Plumbing thoughts and suggestions

[Seitzjh]

I have 224gal with 2 corner overflow with 2 bulkheads in each. This sketch is what I'm thinking of doing. Still in a very long setup stage and taking my time. My plan is to add 2 mandarins when tank is mature and I have a good population. Can this work to keep a high population to feed them without going out and buying pods after first purchase?

It's difficult/impossible to predict pod population other than the basic idea that bigger is better, plus plenty of time to mature, to at least give a healthy population a statistical chance, as you have noted in your plans.

I'd go for as big a refugium as you can, and find a way to flow them back w/out getting ripped through a pump. With mandarins, that still won't be a guarantee. However, a 224 with two 'fuges is an awfully good start. Good luck, and it will be great to see your build thread.

I'm not sure if I am reading your diagram correctly but if you don't have gate valves on your two drain lines I would add one to each drain line. I would also add a third emergency drain line. You definitely want to have a second emergency drain line from the refugium/pod culture tank to the main sump line or you risk a flood if the main drain line were to get clogged.

I don't know if the bottom is tempered or not to add a third. The bottom glass is 3/4". Yes. The true unions are going to be ball valves on return and drain.

How about this?

It seems like you have a lot more valves than necessary. Also do yourself a favor and use gate valves wherever the valve is to be used for flow control. Ball valves are great where you want either full on or full off, but gate valves are MUCH easier to use where you need to fine tune the water flow.

I have 2 corner over flows with (2) 1" bulks in each on a 224gal. What size pvc on drain in tank should I use? I'm doing 1" return. and how should I set plumbing (1) 1 1/2" Durso drain on each side and 1 return on each side then reduce to 1"? Any suggestions. I'm not sure if 3/4" bottom is temperd. As of right now my plan is to do the second diagram in thread. Yes some ball valves in diagram will be change to gate for dialing in.

Sorry I just saw your profile post...I don't get an email notification of those so anytime someone posts on there, I miss it completely...vBulletin sux.

Anyways, I'm not sure how much help I can be. The 1" BH is going to restrict a bit, the bigger the drain pipe the more flow it can handle at full siphon, but you're probably not doing that here. Bigger pipes generally have a little better flow characteristics though but I suppose the main question is how much flow do you want to have? There's going to be an upper limit probably due to due 1" BH.

If its 2x 1" bulkheads in each overflow and the bottom is tempered your stuck. Just use all of them for drains and go over the side with your returns

 

[Seitzjh]

there is a total of 4 bulkheads 1". I don't now if I should just do 2 durso 1 1/2" then bush then down to 1" at BH? or that is another thought return back over and maybe herbie on each side. but I don't know if sump would be able to handle the water on power loss.
