Same size tank here ( link in sig) and I have four A160s plus added some T5s, cost off the T5s was less than a Kessil. Tank still in its early stages and yet have to get the balance right as I lack the experience of George OFC. One minor thing about the A360 is you can only lower the intensity to 50% but the A160 can be lowered to 5%. which for me was a big bonus as I have setup mine up with a PLC (Programmable Logic Controler) which controls well basically everything, so I have a Moonlight passover period in the evening where one kessil is on at a time for period off time at 5%. Only just fitted the PLC last week, but the Moonlight period is so sexy I love it.
PLC wasnt cheap either but it controls everything even the water temp - well will do when termistor arrives, can even turn stuff on and off via phone
