Need Help on Height of Sump

[EnglishRebel]

Okay I'm fitting out my basement equipment room and need some advice. I will have a refugium and a sum both fed from the DT. The refugium will gravity feed to the sump. I will be building the supports for both shortly and would like your opinion on what the best height for the top of the refugium and the sump. The fuge will be about 18" deep and the sump will be about 13" deep. I need to construct the shelves for these at the right height and want to ensure that I can service both. It would seem that the sump should be the lowest so if I locate the shelf at say 24" off the floor then the top would be at 37" above the floor. If the fuge gravity feeds to the sump then the top of it should be about 55" (the fuge bulkhead is about 4" below the rim so this allows about a 4" drop from the bulkhead to the top of the sump).
Does this seem like a suitable configuration or does someone have a better idea?
Thanks.

Hey, you can make it simpler by building a sump/refug, then you only need one hight and one shelf. I have a pic of my 30 gal sump refug which is all diy with recycled tank and glass

How does BooBoo feel about this?

will the sump overflow from the fuge if the power goes out.

Seriously though as far as the original topic here. You didn't really specify but I'm assuming the main overflow from the tank would feed the fuge which you want to gravity feed to the sump. So if thats the case you can not regulate the flow to the fuge so if you were running 1500gph that means your fuge is seeing 1500gph... which is probably a little too much flow (depending obviously on what you are using your fuge for)

You could still build a shelf and place the fuge above the sump and have it gravity feed to the sump but you might consider running a PVC wye (a less restrictive T) and use a gate valve to control the flow to the fuge and have the other end feed the sump directly. I would just spend a lot of time considering your overflow protection in the event of a power outage as mentioned above, if everything eventually gravity feeds to the sump you don't want it to overflow with the water in the lines, main overflow and fuge overflow, you might want to go with a bigger sump.
