Maxspect Gyre 130 pulse mode

[rffanat1c]

I know the manual says that use pulse mode at your own risk due to stress on aquarium seams. I've got a standard 90 with my gyre as my only pump. Does anyone here really think running pulse mode at less than 50% really endangers the seams on my tank? The tank was brand new in August of 2014.

Also does anyone have any experience keeping LPS and softies with this pump? Which mode is best? My frogspawn didn't like the constant mode but seems to like the alternating gyre. I've read the pulse mode is closest to nature. Thanks.

I think you're fine. I have my 150 set to pulse at 50% placed vertically in my tank, with the two sides aiming different directions. Happy corals with no dead spots.

Are you running an A+B propeller or A+A or B+B? Which corner did you place it in and why vertically? Mine is horizontal on the right side near the water line right now.
