Enough Flow?

MitchSutherland · 12/13/2013, 12:44 AM

I have a 125 gallon tank. Its 72 inches standard size. I love tangs, but i also want to do my part and provide as much flow as possible. I am looking at trying a gold rim achilles hyrbird. (Anyone have one? Any tips?) My flow right now is peninsula style. I have 2 korolia 750gph. 1 950gph and my return pump which is 1200gph but after head pressure being lost a couple feet i am guessing 750 as well. Is this enough? Or do i need one or two more? I am about 3000gph all coming from one side.

I personally would do more, I have a 225 and have 2 6105 tunze's which are 3400 gph each and an mp40 on the back wall which is 3200 gph and an mp10 in the rock work in the corner which is 1575 gph and my return pump also which I'm getting ready to upgrade to a reeflo snapper dart hybrid which will be set at 3600 gph not including head loss and I'm probably still going to want more. You should always want quite a bit of flow to help with oxygen, decrease the chance of dead spots also so you don't have to worry about detritus buildup or food rotting in a corner

While 20x tank volume in flow is "sufficient", 40x is much better, so around 5000gph flow would be optimal IMO.

I wouldn't consider that enough flow. You are at the absolute minimum tank size for an achilles/goldrim hybrid and swimming room and oxygenation are very important for these fish. The swimming room is already at a minimum so I would lean towards increasing the flow significantly. I would shoot for 50x at least before attempting it.

The way I think of it is if you're unsure whether there's enough flow, then err on the side of increasing it. Unsolicited suggestion: take out the Koralias and put in one jebao wp60 and one wp40.

Thanks for the help! More flow it is!! Jerpa have you dealt with the hybrids before? Or know anymore information?

Not yet. I'm planning an upgrade and would like to keep one. I researched the Achilles and Goldrim separately because there wasn't much info on long term success with hybrids. From my research they are both incessant swimmers. Although the Achilles has the reputation for being difficult the goldrim still seems quite sensitive to water quality issues. It can be difficult to get either to eat but the Achilles moreso. Most of the long term successes were in 6ft+ SPS dominant tanks with flow on the order of 50-100x the DT volume.
