Review: Love it! - I have a 60 gallon breeder, which is 4ft long, and am running co2. I have 2 Aquaclear 70's on the back, so don't have an outflow that a canister filter provides, and obviously not able to use an inline diffuser, so needed something to disperse the co2 throughout the water column. I first bought a power head that was just way too strong, so took that out within a few minutes and started searching again. Found this and it's perfect. Pushing the co2 to the other side of my tank, but not flattening or ripping out my plants in the flow. Using it with an atomizer, which is able to be tucked right beside the outflow on this. It's also very quiet, which makes it even better.
Review: 👎👎👎👎👎👎 - The product is useless, and he sent it to me after the agreed-upon date. It arrived exactly as it looks in the photo; I think it was someone else's return.

### ⭐⭐⭐⭐⭐ Zero sound for bedroom, perfect size for 10 gallon
*by P***L on August 17, 2023*

Hello! Not a lot of online review on this product, was looking for a inside motor filter mostly for pushing water and little bit of filter (I have a lot of floating plants which helps with filteration of water). Found this and was told is silent I originally had the 35 tidal seachem which is suppose to be silent, but i can hear the motor ratting and water dropping sound (is in my bedroom across the room, but it still bothers me as, im a light sleeper). The oase 25 filter is small, very small, smaller then you think. Takes no room, but it has very powerful impellers motor so pushes water a lot, i can see my betta riding the waves across the tank. The nozzle can be rotated to change water flows if u want it lower, but i find having it on high allows one side to have high flow while other half of my tank to have lower flow. Not a lot of water filter media inside cause is very small, so you will need live plants or just do more water changes if u go that route. Personally I recommend getting floating plants like water lettuce, they eat a lot of the bad stuff in water and keep your water healthy for fish for low maintenance. The picture is only half of my 10 gallon in comparison, so realistically what a 5 gallon will look like. This filter is great if you want a completely silent filter, i can barely hear it when i have my ear up on my tank, thats how silent it is. Also great if u just wanna add water flow to avoid dead spots in tank. (Im doing a similar walstad like tank with deep substrate and a lot of plants for low maintenance). I personally really like it. It’s exactly what i wanted for my tank, is slowly coming together. Also i have 2 nerite snails, 3 ghost shrimps very active, 1 halfmoon female betta, and what used to be 7 blue shrimps, i saw 3 of them get mauled and eaten by my betta, so they just became expensive food for my betta :( . I think ghost shrimps are just smarter and way they are doing very well, i also added a flat wood with underneath dug out to give the blue shrimps a chance, haven’t seen them in a while, but i see new corpses appear from time to time so not good. I think ghost shrimp are just smarter and bigger so they face the betta and the betta respects them to not try anything funny, but blue shrimps just stands there and gets their back grabbed and gg. All 3 of my original ghost shrimps thriving while blue shrimps are getting mauled. Feels bad…
