## Description

OASE Indoor Aquatics Filtosmart Thermo 100

Review: Power not compatible with GCC - Power not compatible with GCC
Review: Quiet canister with good flow and NO HEATER IN THE TANK! - The best aspects of this filter are its noise level - pretty darn quiet, and its relatively small form factor. The best thing about it is the heater in the filter canister removing the sight-polluting heating element from the aquarium - a HUGE plus in my book. Filter is not silent. My house is very quiet, but I can hear it now as I type this review out. It is a very, very low, slight mechanical drone - not at all offensive. The not-so-great: Priming this filter is inconvenient - have to take the heater off, pour water into the little hole until it's somewhere *near* the top, but you can't fill it too much, because then when you put the heater back in, water will spill everywhere. The spraybar and intake are not pretty to look at, which brings the overall package down a notch in my view. Why build a filter to get an ugly piece of equipment out of the tank, then include a butt-ugly intake and spray bar? Something more elegant would be much more ideal. Not sure how I like the bio-media tray surrounding the heater. The space there is limited, and if you have previously colonized, larger bio media, not much of it will fit in the space there. You really have to use Oase's small bio media due to the limited size of that chamber if you want to use the middle chamber for other media types (like floss, Chemipure packets, etc). These niggles aside, this product is very well made and inspires confidence in this brand. So much so, in fact, that I just bought their little nano surface skimmer.

## 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.

Una de las mejores compras, desde el empaque se nota la calidad. Llevo un año con el filtro y funciona muy bien, mantiene limpio el estanque casero que construí a mis tortugas. Es un excelente producto de OASE.
