Pretty bulletproof plumbing ya got there! It's almost like your are preparing for a bigger tank!
That would be correct, sir! I've tried to purchase equipment that will scale with an eventual upgrade. The skimmer probably is the one piece of gear that has to be purchased "right-size" for the individual tank. And I'll probably switch over to the SpectraPure media reactors for carbon, GFO, and biopellets. I really like the way SpectraPure plumbs them with the valves that allow flow to each cartridge to be controlled individually.
