You are cycling your tank? Keep the ammonia source in until you don't get any ammonia or nitrite readings.

Ok shall do also my temp won't hold at 26 keeps dropping to 23 24 is salt water harder to heat than fresh I have a 300 watt for 300 litre I have live rock and dormant rock in the corner around the heater but water flow is good I had a back up heater that I put in when I noticed the drop. With both set at 26 it got to 25.5 then drop over night?

If your tank is cycling it generally takes anywhere from 4 weeks to months. Did you use dry or live rock? Dry or live sand? Tank size, equipment, etc etc. Any info you can give will aid in the advice we can give you.
