Aha! That looks sweet! Do you have one in operation yourself? It definitely looks like it could be the missing link for the RDWC systems. Great work man.
You think koi people are crazy? You don't know reefers (aka reefkeepers). If I'd known you were spending all this time researching I could have saved you quite a bit of time, this is stuff I've written about quite a bit, consulted, etc.
One caveat with dollar store scrubbies is that some of them may be impregnated with anti-microbial agents, which would sort of undo all that hard work you just put into building a biological unit.
Back when I started using them, they didn't always. But now it's so popular to make Suzy Housekeeper feel as though she's keeping her family safe and sound by using anti-microbial products, that it's become much more popular to make such claims very prominent. I mean, have you ever tried to find a non-anti-microbial hand soap lately? I hate that, seriously, people have no idea what they're doing when they use this stuff.I actually stumbled across a few of your posts in my travels.
I too used to keep (2) reefs, but broke them down/sold everything when I moved to CO. Swore then and there I would never set one up again until I own a house I will NEVER move from...
'Researching' is how I like to spend my time.
Would they say on the package if they are impregnated?
SS scrubbies are definitely not, correct?
