Ok so i am finally after waiting too long getting some reefbreeders. I have a 35 g 24×24×15 i believe thats right dsa tank. My question is the phton 16 is only $10 dollars cheaper tham the 24, could i get away with the 24 since it is bigger for whemever i decide to upgrade. The part im confused on is the 16 actually has more leds and watts than the 24 juzt wonder if anyone has any experience with this
