Kevin in Thye Lee Heng introduce me the CO2 plates. Which can support up to 6ft tank. He told me a customer of him using it for 6 months. No problem. No complain. And no yet need to change the plates. (I believe is small tank.)

The listed price is RM95. Members able to get around RM80. Please remember, just tell him Dom - skinny guy with a spec who ask you to come over. Perhaps, you can get some discount without saying you are club member or Dom introduce. I am not sure how much he will offering you. I am just try my best to get this offer to club members.
