## Questions & Answers

**Q: What size tubing does this use?**
A: Thanks for your interest.   The owners manual says the model 100 uses 1/2" connections and it says the 200 and 300 uses 2/3" connections.  Not exactly sure what that translates into in UL or MM but that is what the owners manual says, 2/3" connections.

**Q: An aqurium salesman told me that having an internal heater would keep the beneficial bacteria from growing inside. Is this true?**
A: Hello. Thank you for your question. The integrated heater will not keep the beneficial bacteria from growing inside the canister. The heat will actually be beneficial to the bacteria. We hope this helps.

**Q: Will this work for a 50 gallon tank?**
A: Yes, the OASE FiltoSmart Thermo 200 is suitable for aquariums up to 55 gallons. We hope this helps. Best Regards, Your OASE Aquatic Specialist, Jennifer.

**Q: Are both intake and output 13mm?**
A: Hi,

Yes the connections are 13mm for both the inlet and outlet. Hope this helps.
