I'm happy to hear that you were able to figure something out with the gyres. I'm hoping that because mine are supposedly simpler that setting them up will be easier. I'm not pointing them straight at each other like you are so maybe that will make a difference. I've got the 4k set to stream across the top of the tank and the 2k attached to the back wall with one side pointed in each direction so hopefully there will be no dead spots behind the rock scape. If I pulse I think it's going to be longer pulses instead of short ones but we'll see. I decided not to have so much locline on my return so it will mostly just jet straight out from the bulkhead. Every time I try multiple pieces of locline it just ends up with algae and other gunk growing all over it even if there isn't algae elsewhere in the tank. I'm not really a fan but what else are ya gonna use?I take back some of my comments on the Maxspect app. You actually can set durations and such through the app at a more granular level. I don't find the app very intuitive and their 'manuals', a couple of simplistic videos and a QR code in the 'User Manual', doesn't really get you there. Right now I'm running 10%-30%, 1 sec pulse anti-sync on the two pumps. The pumps can run sync, anti-sync or time-delayed. Every time I try to test it though I need a half dozen tries to get the right sequence of thumb presses to get to the sync settings, etc. I'm sure I will get there but they should could use a little polish on the app and maybe some instructions.
