## Description

OASE Indoor Aquatics Filtosmart Thermo 100

Review: Works perfectly - This filter has been running on my 15 gallon aquascape for about 2 months. It was very easy to set up. Cleaning is as easy as can be expected for a canister filter. It runs silently. The integrated heater provides an even temperature. Flow rate is excellent. Nitrites and ammonia are zero...indicating the bio filtering is more than adequate. What more can you ask for from a canister filter. OASE makes the best filters bar none. Their customer service is reportedly exceptional...although I haven't had too use it, myself. Why anyone would give this filter a low rating is beyond my comprehension. If you need a canister filter for a small aquarium, I would not hesitate to buy one of these. For larger aquariums, however, I would use an OASE Biomaster instead...simply because of the easy-to-clean pre-filter....makes maintenance much, much easier.
Review: Full price for a Used Filter missing pieces! Not happy with desertcart - I've bought a lot of things from desertcart and I've never had a problem. Until Now. First of lets talk about the filter. So far, so good. It was easy to set up, and so far its working perfect. Nice and quiet. I've always used Fluval filters but I heard good things about this filter and decided to try something new.. So far I'm happy with it but we'll see how it holds up over time. Now the reason I give this a one star. The second the filter arrive I was disappointed. The box was all damage and looked like it had been taped back together. The filter was dirty on the outside and a bit scratched. I automatically assumed this filter was used and not brand new. Tubing was clean and the parts inside were sealed. Once I started to set it up I realized parts were missing. Parts for the Inflow and Outflow were missing, looks like a whole bag Lucky for me I was planning to use my glass pipes for the inflow and outflow so I was still able to use the filter with no problem. if I didn't have the glass pipes the filter would have been useless. Unfortunately I wasn't very patient and bought everything I needed at once, Filter, substrate, and plants and really couldn't return it and wait for a refund to get a new filter. I'm disappointed that I paid full price and got a used filter with missing parts. Luckily I was still able to use it. If the filter continues to work for a good couple of years I guess it would still be worth it. If you decide to get this filter, open it and make sure its new and that everything is there. If you get a complete filter, I think you will be very happy with it.

## 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.

### ⭐⭐⭐⭐⭐ Quiet canister with good flow and NO HEATER IN THE TANK!
*by J***E on December 14, 2023*

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.
