Hi Sana,
I've had the MH's on the 225 since 6/2005.
When I set up my 180 last year I used T5's. I love the colors, the lack of heat, no chiller and lowered electrical costs.
I can work on my 225 inwall from the back room with the lights on it OK. It's changing the bulbs that is the problem, as we can not get the fixture out from the back room.
We have to access it from the front. This involves precariously standing on the back of the love seat to remove the large pictures over the tank that hide the front access and then lifting the 45 lb. Maristar fixture down, then reversing the procedure to put it back up....UGH!...
Thanks!
Joyce
