Those vases will work as a reef, but with major differences that affect salinity. thats experimental, mines for sure, you have to choose.
drilling these is -hard- without ruining them, my lids are plastic those are glass, see some work coming
Gentleman Mark, Warlion on this site, did the drilling of the vase on my article and he made those pictures I have no glass drilling skills so a plastic lid is where i route incoming wires. Warlions drill into hobby glass was amazing, I used the grouping he shows on his Flickr page because as he and I chatted about vases he mentioned having that ability to drill, I was amazed at the carefulness required
your challenges in using nonstandard vases for reefs are salinity and scaping
salnity control above all, the lid interface I use has been R and D'd
experimenting with new approaches is great, but not guaranteed. there's always room to improve, so anyone who finds a better lid interface will get the benefit of an airstone degassing their tank like we do in aquaculture, and even more reduced salinity flux.
regardless of the pico shape you use, mark your .023 water change water line level with a magic marker dot on the outside of your tank
as the tank evaporates, and the salinity climbs, that dot will be above your water line. add distilled to bring back, depending on size of tank you'll see the max distance before topoff.
