ok, so it stayed like that for over an hour, I unplugged the controller and plugged it back in and now just the two red lights are on with the pump on constant. I've tried all possible combinations of unplugging and plugging back in.
It is very rare for a 6091 controller to fail, the most common culprit if it is indeed the controller is that water entered near the foodtimer button, usually from being pressed with wet hands. It is also possible for the pump to stop responding to a controller. Do you by chance have a 7091 or 7095 that you can check the pump with?
Yes, the manual shows how to open it, you can look for any salt creep or green corrosion to see if it was caused by water, you could also check for a broken wire, each cable has 3 wires that should be soldered to the board.
I just use a slotted screwdriver and pop it off by prying it up. A useful tip- turn the knob all the way counter clockwise or clockwise before doing so, the knob can go in two ways and it is much easier to reassemble properly if you turn it all the way to on side and make a mental note of the orientation.
you were dead on Roger. I opened it up on saw a bit of corrosion. Clean it right up with a q-tip and ro water. By the way, I didn't know about the asynchronious mode. It's amazing on my tank. I got waves right away. I'll have to post a video soon. Great stuff!
I tried it out more and found two sweet spots. One fast pulse gives me a 2.5"+ double wave, and a slightly slower pulse gives me 2.5" of a normal single wave (ala rectangle tank). This thing is amazing.
Any idea what the ideal depth would be? Since it is asynchronous mode it isn't using much more than 3" or so of displacement.
The wave height is only about 1/2" lower when the pumps are at 6 inches off the bottom as opposed to 14 inches off the bottom. This is with the pumps running at minimum speed. Which height do you think would benefit the future tank inhabitants most?
I had to do some major modification to the box and both pumps to get them to fit. As it is it's a very tight squeeze. I had to dremel out a ring for the housing to fit into the box. What you see a ring of 1/8" thick ring that used to be 1/4" acrylic. Without this additional 1/4" (combined) of space the pumps would not fit in the box. I also use flat o-rings between the housing and the box to create a better seal and reduce noise.
