Setting up a Juwel Trigon 190

Hi, this is my first post, so please forgive any daft questions. I've read through some of the posts, but I have a couple of queries.
I have an old 4ft tank stocked mainly with botias (my wife's choice). I recently got a Trigon 190 from ebay. The tank is in great condition, but needs a thorough clean, especially as it was previously used for marines. Is there anything in particular I should do? I was going to rinse it out 3 or 4 times, wipe everything with a clean sponge, and change the filters. Do I need to change the lights? They are blue and white for marine fish, and very bright.
Once it's in place and filled and running, I will "seed" it with bogwood and rocks from the current tank, and start adding fish a few at a time after a week. Does that sound OK?
I also want to use some plants, which aren't in the current set up. What should I do to make them botia proof, and are there any you recommend?
Thanks in advance.

Welcome to TFK!!!!!!!!! so far your plan sounds great .. as for cleaning a tank i would suggest hot water and vinegar ina 50/50 ratio .. the vinegar is easily rinsed out and will not harm your future inhabitants (chemicals and or soap would leach back into the tank from the seals over time and would wipe out anything you were to put in)

i hope we can share our experiances with you and learn from yours as well.... again welcome

Thanks for that. I hadn't thought of using vinegar. I take it ordinary malt vinegar would be OK - I'll keep the Balsamic for my salad.
What filter pads do I really need? I've seen some posts saying you don't need all the ones Juwel recommend. This is new to me, as the other tank uses an under-gravel system with air columns. I'm looking forward to a quieter set up.
Can someone recommend a good on-line retailer.

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.
