I need a recommendation for a low tech setup for a 55 gallon tank. I want to avoid CO2 if possible so I am looking for a lower wattage setup but still powerful enough to grow, crypts, tiger lotus, swords, dwarf sags, and your typical low to medium light stuff.
I found a coralife 48" dual bulb fixture. It's normal output 28 watts per bulb. I am just worried that won't be enough. The next step up I keep finding is pretty much High output which I believe would mean CO2 and that means another $200 I don't want to spend.
