Two Gyres- Bean Animal

[Terry4505]

If you turn off the gyres, I'm assuming you can get the system dialed in and silent. If that is the case, then here is what I think is happening based on my own experience with regular powerheads aimed upwards.

When the gyre pushes a lot of water, there is a sudden increase of water volume into the overflox box. You are not running the gyres at a constant speed, so every time they ramp up, the volume increases. Imagine that you have a ball/gate valve on your return pump line. If you quickly opened the valve then returned it to the original position, you would have the same gurgling from the non-siphon pipe. When the gyre pushes extra water into the overflow box, it has to go somewhere. The siphon pipe is at capacity, so it goes down the non-siphon pipe and causes increased gurgling.

I think you will have to either reposition the gyres, change their mode, or reduce their intensity.

That is basically the conclusion I've come to. I dialed back the return pump a bit, and turned down the Gyres. I am going to program that Gyres so that they are on higher during the day (when I'm and work) and lower, and thus quieter in the mornings and night.

Problem solved.

I was running the Gyres on the pre-programmed OTC setting, which had the Gyres alternating, and wasn't working. I took some time, learned how to program the 200 series controller, and have them on a program I created that has the tank silent when I am home in the mornings and evening/night, I don't care if it is loud during the day.
