There is a couple of different ways to feed the fuge but I think the manifold is a great idea. Plus it will give you the option to feed other equipment as well.
You could also harvest some of your algae and increase fish feedings. I don't know what your stock list consists of, but it wouldn't hurt. Getting both parameters low or undetectable has a risk of causing a Dino bloom.
Hey all jokes aside. How is the ABC holding up? Have you done a ATI test or similar to see how all of your parameters are? I've been debating using the AF Components Pro
I've also read about these shortages, hopefully when my time comes to fill up my tank things will start to line out....IO should be available now though! '*HaHaHA*'
For me I would go with the apex, convince with on the phone monitoring, safeguards incase something bad happens you can program it to shut it down, be able to trend the results, etc
I'm not for certain but I think you're referring to a pm1, if you have that module and the apex it would be cheaper and more efficient than ordering a Milwaukee
