We just took our 120 down over the weekend, it was about 3 years old. It was just to deep to work on without armpit bruises and lots of frustration! Just wasn't fun anymore. So we decided to keep the same stand/equipment/canopy and just get a tank 1/2 the height. So now it's a 60 gallon that is 24x48 footprint but only 12 inches tall now! So far it is much easier to deal with. It has a 3 piece sump, 2x fuges and a filter/return sump. 4x54watt t5 and 2x kessil a150. Mostly high end zoas, a few sps pieces, a few open brains, chalices, anemones etc. MP40, MP10 and a Tunze nano wave box.
