## Questions & Answers

**Q: I just purchased 200 watt heater and I was wondering if I could use with the Biomaster 250?**
A: Hello Adrian,
Thanks for asking!
The HeatUp 150 heater will fit the BioMaster 250. The HeatUp 200 will fit in the BioMaster 350.
I hope this is helpful!

**Q: Will this fit inside the Oase bioplus 200?**
A: Maybe

**Q: I’m using the 350 for my 30 gallon tank. Would this be too much?**
A: It's a bit of overkill and you should pay close attention to the temps in your tank.

**Q: do i need an adaptor for the heatup 200 to fit in my oase  filtosmart 200**
A: Hello Robert,
Thanks for asking!
The Oase ThermoFit accessory kits allow HeatUp aquarium heaters to be securely fitted into FiltoSmart external aquarium filters. In this way, FiltoSmart filters can be retrofitted to be functionally identical to FiltoSmart Thermo filters. These accessories create a watertight seal necessary for use in the filter. Includes heater tube, base, centering ring and heater adapter. 
We can help you find the adapter.
