Okay the tank is I wouldn't go as far as saying crystal clear but there's still a tinge of green in every color temperature so I'm still not disappointed that I spent the $34 on the UV sterilizer it's 9 volts and I know replacing the bulb cost $29 in the whole unit cost 34 but I put some thought into retrofitted in into the 4 by 2 foot print that I have to work with and granted I'll be on the step I should be able to do it I have to put some thought into it and I'll drive and I'll show you the plans that I carefully drawn so you know feel free to do it if you have a 29 gallon Coral leaf Coralife scuse me tank as well the budgets going to increase by about three or four dollars so if you've been keeping track that'll be about $3 3 + $34 A&D Juvia sterilizers have been known to live anywhere from 6 weeks to 6 months I think it's funny that the replacement bulb is $29 or they holding unit is 34 so whatever
