Agree. I have 2 and they have been running from 1 1/2 year but decided to try the Gyre with the vision to have more visibility on the tank.
At this point I really like it but to me it seems that the XF-250 doesn't get to the opposite side of the tank in OGC mode so I am evaluating if I really need 2 and have the Jebao as backup.

Can somebody check on the Advanced Controller if when you are at LTC or OGC mode the pumps ramp up or down to the percent you selected?
As you can see in the pic I have set it to 100% and it only goes upto 30%. This confirmation will lead me to establish if it is a software bug or I have a bad controller.
Thanks in advance...

Couldn't find any literature on the OGC and LTC modes, but it appears to run on its specific program based on day and maybe time. Notice the D1 symbol on the first day and D2 on the second day, etc. As the days pass, it will ramp up to the max setting. This was problematic for me when turning off the pump because it would start all over again. Im now using random mode and have been happy with the flow pattern.

Hummmmm that makes sense. There is nothing in the manual regarding a type of day cycle neither in the graph.
Can you share the random mode settings you are using and what size tank you have?

Actually, the D1 thing is a time offset. According to a mod on the official forums for the US distributor of these pumps, the different day settings simply offset the high and low tides by 48 minutes, as it is in the oceans. The peak tides in the ocean are off by this much because the moon's rotation puts it ahead slightly each day, increasing the times of peak low and high tides slightly.
I currently run two 230s in my 40B, and I'll say, I've never seen flow like this from just 2 PHs, ever. I've replaced the 4 Koralia PHs that I owned for the past year. Even with LTC running the pumps at 20-40 percent most of the time, I get a little too much flow for a mixed tank. I'm also curious as to why it seems to never reach the maximum values that I set, but seeing that LTC will emulate periods of calm ocean and rough ocean, I think that it only reaches its maximum during periods of high ocean current.
Perhaps that's why periods of low current (high tide, when the waves are a decent distance above the corals) are at night, and the opposite (when tides are low and the waves are crashing into the corals) happens during the day. At least, that's what I notice from my pumps.
I do like how the pumps alternate with being the "dominant" pump though. It seems like if you run two pumps, one pump will run stronger than the other at a certain period of the day, and it switches, which helps to keep the general flow of the gyre balanced between running predominantly lefthand and righthand. This has been the best mode for me, my corals aren't being blown in just one direction at any given time, and I notice that the coral is being "sloshed around", yet I can clearly see that there is mass water movement from both pumps, I think I'm getting a healthy dose of flow from my 2 Gyres.

Thanks for the feedback and yes I agree with you that haves to be with the time of the day but the manual just doesn't say nothing.
I also like mines and has nothing to compare with the Jebao RW-15 I had installed. To be honest I played a little with the LTC but really stucked with the OGC which I love and I am running it at only 30% up and reverse. Thinking to ramp it up to 40% shortly. Did you try the OGC lets says for several days?
Now my debate is if I get another for the other side and if I should stick with another XF-250 or go lower.

I think if you went with another 250, you could run both of them at even less power. I think even at the lowest settings though, two 250s would give insane amounts of flow for a 70.

Dude tried the OGC mode , it worked fine, I think the LTC mode is better for bigger tanks , though two PHs would really rock. Right now im running the ramdom mode 80% max 30% min. Still playing with it. Do you or anyone else know about the D2 setting and what's it's for ?. Feeling not to smart with this OH lol

Thanks Buddy. I will give it a try and see which one a finally decide but at the moment the soft corals and fish are looking great.
I wrote Coralvue to see what the D1 and D2 really means but haven't get an answer from them yet.
