200W Heater

[DoriReef]

I have the IM 25 lagoon and I have a 200w hyger but it is too long and sticks out of the water so I had to downgrade to a 100w. But it is not keeping the water warm enough, we keep it cool in the house and the 100w is only keeping the water around 71-73.
Does anyone know of a good 200w that is smaller than 8in long to stay in the water? I have the 200w just in the tank rn and has immediately shot temp back up to 79 in like hour and half.

No. Just use two heaters at either end of the Tank

Nicrew and Aqueon both make short heaters, I use them both they are both good brands.
