did you just put an add on, to an old power head? You def have enough light i would just make sure ur flow is at least 40x. if you want you can try a piece of this easy birdsnest i have LMK
o man, i hope u didnt just buy that bc u would have been better off with a k1 or k2. Make sure you clean that at least once every 2 weeks as it will stop sweeping
yea never mind i forgot urs is a 15 u could get away with a k1 or nanok, IMO much much better then the powersweep. They creat a lot of random flow with out haveing to worry about
A. it getting clogged and having to clean it
B. Its not a blast of water so to speak but a more wave like stream so its not so direct
