I've been using Sunsun's CUP-613 on my 180 and it did great. Just make sure to maintain the unit in intervals and change the bulb every 6 months and clean the quartz tube as recommended.

I won't bother to read this thread, but good and cheap don't usually go hand in hand. Research good.

I have had great luck with Green Machine uv lights from petsmart. Sun-sun seems to also get great reviews on amazon.

If all your doing is fighting green water, i think either one should be ok. Long term mybe not, but for the price it might be worth a shot..
