## Description

OASE Indoor Aquatics Filtosmart Thermo 100

Review: Power not compatible with GCC - Power not compatible with GCC
Review: I knew OASE was a good company for filters but i did not know they were this good! They give you everything you need in the box including hoses that are plenty long. I love the fact that this filter also has a heater built right into it! (you can save so much space in your tank). It is also VERY QUITE! I use to have a hang on the back filter and i thought that thing was quite, BUT MAN, this one is ultra quite. Priming it took a bit longer than i thought but that was only the first time and it was fine ever since. They also give you ample media and HIGH QUAILTY sponges. Last thing about this filter is that you can tell that the company uses high precision machines and materials to make their products. Stuff that normally breaks on other filters simply wouldn't on this. Great filter!

## 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.

*by A***L on 27 October 2021*

La instalación no fue tan complicada como esperaba, la opción de tener el calentador dentro del filtro es fantástica. Es demasiado silencioso y no sólo en las noches en pleno silencio se alcanza a percibir. Fue algo tardado echarlo a andar, pero después de ello todo funciona a la perfección. No dudes en adquirirlo, vale la pena cada peso.
