Need help

[Lunchbox209]

I Have a two bulb t5 light fixture it's the 30in coralife freshwater fixture and the bulbs on there are 18 watts each but I found some bulbs online same company same size and everything but the watts are 31 and I want to know if I can replace the 18 watt bulbs with the 31 watt bulbs

the 31 watt bulbs are T5HO's I'd your ballast isn't made to support the wattage demanded by those bulbs they may not even light up if you try them in your fixture, I'd they somehow do manage to light up I wouldn't expect the bulbs or the ballast to last very long
