lighting issues moving from 55 to 75 tall

[frank98284]

I have a 55gal planted tank with swords and i am using stock fixtures with 18wx2 6700 it has been going ok but now some of the leaves are translucent i use root tabs i know i need to change to t5ho but i will be changing to a 75gal in a couple of months and the 75 is A tall and only 36 long not a 48 like the 55gal is there a light out there that will work on both the 55 and my 75 tall i can not afford to buy two lights.Do i just have to wait and buy a light for the 75 will my swords survive the wait.???


thanks for your advise

Are you dosing any other ferts? What root tabs are you using? I don't know a ton about specific plant deficiencies but it sounds more like a fert thing than a light thing and swords can be grown in low light so I would wait until you get the new tank and get a good light with that one, but your ferts have to match your lighting too
