Hi all, I've been enjoying the forum for a few days and I'd like to ask your opinion / possible experience on the mod I am thinking about. I have a 60 x 30 x 35 planted tank (just started) and I am not really satisfied with my T8 OTL which delivers just 30W in total. In order to make the most out of the light produced I have thought of a few options: -Surface skimmer: Eheim SK seems a good choice and good value, if not a little bulky. Â£30 -The perspex sheet on the OTL I suspect dims the light somewhat, so removing the innards and replacing the fittings with aquaseal starter would allow me to to run without this perspex sheet. Â£30 -Go for T5 compact, could easily fit 72W in there I reckon. Â£50 I use easycarbo and ferts as needed, no CO2 injection Does anyone have an opinion the amount of light I can potentially get, and ease of installing new tubes / clips in OTL?
