Are you carbon dosing? (CO2/Excel, etc)

Your lighting is extremely low and almost ineffective on a 55g for even 'low-light' plants for the long-term. I'd consider upgrading to at least a 2X40W T12 fixture. A Single T5HO with good reflector or a pair of PC or T5NO bulbs would be better, as well. DIY CO2 on a 55g is barely manageable, but better than nothing when the plants show symptoms of needing it. You'd just need to keep an eye on it and replace the mixture every week to keep the CO2 pumping out at a decent level. Dosing Excel would be helpful, too.

API's CO2Booster is a great product -- better that Seachem's Flourish Excel IMHO. NOw that you have so much light you need to add a lot of fast growing plants so algae doesn't over run the place. Get some stem plants -- rotala, ludwigia, hygrophilia difformis, etc and some Vals. You want your plants using the nutrients and the light, not the algae.

BTW, what size and what brand of T5HO did you get??

I would supplement phosphate. No need to add co2 or excel as that will only exacerbate the problem.
