Heater problem

[croydon_downunder]

My tank holds about 200 L of water.
I have a 300 W heater, turned it on to maximum and my water temp is only 26.5 C :cry:
it has been at 26.5 C for the last 12 hours.
what should i do?

Yep, time for a new heater croydon.

If that one is still under warranty, take it back and get the best heater you can afford.
