I came down to water lapping at the brace bars this morning.
The main drain has been blocked for ages, don't ask.
Something was blocking the back up!
I fiddled with the valve to see if it would un block, bulkhead went!
Unplugged the M1 and the Eheim for the cube and took the spraybar off in the display and angled the nozzle in the cube up.
There may have been various expletives dropped!
The two drains for the display are over the return section of the sump, less of a panic than when the one on the cube went and fried my electrics.
Trip to lfs.
Upgrade bulkhead and fittings bought, snag one, reaching the nut in the weir.
Picture me on a folding work bench stretching 26 inches across the tank and 18 inches down in the weir!
Did I mention expletives?!
I had to adjust the angle of the bulkhead below to nip the nut down so I used a zip tie to the secondary drain, ... and then I have the secondary drain in my hands!
... lots ...
Back to the lfs.
The only thing they had left that would fit was a pre made piece from a tank, no problem.
Except it had to be tighten from inside the weir again.
I have tried three times to nip this up by hand and failed, no I couldn't find a wrench.
So we are semi running, the M1 is not running in the display and the spraybar is off, the Eheim (3000 I think) is throttled back to give a slow turnover in the cube and fuge.
I have the RW 15 on a pulse mode for the display and aimed up a bit.
I have a constant drip into the sump which I can live with, I will find or buy a wrench tomorrow.
The water does slowly permeate between the two side so I am just trying to cut the flow to that bulkhead
The twins have 6 bulkheads by the way, all replacements being ordered next week and will nudge me up to one inch drains.
