The sebaes are 10 and 20 months old since i bought them. THEY WERE DARK WHEN I BOUGHT THEM!!!! They bleached a little bit, each one after about a month and then got even darker. The larger of the two has a diameter of about 10 inches. It was originally about 3 inches in diameter, it is the older of the two. The condy. (I think that is what it is) is about 6 months old. Got it for a steal from a store going out of business. $3.00. Lighting was originally 4 20 watt NO fluorecent. About 8 months ago, I add 2 55 watt compact fluorecents. (PFO) 1 CF is a 50:50 and the other is a full spectrum 6500. I still have the NO fluorecent lights on as well. 2 actinic and two full spectrum 10K?? a total of 190 watts on a 29 gallon tank. CFs are on for 8 hrs and NO are on for 12 hours. NO=normal output.
Thanks for the compliments. I will try to get better pics in time. Any questions, let me know.
