I have a 8 year old JBJ 28 nano cube seen it’s ups and downs once was full of SPS at about the 2 year mark to being inundated with bryopsis at 4year mark and a lost battle on top of that the LED hood died almost 450 to fix (replace) ran with a cheep led light to keep the clowns and anemone alive. Son rescued tank and JBJ came out with new WiFi led hood at 6 year mark now it’s a Zoe and LSP growing machine looks great. The JBJ refired the spark in me and I started a mixed reef Aquamaxx 22 gallon book shelve tank last Dec 5th at almost the one year is looking pretty good with only a bit of GHA on the lower rocks. Hopefully last hurtle as I have a very fat lawnmower blenny and well feed CuC.
