2 female fighters and a male, and 2 swordtails

hi, i have put some java fern, christmas moss in my 45L tank about 2 months ago and are slowly growing, i have a 15W Glo power, i have a feeling it may be a marine white light. Is this the right light to be using?

its about 50l, i did 25% as usual. yes used a syphon in the gravel.

Could someone tell me what to do next. Ive just done a water change and realised my filter/pump wasnt working "JUWEL 280 and couldnt get it too work, so have purchased a EHIME job and then found my discus in the bottom corner lookin very sad, he has lost most of his colour to a pale/peach colour, i have used some melafix, I guess this has hapened due to the filter not working, Is there anything that i can do in the mean time or just sit and wait to see if he comes back to life?
