Hi and welcome to Tropical Fish Keeping forum.
I agree with vinegar to clean the tank; then very, very thorough rinsing.
On your question of light, the tubes should be replaced. Blue light in freshwater tanks will result in algae taking over, and poor plant growth. It actually works the other way around--the plant growth will be poor in such light, and algae then takes advantage because while it is a "plant" it is well adapted to using any light unlike higher plants which need red and blue. The best planted tank light is one of the "daylight" or full spectrum tubes, with a Kelvin around 6500K. You can buy these at hardware stores for a few dollars; Sylvania, Phillips, GE all make them. Measure your existing tubes end to end (not including the prongs) and that is what you want in a T8 (assuming you have a regular fluorescent fixture; T5 is different).
You will need a new substrate, if the marine setup was coral or something similar; calcareous gravels and coral will raise hardness and pH, fine in marine or livebearer setups but not in planted tanks with other fish. A dark fine gravel works best. Dark colours are less stressful to forest fish, and a fine gravel is excellent for plant root growth.
Plants do well in tanks with Botia, I have two setups. Some Botia species do like to chew holes in Echinodorus (sword plants), don't know why, they don't seem to bother anything else.
On the filter, I am not familiar with Juwel; but generally speaking, in planted tanks you want minimal water movement which means minimal filtration. The plants do the best filtering, the filter just moves the water around. Water movement depends upon fish in the tank; while some Botia occur in faster streams, many do not and prefer quieter setups. We have fish profiles here, second tab from the left in the blue bar across the top of the screen, and info on water flow is included in these. You can find all the Botia species we include using the scientific name search, or under Cyprinids.
