Circulation Pump for 55 Gal Tank

[DragnX]

I need help choosing a Circulation Pump for a 55 gallon tank. It have terta and guppies in it and also cherry and ghost shrimp. This is planted tank. Thinking about getting two Hydor Koralia 425.

I have one koralia 425 on my 29 along with the sunsun 302canister. WWorks great for me. The koralia flow is nice. Not a jet. I bet that would work well for you.

I have 2 of the Koralia Nano 240s (one one each end) along with my Eheim ecco 2236.

To me, the flow is perfect. The plants sway gently and I get good flow in all corners of my tank.

Won't the open grid of the circulation pumps pose a danger to the shrimp?

I would think only for the tiniest babies. With my Korlias, the propeller is pretty small. I would think that it would be at least a 50/50 chance of them not even hitting the propeller. Not sure if the 400 GPH has a bigger propeller, but I would imagine it would. The outside of the pump is the same size, so it should be bigger.

Thanks for the info. I have a small powerhead in my shrimp tank, and I use various bits of filter or cloth over the intake with a rubber band to hold. I wanted to use a circulation pump, but like I posted, I thought the prop would be a death trap. It certainly looks more elegant than what I'm using now.

Hey what light do you have on your 55 it looks nice. I've been trying to figure out a light for mine.

That is the Finnex Ray 2 DD.

Is it better to get 2 strong pump and place it in the middle of the tank instead of at the end of the tank?

[DragnX]

Some more input? And also would a Hydor Koralia Evolution 550 be too strong for the plants and fishes?

Guess it depends on what you have for water movement via you current filtration. I run two cansters on my tank and a koralia evo 550 would be too much on my tank. If you are only runnng a single canister with low flow like an Eheim, it could work.

Edit: i notice you have a fluval. Which model? With your large plants, the additional circulation pump would be a good idea.

[DragnX]

Opps without to mention that. I using a marineland 220 canister. The flow is ok about half the tank.

I'd go with two Koralia 240s on opposing corners of the tank. I had a 425 on my 50g and the flow was too much for my liking (combined with my 2217 output). I added a 240 and another 2213 and things are just right.

So you are running two filters on your tank??

Yes, a 2217 stuffed with coarse pads and a hydor heater, and a 2213 stuffed with floss and purigen pushing through a co2 reactor. The 2213 adds very little flow in a tank this size. The 2217 and 240 do most of the water moving.

Any more input from people that have a 55 gal tank??
