Posted by: yinchai Posted on: 2002-03-03 19:50 我是用sera ph-plus調高液, 但用了多次,ph都是7.5左右?

Posted by: Gundaman Posted on: 2002-03-03 20:02 我都是用sera ph-plus調高液wor. 份量夠唔夠呀? 不過似乎冇一隻ph調高液可以維持長期(一個月)穩定.

Posted by: yinchai Posted on: 2002-03-03 20:16 佢寫住5ml for 20L 我個缸120L左右,下了30ml....冇反應第二日又下....到現在還是7.5左右

Posted by: yinchai Posted on: 2002-03-03 23:06 咁點將KH升高?

Tank water contains chemicals like sulfates, hydroxides, borates and carbonates that can provide buffer to keep pH at a relatively stable value. When an acid is added to the tank, pH value will be stabilized at the original value for a while if the amount of acid added is low. However, when more acid is added up to a level that all the buffer capacity is consumed, pH will drop suddenly to a low value.

The reverse is true that if your start with a tank with low pH. The pH of the tank will remain at low pH value for a while if only small amount of alkaline is added. The alkaline added is consumed by the buffering system of the tank. If more alkaline is added up to a point that all the current buffer of the tank is consumed, the pH of the tank will rise suddenly to a high pH value.

The daily increase in pH should not be more than 0.2 or it can cause stress to your fish. Therefore, starting from a pH value of 7.5, it takes at least 3 days to achieve a value of more than 8.0.

RICKY講得岩, 但點解唔買個ca reactor和ph controller, co2 去穩定ph ? 小數怕長計, 又買提升KH 液,又買PH提升液, 好浪費金錢(兩支野加埋都成舊水), 唔值得, 而且落呢D又好難控制份量, D 魚唔可以咁短時問適應一個突變的PH, 要少少咁改變先得, 不如買番個CA REACTOR ,我個隻七百幾元, 同iczfirz個隻一樣,底玩

Posted by: wheel Posted on: 2002-03-19 19:12 牛肉兄, 你個set CA REACTOR 請問係邊到有得買? 係咪同個d幾千蚊個d差唔多功效? 有無相可睇下??? 因我都有興趣set 番套平價CA REACTOR ...thx

Posted by: yinchai Posted on: 2002-03-19 19:55 鈣反應不是要加埋CO2 控制器一起用嗎 :?) iczfirz 用緊那套三千多元的.........:D

Posted by: cowmeat Posted on: 2002-04-01 19:55 計埋co2 和咪表t和 ph controller 梗係要幾千la, 我話七百幾只係ca reactor

Posted by: iczfirz Posted on: 2002-04-01 20:01 如果只係ca reactor.加co2 set. 平平地千五蚊都有交易.. 不過有時間就睇睇.. http://www.aquarium.org.hk/cgi-bin/ch/topic_show.cgi?id=509&h=1&bpg=1&age=0

Hi yinchai,

我建議你用test kits counter check 一次啦,我上次因為個pH meter 支electrode有事,讀數一直偏低,搏命加pH buffer,攪到d魚停哂口,後來覺得有d唔對路,買左set test kits一check讀數原來已經8.5,於是即刻換水,過兩日d魚先開返口,真係執返身彩.仲有呀d pH meter 要定期calibrate架!;)

Posted by: Kenny Posted on: 2002-04-05 23:08 對，PH筆又好，meter又好，建議每個月tune一次。

Posted by: yinchai Posted on: 2002-04-06 22:18 我開頭都以為PH筆有問題........ 咁就買PH Meter..... 點知原來兩樣都冇問題.......... 現在PH 7.8.....由它了.......D魚又吃得.......又生猛.....又活潑...... :P:P:P:D:P:P:P
