水草情迷

吱吱co2用唔用到一個月?吱一下用到幾多個鐘呢?

好似用唔到一個月.......只用到數星期

I have tried the Tetra one. But cannot answer you whether it will last for one month, because after 10 days I cannot stand with it and finally change to pressurized CO2 bottle.

I remember (for Tetra case), the total time for diffusion for the whole bell is about 4-5 hours. It depends on how large the water flow above the bell membrane.

My advise is, save some money for CO2 bottle or , make a DIY CO2.

JJK講得對,diy co2仲好喇,成本比吱吱co2仲平

之前我都用過Tetra吱吱裝及DIY co2; 而家就用緊CO2 bottle.
1. DIY - 絕對是最平的投資, 一星期換一次.不能控制出氣多少.
2. 吱吱裝 - 應該是最貴選擇; 可用兩三個星期. 可控制出氣但要計算.
3. CO2 bottle - 開頭投資貴補充平; 充氣一次可用一個月(500g)計, 容易.
個人建議新人先用DIY, 最後才投資CO2 bottle .
