pump options

motojoe1988 · 04/24/2013, 01:23 PM

So I have a 36x36x22 cube yet to be up and running yet. Hopefully this weekend! Anyways I went ahead and bought a new pump for my tank since my current tank is still up.. I bought a rio hyperflow 32h I believe. So ill be running 4 returns off this pump through a manifold but cant decide if I will be happy with it. The pump pushs abt 1900gph with 0 head. I was doing more searching and came across the laguna max flow 4200gph. Now thats the flow I want since im going for a no powerhead tank due to a all anemone tank and lps. Now the tricky question is my pump rio 32h is still nib and I think 1" outlet. The laguna is a 4200gph with a 1.5" outlet. Question would be can I make a 1.5" manifold and downsize into the returns that are 3/4". Will the downsize effect my flow rate dramatically? Im thinking the 3/4" would only be about 1' long to the drilled returns from the manifold. I guess my question is should I sell curent pump and buy the laguna? Will 1.5" be able to be downsized to 3/4"? Thanks

Any laguna max flow users? How do you like the pump? Did you downsize the outlet? If so to what size?

Two things to consider here.
1. Can your drain system handle the flow?
2. Restricting the return size will decrease the flow considerably.

My cube of the same size was run off an Eheim 1262.
Perfect amount of flow through the sump and my drain was a 1" Herbie setup with a single return line that was split at the top where it re-entered the tank.
I know you are running 4 returns, but just posting for comparison sake. Not sure if it helps much but there ya go.

Well I have 2 1.5" drains 1 for emergency so 1 will be full siphon. I wouldent mind the flow restrictions as much from down sizing to 3/4" considering I still have a decent amount of flow. What do you think would be a better option 4200 or 2900? Thanks for the replies

Take a look at the Water Blaster pumps. I am running one on my 50g cube. I could not be happier bout my pump choice

sirreal63 · 04/25/2013, 01:33 PM

The problem is I have no way of knowing how much loss you will get by restricting the pump that much. These are not pressure rated pumps so you will lose a lot of flow with that much restriction. You would be better of from a flow standpoint to just use a small powerhead in the tank with broad gentle flow than trying to get all of your flow from the return.

Im trying to avoid all powerheads!!

I agree with sirreal63... can your overflow handle that much? Otherwise you'll just pump water till the sump runs dry and the display overflows... It sounds almost like you're trying to combine your overflow as a closed loop?

sirreal63 · 04/25/2013, 01:59 PM

I understand that but keep in mind it may not work out the way you want. Too little flow is far worse than too much. Anemones need excellent water qualityt, a lack of flow can present water quality issues. If you expect the return pump to provide the most flow it can, you will need to change the plumbing to reduce as much friction and head loss as possible.

motojoe1988 · 04/25/2013, 03:04 PM

Im not sure of the gph a 1.5" can handle under full siphon (herbie). Im not trying to do a closed loop. I just want a powerfull return pump! As for changing the plumbing that will not be possible as the tank is already drilled. The return will be ran through a manifold about 3' long. So there will be tees.unions.elbows. and reduced to 3/4" so im consider the big loss of flow there aswell so im sure ill lose a significant amount of flow whixh is why im considering the 4200gph laguna

motojoe1988 · 04/25/2013, 05:22 PM

The manifold will be a 1.5" then reduced to 3/4"
