powerhead ?

How many gph should a 29g tank have?

 

[kevin4052002]

I would go somewhere around 600gph, if you are using a single SEIO or Tunze. With Maxi-Jets or the like, go for something like 3 MJ1200s.

I like flow.

stickies are very helpful

It depends on what the tank houses. If you have a fish only with live rock tank you could get by with 300-450gph imo but if you have coral you would want more flow.

Shoot for 5 to 10 times and read the flow sticky

 

[aresgod]

I would shoot for more than that, I have 20X, and I feel like I am lacking, anyone who goes to a reef will realize how little flow we actually have in our tanks comparatively.

 

[Flowerkid]

really 600 gph i read the sticky but i want a reef tank. Really 600? wow

 

[kevin4052002]

More, if you want...hehehe...

 

[Igor The Cat]

600 isnt really that much, its how much i got in my 10gal fresh lol, but just for fun i put ~3000GPH on my 29.....its very fun to see the medium size rocks rolling around lol

cheers

I just set up my new 20g w/15g sump and in my main tank (20g) I have approx 995 gph... it all depends on your rock work and how much it disrups the flow.

In my old 29 I had one Seio 620, the flow was good but couldve used another powerhead on the other side to hit all dead spots.

As is usual with these stupid rules, the one saying you need 10times your tank volume in gph works much better in big tanks than for small. Basically you need to get decent flow everywhere, and in a small tank that might result in what seems like an excessively high gph.

Also it will be higher if you use powerheads than tunze/seios or closed loop returns as the flow from (narrow bore) powerheads dissipates so quickly

in my 10 I had about 500gph and it was way too low, cyano came in until I changed the placement of the powerheads.
For my 37 I just bought a seio 1100 and with the hob skimmer I am hoping that there will be good water movement. I suspect that I will have to get another powerhead.
Just don't underestimate how much flow is needed.

 

[Flowerkid]

would 2 400gph powerheads work?

 

[amd]

should be fine, i would recommend 3 smaller ones over less, more pwerfull ones... i think its easer to not have dead spots with more pionts of origin of current, but thats me

i have a 12 gallon nano with 2 300 gph p.h. and 1 400 gph and a 275 gph
the 400 runs my intank sump/skimmer

 

[Mushroomman]

I had a seio 620in a 29g, it put out some flow, but I wanted more, like an additional 820- you dont want any dead spots and you want water to circulate as much as possible, aresgod speaks truth, our tanks are no where near real reef flow.

You could proabaly get away with that flow, but youre gonna find you might want more than that.
