If it's not one thing it is another. The ballasts are going out on my light, light is 10-12 years old, 1 fan needs replaced etc. Running a current nova extreme T5 54x8 lamp in a 55 gallon reef. Having a problem finding the replacement ballasts which will add up to about the same amount as getting a new light, but this same light is backordered for more than a month. Daylights are still working but I have no actinics. I love zoos, they are my favorite. If I bought a 6x54 system that would give me 324 total watts or almost 5.9 watts/gallon is this adequate for most all zoo's. Maybe I have had too much light for my zoos and that has resulted in some of my meltaways. Sure appreciate some info asap :squigglemouth:
