Hello R2R members,
I have a question regarding the Tunze Osmolator Nano 3 ATO and hopefully someone might have an answer for it.
I'm looking to buy this ATO for my nano tank and planning on pairing it with the 5 gallons plastic containers as seen in this thread. I have an older model and it used a round older pump style and it fits the container opening. However the new Nano 3 uses a new pump style, as seen in the picture, so I don't know if it can fit the opening of the 5 gallons container with the opening diameter around 2.25 inches.
Does anyone own this ATO and can confirm if it will fit?
Thanks in advance for your answers!
