Review: Good - It does as it should. I can’t comment on whether it actually helps plants grow yet as I don’t think it has been long enough.
Review: Will update when I've used it for a couple of weeks. - Not sure if it's helping the plants as I only set it up today. It's working though, I can see the c02 is going in to the tank and its worth a try for a starter with c02.

## Questions & Answers

**Q: Has anyone used this long-term?      Thoughts-?**
A: Yes I've used "one", for a year and a half. very effective for plant growth. Simple to use, however it's almost impossible to find additional CO2 cans without having to buy the whole kit.

**Q: can i use a glass diffuser instead of the 2 big plastic containers**
A: i tried using an aftermarket glass diffuser but didnt work :( i guess the pressure in the cans arent enough pressure to push through the glass. Well I also guess it depends on the type of diffuser but didnt work for me

**Q: Can anyone tell me, would this diffuser work with a 55 gallon planted aquarium? Any other hints or advise would be greatly appreciated.**
A: Hello Robert, To be honest this is what I found regarding this product.  We have thousands of products so based off of the manufacturer description this is what I found. "Gulfstream Tropical AGU00512 Ista Co2 Diffuser SetCo2 Diffuser Set A perfect CO2 supply for small planted aquarium or beginners simple to set up and operate extendable CO2 diffusing chamber provides options of CO2 supplying rate. Include 1 can pressurized liq 1 check valve, 1 CO2 diffuser 1 flexible tube.Features Ista co2 diffuser set Indisputable quality and reliability These are the most practical diffusers available "I think it is mostly for a smaller space.  55g is quite large, I believe this is better suited for small/med aquariums. Hope this helps. Gabriela

**Q: Is there replacement co2 cans?**
A: I also tried to find replacement but only could find the whole set including the diffuser. However it seems to be a good deal anyway, as the set can be compared to other brands CO2 bottles only, for a cost stand point.
