Ok, long story short:
- my RO top up sit on a high shelf in the garage and was been filled directly via the RO/DI filter.
- My wife woke me at about 2am to ask if i remember to turn the filter off.
- This morning I began to re-arrange and dry half the garage and everything on the shelving.
So the timing seamed right to expand the frag/s system. Got a 4ft, gave it a good scrub and detail, some basic plumbing and vinyled the back and sides. Built a new stand with the help of my snazzy new saw (might be a trade of for a pair of occidentalis, which I'm not yet sure if I'm happy about or not???) and a coat of paint. Re-arrange the garage and put everything back.
