Debating gyre pumps for my new tank

gotmesalty77 · Jul 7, 2019

I've recently inherited an 80 gallon rimless and it was severely underpowered in terms of in display water movement it already had a icecap gyre 1K and some other crappy power heads. Should I get another 1k or should I get a 3k and sell the 1k? Any thoughts or opinions welcomed.

never used a 1k but my 3K pushed a lot of water across my 48” 70. I had a moderate size powerhead opposite it to create turbulence. I think the highest I could ever go was 70%.

I’d dump the icecap. They get too loud as they age. If it were me I’d get two maxspect 330’s or 350’s and go won’t have to worry about flow anymore. I have 2 350’s on my 210g nearly silent after a few day break in period

You can dial down an oversized pump, but you can't get more out an undersized one.

I just got 2 XF330s for my 48x24x24 and dialed them in today. The controller took a while to learn and I had to resort to YouTube to figure it out. That's said, in antisync mode, they do exactly what I want them to. I'm running pulse mode with the longest ramp up and down times from 20% to 100% over the 8 hour maximum period. Moves a lot of water. My only concern is a lack of battery backup. As someone mentioned above, IceCap may have issues which I can't speak for. But my only concern at this point is having some form of backup. I can't imagine needing much more beyond that from the pumps or controller.

You can use the IceCap battery backup for your Gyre pumps: https://www.coralvue.com/icecap-battery-backup

Just to be clear, this is compatible with the 300-series of the gyres? The wiring or installation guidelines aren't easily apparent on the site. What kind of runtime am I looking at for two XF330s?
