i am just trying to figure out what to really look at. i have got 2 tanks that need light. that would cost about $225 for each light. so i was wondering if a simple set of pc lights would be ok. one is for a 20g and the other is a 10g.
the 20g light has 65 w and the 20 idk yet.
my goal would have been to get these:
20g = curent usa sunpod
10g = nova pro extream
but my current budget doesnt alow me to get both lights and i would like to get some type of light on there soon.
any help would be great.
thank you
