gogol said:Thanks a lot for the info jerzsky. I contacted the guy again, and he said that if he does provide the 150 , it will be with ballasts for 150 and I would not be able to put 250 without replacing the ballasts.
So for the 20g I would go ahead with just the t5s.
Yes I do use pc lighting right now and would be looking out for petscreens for the acclimatisation. Any ideas where to get them?
Again thanks so much for the advice, I will need to find out how high I can suspend the lights in my current setup.
