...it won't ever work the other way around. You won't ever be able to make the fuge have LOWER water level than the sump. You probably wouldn't want that anyway!

No I would not. Wasn't really thinking of doing that either...just trying to say with the gate valve I get more control over the water levels!

Well most of the plumbing is just about done. I will post pics when I have a chance. I have a question though...

My closed loop is mostly dry fitted but I still am not sure about how to do the outputs. I am thinking of just using 2" 90's or 45's that are not cemented so that they can be pointed in most any direction. Any one have any reasons I should nto do it this way. Besides the extra cost, I do not want to use lock line because its output is too small. The other problem I have though is the Eurobracing getting in the way but I think I can work around that. Any thoughts?

My 75 has the outputs as non-glued in 90's off a T. Low tech, but it works fine. 5 years in now..

I find Locline isn't all that restrictive though .. I guess the one counter argument is that if you do find it too restrictive, you can add more outputs (via T's) and then you have more flow-aiming options.. And it should be easy to work it around the Eurobracing. Just a thought.

How easy is it to go from 2" T's to loc line though? What is involved? I have never used loc line before actually.

What fittings would I need? For example, I see only 3/4" loc line on J&L's site. Would this even be big enough? I do agree, I could add more T's and that would actually be pretty good.

Would I basically have to use PVC fittings to reduce down from 2" to 3/4" and then use a 3/4" Modular Piping MPT Connector Fitting (threaded) and then the loc line and then whatever nozzle? Sound about right or is there a better way?

Nevermind. I just figured out what I would need to spend to do this right with Loc line and I cannot spend that much more on this tank right now. Its like close to $200 for just the loc line fittings for all my outlets and thats without any PVC fitting I would need! So probably like $225-250...Not happening! I added up everything the other day and Im at about $2000 now...Thats ontop of all the stuff I already had. Thats actually not so much for a tank of course but this was suppose to be a cheaper one! Especially being a FOWLR.

You need a bushing to go from 2" to 3/4" threaded (NPT or whatever it's called) and then the Locline just threads into that.

Sorry, I didn't realize your returns are 2", that is quite a size reduction. Although you could think about having more outputs I suppose. You could either plumb additional outputs with the pipe, or you could use Locline Y adapters (e.g., http://www.jlaquatics.com/phpstore/s...t_ID=pl-mp034y )

I was editing my post while you wrote this one...Its pretty much out of the question. Im at 8 outlets now and the cost would be far too much. I really just don't like being able to see the 2" 45's coming down into the tank but oh well, for now they will have to do I guess...
