full, just for that reason, just one of those things we learn during the course of this hobby. I actually have them on there, cause i wanted to see the flow of water from my pump. But if the kind of failure you are talking about is that the flapper will come off and stop the flow of water, that would not be good. Something i will have to think about.
Keep the comments coming though, I appreciate it,
We are in the process of putting in the main tank right now, so I will have pics here in a couple of days.
