With the calcium reactor fix out of the way, I started cleaning the nasty old pumps I got used. I hate it when the used stuff is not cleaned. So I got 2 buckets of citric acid going, and scrubbing off old fish poops...it's nasty. And 1 big old smelly Regal Octopus 300-INT skimmer, I might clean it up and sell it, not sure yet.
While the pumps are disassembled and soaking, I'm going to start planning for my electronics board, and try to make it neat and pro looking. The overall space is ~ 30" high and 24" across. Here is what I got drawn out on Excel where I want to put most of the controllers. White part is where I will drill holes. I don't have a hand router, so it's mostly going to be drills and jigsaw.
Any tips, feedback or critiques welcomed as I've never built/done a electronics board before.
