The Waterbox Marine X 90.3 glass sump contains a 2.8 gallon ATO reservoir. It seems like this space could be better used as a refugium (or simply space for another reactor of some sort). Has anyone repurposed this space? Options seem to be:
- Pump water from the skimmer chamber over the wall, then let it overflow into the pump chamber? (seems dicey)
- Drill the glass between skimmer chamber and ATO? (I don't think it's tempered glass, but seems scary to drill an internal wall)
- Remove the piece of glass between skimmer chamber? (razor blade the silicone)
