Biocube 29-how many heaters?

[paulr]

I am starting up my tank. I have a 50, 100 and 200wt heater. I have seen where it is good to have a backup. Do I go with the 200 and maybe the 50 for a backup? Any options?

I think that's way too much. I have a 100 watt heater in my 50 gal tank and its more than enough.

Just go with the 50, biocubes run pretty warm anyway. I personally don't have one on my cube. Its always 80

Is it good to have that backup though? 2 heaters and have them lower??

My advice is would be to run two heaters both of which are rated at half your tank's size. Maybe two heaters rated for a 15 gallon. Larger heaters will have a tendency to keep warming the water even after it has reached the set temperature because the heating element inside is still warm and takes longer to cool down. Two smaller heaters will having heating elements that will cool down fast enough to not raise your temperature. And should one fail, the other one will still be working until you recognize that one has broken down. Just my 2 cents.
