LTC or OGC mode set up

It all depends on where you have the pumps located. If you have them in opposite sides of the tank facing each other, then there is no need to have each pump be able to move water in reverse as the pump on the other side will push water in the opposite way. If you only have one pump, then yes, having the same pump run in both forward in reverse will benefit the tank with different flow patterns.

Unfortunately there is no clear yes or no answer. The answer is pretty much "it depends" on where you have your pumps installed. Every tank is different so all depends on the individual's configuration.

If you have pumps on opposite sides of the tank, then I think it is a waste to have each pump do both forward and reverse when you can just slow down one end and ramp up the other to push water one way and then to the opposite to push water the other day. A full pump where both sides of the pump push water the same direction is going to be way stronger than two pumps running half force. Does that make sense?

I would use the LTC or create my own schedule. The OGC will run your pump in forward and reverse which is something you do not want when you are running two pumps opposite to each other. My recommendation is to put the two pumps in random mode... no sync or anti sync. Just put each on independent random mode and let them work. you will be amazed of the different flow patters that will come out of it.
