when does backflow occur?
if backflow occurs after co2 injection is stopped, it is ok. a check valve will prevent backflow from reaching your co2 cylinder.
if it occurs during co2 injection, increase the co2 flowrate.

Hi Tawauboy thx for da advise, the backflow start when I off the pump dat is blowing it when I shut down da light & since Im using DIY CO2 Im worry dat it might push water into da tube when the CO2 gets weak hence I removed it and use a glass diffuser & now problem solve Im happy now thx again.
