60 gallon sps cube and FLOW (1 Viewer)

[NarnyTheGreat]

I am trying to figure out what to do with flow in my tank. Currently I have 2- K4's (1200 gph each) alternating and a sicce 2.0 return pump which is 568 GPH BEFORE the 4 foot height of the return to the tank. I keep reading that with sps you need to have 20x or even more than that of turn over. So I am a bit confused. Do I have enough flow? Do I have to much flow? I dont know FLOW! I plan to upgrade to 2 jabeo wp10's in a few weeks. Not sure if thats enough.

Help!

Turnover and flow are different. Turnover depends on your return pump w/ head loss calculated. Flow is a little more complicated. You don't want any dead spots and you don't want any corals receiving direct flow 24/7.

Long story short, the same powerhead can have too much or too little flow depending on placement.

Oh, so my sicce pump is to small with a turn over of roughly 6 times per hour. So I need to replace my pump to increase the turn over?

That's the dilemma. Some prefer slow turnover so skimmers can have more time to work.

You'll get a lot of different answers on this. I prefer higher turnover for sps.

Well, by any standard my pump is undersized since the standard is 10 times per hour. Now I just have to decide a happy medium between my sps and my marine betta. I at least need to get it up to 15x per hour I would think.

Any recommendations for which pump I should use for a replacement?

 

[gm357]

Mag 9 if you're sump is big enough. Mags are reliable and excellent on head loss.

2 wp10's would be great for that tank . And if you need you add the k4's

I went to go check on the website and can't use the MP 10's because my glass is to thick. It would have to be one MP40 or 2 jebao wp10/25's


Sorry I miss read what you said. Yes 2 jebao wp10 s world work well.

As mentioned, you will get different answers on return pump size. I am of the "slower is better" camp on return pumps. I use an Eheim 1262 (900gph) on a 150g tank, and 20% of its flow is diverted to a refugium.

In-tank flow is really what you should focus on. I'd keep your current return pump and bump the powerheads up to 2xwp25s. It wouldn't be too much flow, and using wp10s might risk having too little. I've used Vortechs, Jebaos, closed loops, different return pump configurations, and I think wp25s would be good for your application. Just my 2 cents
