hey i have a 29g biocube and i have the return which pumps out about 270gph and i also have a karolia 3 for flow across the tank. sometimes i feel like this is to much flow to be going across the tank because some times the smaller fish like my goby seem like they get blown across the tank. Everyone in here knows the biocubes pretty well so what do you guys think

depends on what kind of corals you planning to keep..for LPS an softies, i think that will be good..but for sps..you might need more flow..don't worry about your fishes..they be fine.

In my standard 29g aquarium I have a K2 and a dual bakpak skimmer that runs a Rio 800 and a Maxijet 1200. Works out to 37x tank volume. Take off the slow down the skimmer causes and I'm guessing it's still 25-30x tank turnover an hour. I have a yellow clown goby, 2 yasha gobies. The yasha's always stay with their shrimp by the burrow so I don't really know if it's to strong for them. The clown goby doesn't have an issue. My ph is aimed at the surface from a wall. The flow goes across the top of the tank toward the right and then loops around the bottom back to the K2. The skimmer kicks out water near the top and it hits the front glass (if it makes it past the K2 current...lol probably not). The goby chills on the rock at the middle level of the tank.

I have two Quiet One 3000 pumps (780 gph each = 1560gph total) ; one as a sump return and one as a closed loop on my BC29. Both are on their own SQWD for alternating flow. I'm sure I loose some flow with head pressure, but the flow is still pretty strong. When I put a new fish in the tank they get tossed around a bit at first; doesn't take them long to learn how to swim in the current and they swim around like nothing. The corals love the flow, just have to be sure not to point the output directly at some pieces as it could be too strong. My main problem is combating sand storms with this much flow.

I'd definately say what you are running is not too strong.

Looks like a choati leopard wrasse.

Yes, that is right; it's a Choati wrasse.

But your pic looks a lot better than the marine center's. It's a very nice photo and nice fish.

Is it difficult to keep?

Not too hard to keep; gotta have alot of pods and a deep sandbed for them to bury themselves in. We had him in our 375 gallon; wouldn't be suitable for a smaller tank. Hard fish to find though; I searched for months for one and unfortunately that also means they can be pricey. Definately one of the fish I miss the most from our old tank.

And Now Back to our Regularly Scheduled Programming...

Sorry chris for the Hi jack!

Back to Flow! I agree that the fishes will find their own happy medium. They'll go to a place with less flow if they need it.
