My WAV pump stopped working 2 days ago. I don't know if it's the 1Link or the actual pumps. I've tried everything, restarting neptune apex, updating, unplugging and replugging pumps in different positions, etc. I do notice the led light on the power supply blinks and is not constant. Weird is that it stays constant if I unplugg power supply from the 1Link. I called apex and it's a recording for if you want to place an order leave a message, nothing else. I left a message anyways and nobody called me back. Only way is to email and they will get back to you. I didn't have time for that. I just went ahead and ordered new unit and I will find out what the issue is soon enough when the unit gets here. I have too much invested to have any down time on my tank.
I agree, contacting them is not easy. They can work on having a live tech support dept as big as they are?
But when it was working, it worked fine and super quiet. they do push massive water, sometimes too strong and focused. You really need to becareful with these in a smaller tank, less than 90g I would say.
So i finally figured out that one of the WAV pumps is bad. I realized that if you have one bad WAV pump the other(s) WAV pump will sieze to work as well. You have to unplug the bad pump for the remaining good pump to work which I thought is lame. While messing with the bad pump pulling it out and plugging it in a few times, from the 1link, to see if it would start it fried one of my EB8 and my PM2 Module. Weird because it didn't fry the other EB8, 1LINK, remaining wav pump, or main controller module.
This is a huge flaw with neptune equipment how 1 device can potentially fry entire system! I couldve lost entire neptune apex and could have had to replace the whole thing. I wouldn't be able to do that so thank god it didnt.
This is very similar to what happened to o2manyfish.
This is where ecotech mp40s would benefit by being an entirely independent unit away from neptune. Having neptune apex is cool and has it's advantages, but imo you shouldn't hook everything to it. If you have ecotech lights and ecosmart already go with mp40s. I'm forced to replace my one wav pump because its currently the cheapest and most logical route.
