Zero maintenance, no drip or water changes either by the way. Just top off the sump when it gets low. Plants, reasonable bio load and the 3 coryadora that I rarely ever see keep parameters pretty much flawless.
She blew a seam last Friday. Corner bracing on top broke loose, which let the silicone bead break a bit In 1 corner. Wondered why there was a puddle outside the sliding glass door to my fishroom that morning. Lol. Re-braced all 4 corners w pilot holes and 1-5/8" trim screws, re-siliconed that corner internally wet and gorilla taped the outside of the corner. Decided to make it open top after that, and it seems like it just needed attention and a revamping. I like it way better after catastrophic failure. Lmao
