might need a bigger pump?

The pump might have been undersized from the beginning? I have a closed loop on the one side of the frag tank with a mag 18, and a k4, and 2 k4s in the other side.

I do have the frag tank and 29g throttled way back (maybe ball valve open 20% on 29g and 40% on frag tank.

I just keep visualizing spitting water out of a straw with little holes on the side before the bigger one on top. More pressure = more water comes out of the closer small holes before it can get to the large hole on top.

if the top dt tank is say getting 600gph down the drain and up the return and the bottom tanks are getting 1200gph, i would think that the overall water quality would be better dwonstairs (even though the same water) just do to it staying in the dt where i feed more, more fish, etc..???

It could equate to more detritus in those tanks yes. But one thing to remember, although it seems as if more water is coming out of the smaller opening it actually is not . It is coming out at a higher velocity but the actual amount of water coming out is less. Think pressure washer usage or an open spigot in terms of volume.

that is why i was thinking that the more water that goes in the DT, the more detritus that gets drained down to sump/skimmer...

Only if it is suspended long enough to make it to the overflow and with the proper amount of flow combined that should do it.

Edit: Even if it gets to the sump quicker I'm not sure what benefit that is if it doesn't enter the skimmer any quicker. May be advantageous for removal be filter socks or floss.
 
Talked to the reeflo people and i am getting the mod to make the wahoo a barricuda? I think.. that shouadd about 400-600 more gph by itself. The real help which will bump it more than double/triple is that ill be increasing the return from 3/4" to, mostly, 1.25"... also, chris installed the true unions backwards (has arrow that says flow going wrong way) although im not sure if that reall matters?
 
Whats the mod?!

Your current return line is 3/4" from the pump to the tank? Someone should've told ya to get adapters and step up to 1.5 as quick as possible on the return.

The ball valve in backwards would not impede flow but the 3/4" would :eek:

Not sure it matters since none are 3/4" outlets.:D

That arrow doesn't indicate flow - it is only for upgrading the valve to an actuator.
A very wise man told me...

(look inside a valve and then turn it around - looks exactly the same way...)

Yeh, it was 3/4 coming out of the pump so he stuck with that... prob going 1.25 " due to not wanting to have it bigger than the input side of pump..

Interesting (impeller).

Yeah, stepping up should GREATLY increase your flow. Of course it means you have some plumbing to do :p
 
Not aware that the Wahoo is upgradeable,

but Snapper -> Dart are
and Barracuda -> Hammerhead
 
Yup.. i dont want to have to redo it again.. do ya'll think 1.25 is enough? I was planning on running that from the pump up at least 10'(to the top of basement ceiling)(maybe another 2' or so more til return splits) and keep the "ends" of the return line 3/4..
Not redoing thpump intake at all which is 1.25 as well..

Edit: Yup. I was suprised too. I might have gotton the name of what pump it becomes, but im pretty sure she said barracuda? She knew her stuff though..
 
I think if you check the performance curves of the one you have and the 1750 turbo sea you might get what you want from it which is seal less. Although it sounds as if you have a fix.. If you have a lot of turns up to the DT 2" pipe will help even more.
Going bigger than the intake will not be an issue for you with all the head pressure you have. Cavitation should never be a problem for you.
