I'd suggest dual 200w Aqueon Pro's, it's more than you'll ever need but you should never have to stress you heater and with 2 you always have a back up in case one fails. (Not that an Aqueon has ever failed on me)
Around 9 am today I turned the heater off unplugged it and plugged it back in and placed it back into the tank . When I pulled it out of the water it felt hot so I do
T know why it isn't heating. Would my Fluval FX5 have anything to do with the water not getting warm
