I love the tank, great job so far and I hope everything continues for you. I just ordered a PAR meter as well because I also have 3 kessils over my tank and I think I have them set a bit high. Just for reference I ordered the new Apogee SQ-520 which provides accurate readings for LEDs(full spectrum). Its a unit that hooks to a laptop but its cheaper and has a few more features than the MQ-520 which has its own head unit. If you go to apogee's site they have some really informational videos on LED PAR meters and the reasoning behind the inaccuracies of the units that aren't full spectrum. Only problem is they are backordered until mid July but will be shipping out all backorders then. Good luck with everything and have enjoyed following along.
