I have a rio 125 with the T8 Juwel I-Bar and I want to achieve the 2WPG+. I want the lighting to be concealed under the flaps, I've seen some people buy the the ballasts with a control attached to it, so effectively I would probably go for a twin ballast but I've come across a few brands and I'm stuck also with size, I think I have to get the 60cm-24W ones, am I correct? Also I not sure If they do T8 ones, is it ok to mix T8 And T5? one last question is I've read people balance the extra bulbs on the center brace, now it sounds a little dangerous, I could probably stick on some blocks on the ends of the aquarium to create a platform for the end of the tubes... is this the best way to go about this or does anyone one have a better suggestion or mayB a link to someone that dose? please help, thanks!
