So today i got my big shipment of stuff in the mail today, sand,salt,powerhead,test kit,hydro,heater. And i just reasized i messed up. I bout the jaguar 250 watt heater. But i dident relize the thing has a minimal and maximum water level on it, meening i cant submerge the top part of the heater. Now this would be fine exept the thing is 17 inches long any my tank is only 16 inches tall. I put the heater in the water and the water level is about and inch to low. I tried puting it at and angle to submerge the to the water line but it looks owful. So is it alright to have the water level an inch too low? Or can i fully submerge the thing sideways?
