help with settings for duel Gyre Fx350

[Leandre]

hi guys, just bought two of these and wondering how others have set theres.
Tank is 72x24x24
i have them mounted on the sides around 3" of the water line.
Currently have them on OCG setting at 60%/30% high/low

does that sound ok?
or would doing it on manual on alternating gyre be nicer?
any help would be appreciated.
thank you~

I also have 2 in the same size tank. Because of my setup & rock work, 1 pump sits vertically on the back pane at the left side of the tank at 70% constant. The other pump sits horizontally on the right pane near the top of the tank, also constant at 70%. My setup creates plenty of turbulence & sps polyps dance all over the place. The setup works for me because of my returns & rock work. I suggest setting up your pumps according to how your coral reacts

I did something similar to what you are doing. In the end I ended up doing long alternating pushes. 1-2 minutes pulse per side.

I also programmed them to do a sweep I saw somewhere for an hour a day. It moves the contact point of flow across the tank to kick up detritus.
Basically
% for about 10 minutes each.
20/80
20/80
30/70
40/60
50/50
60/40
70/30
80/20

Right now i dont have any corals, so im really working the corals around these pumps. The wife wanted a mixed reef leaning more to the softies so i have a shelf in the middle of the tank around 15" tall for sps, the rest of the rock is lower. i was thinking that setup you have might be too much flow? i dunno. i kinda like the standing wave, 80/20 one at a time, get some swaying?

so you set a time during the day when the pumps will have a strong flow to give things a clean? what flow mode would that be? and is that the 50/50 point in your list?

It was a while ago on my 180g so I'm running off memory for percentages.
The basic jist of it was both pumps on constant at different intensities. For example gyre on left at 20% and the other on right at 80% will result in the two flows intersecting and creating turbulence on the left side of the tank to kick up detritus. It runs for x minutes that way. Then the next set point kicks in at 30% left and 70% right so the flows are intersecting a little more to the right, hopefully pulling up detritus from that area. Left pump continues to increase by 10% while the right decreases by 10%. So 50/50 would be meeting dead center of tank. The goal was to create a long slow sweep across the length of the tank with the intersecting flow points.


All in all it appeared to work alright but was a total pain to program on the 350 controller.
My tank was sps dominant so I just cranked it all up and I believe ended up on very long alternating pulses and was happy with that result more with that for my main flow pattern.

i also forgot to mention. i also have 2x neptune wavs in there about half way down on the sides, left side is more to the front and the right side is more to the back. the idea was to have them keeping anything that detritus that falls down suspended.

right now i put it on LTC mode running at 60/20 but i was wondering how would i get a wave on with this? llike left pump on for 40 secs ( right pump off) then right on for 40 secs and left off, or is that not a good idea?
once again, thanks

While you won't get a wave, like a wavebox would make, I think you'd really like a long pulse pattern and is worth a shot for sure. I felt I got extremely natural and thick growth on my UNS tank's acropora. It was a 4' peninsula but bare bottom. I would do 1 minute alternating pushes on Constant @ 80% with my mp40s.
Same could be applied to the gyres and your tank. Find the max output the tank can handle for an extended push and due long 40sec-2 minute pushes while the opposing pump is at a constant 20%. This will give you a nice blow one way, stall momentarily and then blow the other way on all your polyps, torches ect. I like very high flow, but if you need to go lower for your coral needs maybe just extend the pulse duration at a lower % and see how it goes.

Have you considered buying the Hydros Wave Engine? They make an LE version that controls two pumps and you get custom programming and more control. I have the ETM full version and love it, especially that I have my MP40’s and gyres in sync with each other.

Thanks for the reply. I have not, to be honest I didn't even know about this lol. A cursory look sounds like the Ie6? Where you have more control over your pumps but the hydros having the ability to use other pumps too? The 2 fx350 and the wife let me get a 3rd kessil ap500, if I ask for more I might have to sleep on the couch.. In the car right now but I'll have a proper look a little later. Right now I'm using one of the pre existing settings, ecen at 40% it's blowing sand in the middle of the ta k everywhere. Need to find that balance of flow and no sand storm

If you're only going to have 2 pumps, then this may be overkill for some? But if you think you're going to add more flow later or you want more control, the the wave engine (full or LE) is the way to go. Also, if you need a controller or something to monitor your tank, the wave engine integrates into the Hydros control family. It will also power of units off a single power supply. My new nano build will be an all Hydros system.
