MP40's to Gyres??

[minus9]

So who has made the switch from mp40's to the new gyres (350's)? I currently have 4 mp40's on my tank and I'm thinking about switching two of them for gyres. My tank is 36x36x16. I have two 3/4" returns with VCA random flow generators (which I love) and two mp40's on the back wall and two on each side (one on each side). It's a sps dominant tank, so flow is paramount. The flow going to the front of the tank is great, but the sides aren't as wide as I want them to be, so I was thinking about using two 350's on the sides to widen the flow.
Any thoughts, experience or advice would be appreciated.

Gyres work great. But they are a real pain to clean; so I almost never clean them. For the money, they are hard to beat if you have time to clean them. I'd rather have more mp40s but the $700 for a pair is hard to swallow.
Currently, I have 2 mp40s on the back wall and a gyre 250 on the end of a 60-inch tank.

I hear the new 300 series are easier to clean and maintain. Maintenance isn't a deal breaker for me. I could move the two on the back wall to the sides, but that will block even more of my view. That's why I was thinking gyre up high and out of the way?

They're a little bit harder to clean; but they're not THAT much harder to clean. Take them apart, bleach, scrub, rinse, soak in strong acid, rinse, lube o-rings, return. I've had one for 5+ years and was making a TON of noise Saturday night (the other 3 are 6 months old and were fine), so I took all four 250 gyres and 2 Jebaos out and soaked, cleaned returned in less than an hour. As long as you pay attention to the cage and impeller direction, it's not that big a deal. The problem is when the you throw a bunch of gyre parts together and have to figure out what side goes where... I wish gyre would label "L" and "R" etc... that would make it a LOT easier to reassemble. But once you figure out how everything goes together, it's no more work than any other pump.

How well do the 330's hold to 1/2" glass?

 

[reacclimating 2 the hobby]

I love my gyres and really don't see the pain that everyone speaks about with cleaning. Once a month when I'm scraping the glass down I soak them in vinegar and RODI for 20-30min. Then once everything three months take them apart, put on the extra parts that come with and clean the others for next swap. Can't beat the flow for the price.

I made the switch on one side of the tank so far from the MP40 to the Gyre 350. I love the flow and will be switching the other side as well. Not sure if I will keep the MP40s for the back wall or not but the gyre pushes so much water I may not need them.

What size tank do you have?
I’m setting up a 300dd and thinking of doing 350’s on the ends and two mp40’s on the back wall. Already have new mp40’s.

I have a 187. 60x30x24
I have them turned down, nothing over 50%

Thanks for the input. Your move is along the lines I was thinking with the 350’s.

Hope this helps the OP.
