## 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.

It is very easy to install and you can see the benefits in a few days. It keeps the plants with a vivid color and make them grow tall. The design allows you to control the level of CO2 inside the diffuser and consequently inside your tank, holding the plants growth if you want to.

### ⭐ It’s just bad
*by J***N on April 6, 2021*

The can last about 2 or 3 days and it does absolutely nothing for your plants. Complete waste of money

### ⭐⭐⭐⭐⭐ I’m impressed.
*by M***N on September 19, 2020*

I have a small 5 gallon planted tank and didn’t want to add pressurized co2 to a small tank, so I bought this. Works as described. I’m getting great growth since using it. I would recommend getting a better check valve as the one included allowed gas to seep out.
