ok guys i got a 75 instead of the 125. and i was using the 4x t5 from my 55 and it doesnt quite cut it. so i ordered a new light setup its a 6x t5 it came yesterday with 6 bulbs included. has anyone heard of Hopar HP T5s? and are they any good? Or should I go out and buy 6 new bulbs? also the tank being wider should i go 3x whites 3x blue or is 2 blues just fine? On the 4x fixture i ran 2 blues and 2 whites and that worked great for that system. aside from the T5s i have a diy 20 blue led lightbar that i made for a total cost of about 15 bucks and thats my night time light. Also I would like to hear about your guys' photoperiods, how long are they? How long should I make mine to keep coral healthy and keep the electric bill as low as proper husbandry will allow?
