I have two t5 lights in my Juwel 260 that are way past their replacement dates. Which combo will work best. I want something that's good for plants and will enhance the fishes colours, but if its a choice, plant growth is more important.
I don't know if they still do this but when Juwel first brought out tanks with T5s they used an odd length of tube so you had to use Juwel tubes and no other make. A few companies started making Juwel compatible tubes, so make sure whatever you do get will fit.
