ok i need to bump this because i want to do a couple sps near the top of tank in a 4 bulb fixture what bulbs should i go with as in what rating i always used 50/50 power compacts in my nano so lighting spectrum is new to me.
I ran ATI bulbs with two aquablue specials and two blue plus with great success. Ran six and eight hours respectively. Had to replace every 11 to 12 months.
