I just bought a 55 gallon tank and would like some advice on a hood. I am clueless on the different types of bulbs and hoods that can be used. I want to add some medium light plants such as amazon swords, etc. and was wondering what type of hood/lighting I could do. I was looking at the T5 lighting fixtures that sit high on the tank, do those need a hood cover or can it be open? What lighting could I do that can be used without the need for CO2 and won't cause too much algae in the tank? I am looking to add soil on the bottom of the tank with sand covering that. Thank you!
