My tank is 36x24x20 tall with 2 mp40s at each side I have it programmed to run at different modes throughout the day at 100% but can’t seem to get the flow right. Too many dead spots. It’s mostly sps with lps on the sandbed. Would I be better off with 2 gyres vs the mo40s for my size tank. I really don’t like the wires inside the tank though. Any suggestions?
Thinking of selling mp40s and getting gyres your thoughts

I just put a Maxspect XF350 on my 36x36x20. At 30% it was still too much flow. Blowing sand everywhere in any mode. I switched over to MP40s and the RCA RFG nozzles. Plenty of flow without the sandstorm.

That the 75g ext? I have one and just put two xf330s in it. I'm barebottom and my tank just finished cycling so I only have 2 clowns in it. I like it so far but without corals in its hard to tell.

yes it’s the 75ext. What plans do you have for yours? I’m assuming sps being bare bottom. What about lighting?

The xf-330 is plenty strong enough for the 75g ext. I cant have them both set above 50% at once or water splashes out of the aquarium, which is fine because i'm running one anti sync but something to consider.
It's going to be an acro tank yeah, I have an 8 bulb ATI t5 for it. What about you?

Nice dude. Cant get better than that right there.
I recently replaced a Korolia with the MP 40, and couldn’t be happier. I did fix the broken one, and added it to the system as well. I have plenty of flow. 2250 g/hr x 2 + the MP 40. Minimum sand movement, my GBMC moves more. Little to no dead spots. Important : Don’t give up until you get it right. Mine are pointed up and across the tank. I always blow more water to the back wall and back corners , bringing dead stuff to the front. Works great.

Gyres move a lot of water. Price point the XF250's are ideal since they have high flow and you can connect two of them to a single controller and 1 power brick. There are a lot of things to consider though all things said and done. The biggest one is that the younger the tank is as it relates to maturity and coral growth you will get frustrated rather quickly with the flow and patterns. Like I said - they move a lot of water so the trick is to balance it without causing harm to some corals (LPS comes to mind) and substrate if you have it. Meaning - you have to have rock work and coral(s) and growth to break up the flow for fish to hide, etc.
You can alternate left, right by time. You can lower power reduce flow. You can swap paddles and alternate forward and reverse. You can mount horizontal. You can mount vertical. At the end of the day I was just the opposite of you. I was going to sell both of my XF250s for mp's since my 210 gallon is still maturing and the gryes have been a bit of a pain.
@pelphrey has a really good video that talks about the controller and flow. It helped a lot. Also there is the BRS video. I think Pelphrey's post lists both anyway. Well worth it if you are considering them. I have since taken one of mine off line for a bit until some of the coral grows to break up the flow.

I have roughly the same size tank and my Gyre XF230's were too much flow on anything above 40%. I loved them but ended up going with a pair of MP10wQD's. I do miss the wave action I got with the Gyre's but for now the Gyre's are too much. I'll definitely give them another shot when I get a bigger tank.
I have both and there both good pumps, Unless your unhappy with the mp40’s And the flow, I don’t think it’s worth swapping them out until one of them breaks and then see what’s available..

Have you tried both pumps on one side of the DT?

Nobody mentioned it... I got rid of my Gyre because it was a pain to clean. Lots of thin plastic, everything's got to line up just right...
The Mover's I'm using now, pull 'em out of the tank, put 'em in a bit of vinegar and run 'em for an hour. Brush with a toothbrush, and hang 'em back in the tank. Fast and simple maintenance. The MP series, which I don't own because of the sound they make, would be just as easy to clean.
