Cheeky. This guy/gal has a slightly deformed head, but functions normally for the most part.
Cheeky's mate. No name yet. Seems to have developed a taste for RCS and not much else.
What I spent the better part of the afternoon working on:
For some reason, I thought it was a good idea to add another double tap valve to this line, between the spray bar and the filter outlet.
filter outlet -> double tap -> reactor -> double tap -> spray bar
Maybe it's getting late but I had a good reason for it. But as I was putting it in, I was wondering why I was doing it.
But it's working nicely so far. I'll have to check on it tomorrow morning.
This also gave me a chance to clean out the filter hoses for the Eheim, as I needed as much flow as possible for the reactor to work. It was pretty gross.
Next week...cleaning the Fluval's hoses and putting the other pre-filter onto that.
