How effective is the fluval 20 gram CO2 kit?

[whatsgoodm8]

Hey everyone
So I'm looking to set up a 20 gallon tank in the near future and wanted to grow some more demanding foreground plants such as pogostemon helferi and hydrcotyle tripartita so I pretty much need CO2. There's a really cheap CO2 kit by Ista similar to the fluval 20g kit but a lot cheaper, and it has the same kind of diffuser where the CO2 just sits in the container inside the tank and slowly dissolves. I was wondering how effective can this really be? Will the amount of CO2 that dissolves be enough for those plants that I mentioned? Can anyone guess approximately how many bubbles a second of C02 this would be equivalent to? Any help would be appreciated.
Thanks in advance

It would be horrible to be honest with u. Reasons being:

There is no solenoid. So u can't put it on a timer to turn on and off.

The output would fluctuate up and down as its not being controlled by a regulator. This is a main cause for BBA algae.

Cost is expensive for refills and tanks will last minimal time.

When pressure runs low I'd imagine u would get end of tank dump causing a huge rise in co2 that can gas your fish.

To be honest if your looking to go down the co2 route then it's best to get a decent setup and now have to worry about additional cost etc after.

Paintball regulators are a great cheap alternative. Aquatek regulators are a reasonable price for both big tanks and paintballs.

I've got an azoo reg on a 2.6k cylinder (5lb) running my 60g and a full tank lasts me about 3 months + and only costs me $25 to refill at my local home few store.

Hope I've helped [emoji106]
