manifold? Good or bad idea?

[aiko670]

from left to right.... this will be for a 120 sps tank.

Spare, Calcium Reactor, Carbon, Phosban reactor, main line to scwd, remote fuge, ASM G3 skimmer with recirc mod, chiller

the sump is a 40 breeder that will reside below the tank and the fuge will be a 20gal long on a shelf above the tank.

I'm planning on using a mag 18. The CA reactor, carbon and phosban reactor will just be trickling so hopefully it will be strong enough.

As for circulating the tank I have a Sequence Baracuda that will be going to an Oceans motions 4way. I chose a Baracuda because it will reside in my crawl space and I wanted to account for head loss. If it's too strong I'll just throttle it back...

So what ya think?

Thanks
Adam

I think you will need a bigger pump
say like a panworld 200 or something pressure rated

 

[aiko670]

Argh, it needs to be in the sump....

I guess I could drill the 40 and plumb that down to the crawl too but I'd rather not if I don't have to.

looks like a cool design but I think you would end up external adventually
better pump longer life span more reliable but if your going to try a mag go with like the biggest you can fit

either pump can work I guess but I personally believe the panworld will last longer

Gonna need a much bigger pump to handle the back pressure. I would also make the single feed line larger to help cut down on the pressure.

If you must use a Mag for this, increase your output line by atleast 1/4" - IME mags run better when benefitting from lower initial pressure (I have a mag 9 that runs so much cooler and with better flow after I switched the output plumbing to 1" from 3/4").

I hope you haven't glued that. I did something similar and wasted a lot of money on it. You will need a very large pump. Like your Baracuda. I love the idea, just didn't work for me. If you need a hole saw to drill your 40 let me know. I have then for 1", 1.5", and 2"...Rod also drills tanks.

You'll need a waaaay bigger pump.

Here's what I have:

I feed this with a Mag18 against some head pressure though and it's just enough for these 3 chambers.

The problem I see with mine is no visibility into actual flow rates through individual chambers. And flow meters are incredibly expensive. So you're left with either eyeballing flow or measuring how fast it fills up a bucket.

It's a great concept and mine works great for my needs, but with so many on yours, you will need a lot more pump to make it work.

 

[mhurley]

Oh and one more thing...I now have that 3rd chamber filled and there is definitely just barely enough flow through my system.

 

[aiko670]

OK, a bigger pump it is then.......

anyone want to buy a mag 18 with less than 1mo use?

 

[whiirly]

how much for the Mag?

 

[aiko670]

$75 sound fair?

My buddy and i setup a friends 125g and decided to use a manifold to make life a little easier for him...were using a Reeflo Dart...(thanks to DD for the pump sale)...working out quite nicely....this pump does 3600gph at "0"ft...were at 4ft and probably doing close to 2500gph....

HTH.

Thanks for all the advice everyone!

Racenrich - that's a nice manifold. The use of tubing decreases the friction on the water. Great idea.

thanks...its my friends setup...i told him we need to put some flex pvc...then no chance of algea buildup...
