Is 2x turnover from return pump too little?

[Leopard Man]

As per above guys. My current return pump broke which used to give me 3-5x turn over. I'm thinking of buying a new one that will give me 2x turnover. Is that too little?

I have a Tunze 6100 though on a single controller for my 58G display tank and my sump is around 17G.

Thanks in advance.

In my opinion, it is not nearly enough flow for a return pump, but it will depend on what type of sump you are running.

I always shoot for at least 5x an hour tank volume turn over.

My sump just had two chambers, one for my Deltec skimmer, and the other for my return.

I think it is fine. Some people run 1x.

Wow, really? That's good news. Thanks sjm817.

I have been at around 2x for about 4 years now on my 120g.

I was at about 8x. My skimming wasn't half as good as it is now.

I would try and match it as closely as possible to the rate of your skimmer pump. From what I understand, having them the same is ideal, that way all the water gets skimmed.

I have mine dialed way back on my 180

Quieter and seems to skim better

The only issue that I could see is if you were/are running a HOB overflow.

But, if your tank is Reef Ready, then you will be fine.

Good point Todd. This is why we keep you around. Get well!

Thanks. It is scary that I am "smarter" when on morphine.

I don't agree with the low turnover rates recommended to you. In my opinion I would try for a much higher rate. In the range of 10X would be better for all inhabitants.

You will see the difference quickly should you go with rates like that.

That would be a fine (( if not higher )) turnover rate for inside the tank, but not through the sump.

Thanks, I did mention in my first post, that I did have a Tunze 6100 for my display which is 58G. Given that I use the Tunze 6100 on maximum, it will give me at least 50x turnover.

Thanks.

Yeah, this is one of those aquarium topics that could be debated for years. For me, I would have to agree with Don, and prefer a high flow rate. But as gh0st mentioned, it really depends on the sort of sump / filtration system you have setup. If you are running over some sort of bio-media (i.e. bio-balls), then you will want to drip water over them at a slow rate. If you are using a filter sock, and skimmer as your only means of filtration, then I would recommend a higher flow rate.

People have had success with all ranges of flow rates, but I would say the one thing that most people would agree on, is that the flow rate through your sump, shouldn't be less then the water being fed to your skimmer.

2x is just fine!

For filteration, I'm running a Deltec AP600 skimmer. I'm also running GFO on a reactor, and carbon. The deltec is gravity fed by a 1" drain which at maximum gives about 600gph. It is equipped with an Aquabee 2000l/h pump.

Why should the flow rate through the sump shouldn't be less than the water being to the skimmer?
