I have it growing in a 12 gallon eclipse tank with the stock 13 watt PC light. I add Excel daily and a small dose of KNO3, KH2PO4 and K2SO4 weekly as well as a weekly dose of Flourish and Flourish Iron. I also have swords, anubias, java fern, cryptocoryne pontederiifolia and sunset hygrophilia growing in this tank. Nothing grows very fast but it grows.
Unfortunately, I can't find any info online about the height of your tank but I would guess you will be OK. If you get leaves constantly shooting towards the surface you may not have enough light for the Tiger Lotus.
