After Phil's latest post demonstrated his leap in progress, I hauled myself out of sickbed and got the following done...
- Emptied the tank - no leaks!
- Did a water change on the 30G temporary tank...was looking a bit yellow.
- Drew/measured the centre points for drilling.
- Drew/measured the overflow glass.
- Pulled the sump out and did some drawring.
- Eyed the spare 30G tank as sacrificial glass.
Sump overflow addendum
- 3/8 x 120mm
- 3/8 x 130mm
- 11.5 x 17"
- 15 x 17"
With what I have planned, the sump will offer ~13.5 gallons of overflow capacity. The weir capacity (at 40% more flow than I'm capable of) is something like 3 gallons. Overflow would hold, worst-case (completely full and emergency draining) another 3 gallons. Piping say a gallon. That means I'm still only at 50% capacity of the sump's possible overflow.
Measuring the drill points
I left a 2" gap between the three holes, and there's 70mm left over on either side. Holes will be 2" from the top of the glass to keep to the minimum safe distance while not taking up more room than necessary inside the display tank.
Bulkhead trimming calcs
Yep, will be trimming 15mm off the ends of the bulkheads in an effort to keep the plumbing a bit less awkward.
Overflow into the sump
No full sump shot, for some reason...but it'd be unintelligible anyways. The scrawled notes help my brain make sense of the measurements. Sometimes Sketchup can only get you so far.
Next steps, take my glass BOM and call the glass shop. If the 3/8" glass is super expensive, I'm sacrificing the old sumpy to save on glass costs. Good thing I have some capability of glass cutting in-house!
I also need to get around to visiting the pool shop for the Spa-Flex. Srsly.
Oh...and get my neighbour to help dismount the display for drilling. Drilling holes vertically is really the only way. Kinda sad I can't use the drill press on this tank.
edit: Pretty sure that's $25 worth of pot scrubbies. Estimate that I'll need an additional $40 to fill that area. :S
