CO2 Tablets/Pills.

Hi people!

Just yesterday I went to get myself a pack of CO2 pills as I've alot of quries on co2 cylinder, hope you guys can help me out a little.

CO2 Tablets bought.

The main problem here is it wont dissolve nicely, but after ahwile it becomes soft and when the water current hits it, it will dismantle itself and becomes small chunk as below, it just wont dissolve away. Really unsightly.

Spot the white little chunks

There is a instruction on the box saying "Dredge up the tablet from theaquarium when co2 is completely released"

So my question is when is it totally released? When mid way I tried to take it out, it is so soft and flaky that upon touching it will dismantle into many pieces.

Please let me know if you have any experience in these tablets and how effective it is.

Cheers!

According to most, these tablets do not work.
I've tried it myself and it left too many white undissolved stuff behind. Gave up on them not long after...

Yup, Tired it and it does not really help plants grow. DIY yeast and CO2 is cheaper and more efficient and last longer than this.
Try DIY CO2 first and save up for a pressurized CO2 cylinder. Cost around $70-$80 for the most basic one with 2 L cylinder.

Or maybe you can try liquid co2... Like others always use seachem excel if I'm not wrong... Now a days there is alot of liquid co2... Can try search buy/sell as sometimes there is co2 for sale...
