水草情迷

co2 set 同 diy 出黎的co2 在品質上有沒有分別?
會唔會co2 set 出黎d co2 種草會靚d?
而diy 既 co2 比較冇咁靚架?

CO2 is CO2 and there's no difference. The major difference is:
1. You can't control the time of supply. DIY will supply 7x24; CO2 set can follow the lighting hours as there is regulator.
2. You have to frequently replace the DIY as it only lasts for 2-3 days.
3. It's difficult to control the quantity of DIY CO2 supply, i.e. bubbles per second.

thx fish fan.
如果係diy咁長期開住co2, 會唔會令水入面co2 多過o2?
d魚會唔會缺氧?
係唔係長開既關係, 我個co2 tester 長期都係黃色...
ph 會唔會影響到呢個tester?

我都系用DIY架，但系你会唔会有白色棉状物体系细化果度。我隔2日就要洗1次，有C兄话系真菌，又有人话系酒精之类的副产品。 好多人DIY既包括我都系24小时开住，D鱼都无事，穷人无办法啦！

如果驚就熄燈後打氣可也，不過，如果水草係正常生長又夠多的話，水中溶氧量係夠用到第二日。

就我所知，CO2會影响PH。PH會唔會影响 tester 就唔清楚。

Hi fish fan, agree your point No.1, but I can't find any problem on grass growing or fish living with non-stop supply of CO2.

For point No.2, if DIY correctly, it can easily last 10-20 days. You need to take out your metal tank for refill regularly! I can refill sugar and yeast anytime at home le!!

And point NO.3, it can be control up to certain extend, e.g. from 2 bubbles / sec for first 10 days - 1 bubble /sec last 10 days with correct mix.

Frankly, DIY is no problem on tank up to 24" with 1-2 bubbles / sec. But difficult to maintain more than 2 bubbles / sec for larger tank though!

thx simon & 922,
咁水草係咪會熄燈時放co2吸氧氣?

1. 我可以見d魚浮頭先打氣, 無浮頭就即係氧氣夠用, 而水草影響不大
2. 我diy 都係可以用到10-20 日, 我個係24' 缸, 我仲會整2支黎用添
3. 我都覺 糖同伊士比例可以控制出氣量, 但係溫度都會影響出氣量, 凍天果陣我俾左支暖管落去保溫

1. 24小時打住氣就唔洗怕D魚冇氣.
3. 凍天果陣我俾左支暖管落去保溫 <---- 你俾左支暖管落去樽CO2度保溫??
我將佢放入櫃,鹵仔隻牛隔離. 較時間制鹵仔開時,牛開始熱,CO2會快D. 關時又會慢番.
