PP-HK 兄

你都算醒目，有追睇我的魚缸紀綠。
呢排唔知做乜，加極 KH 粉同 PH 粉
個缸的 PH 都係跌得好快下。

洗缸後都係咁
要時時睇住
唔知同天氣轉有無關。

48"x24"x32" 上下滴溜FOT魚缸： 29.5~31度
UFO CLASSIC 150W 14000K x2 + 30W FL BLUE x2、IWAKI MX-70V-13上水泵、PINPOINT PH 錶、DE BARY 25W UV 殺菌燈 x2套、H&S150-F2001(850L 對應)化氮、SAGA ORP CONTROLLER、OZONE MAKER、大沙樽…

對我呢d新仔來說, 你個tank log梗要追睇啦, 唔係點學到o野喎。

講番正題, 你落buffer個ph同kh唔郁會唔會係份量問題, 我200L水都建議落2.5茶更喎, 不過, 有時有效未必好, 好似我咁一落完ph即彈上o左0.07, 火背即時中招起水印

, 藍吊同小丑擦身

, 咪話唔驚。

PH就話餵多o左或者加魚痾得多所以跌o者, kh都唔知點解會跌?

肥浪個問題係佢早排大爆綠水青苔, 一鑊過清理後的暫時影響, 只要勤換棉, keep 好d 個 skimmer, 遲下會冇事.

但有樣好奇怪, 就係以前個缸o既kh係11到, 有乜因素會令佢跌o左咁多呢? 不過我真係好耐都冇test過ph同kh了。另外就算今次調番佢上去, 又會唔會好快又跌番落o黎呢?

The encrusted bone of coral and coralline algae are made mostly of calcium (Ca) AND carbonate (CO3). They will pull those ions from the water. That is the reason why you need to add both of them in your tank.

Kalkwasser (lime water) is a good way to add them because it is a balanced additive of Ca and CO3. There are additives that only gives you ONE part. e.g. Kent Turbo Calcium and Liquid Calcium, only gives you the Ca part but the Kent's buffers gives you the CO3 part.

I haven't read your tank log yet, so I am not sure how/what you add as suppliments in the tank. But I think you need to adjust you lime water dosage. In addition to lime water, are you also adding the calcium additives without adding a balanced amount of buffer?

Changing water frequently will help to replenish the Ca and CO3 but dosing limewater (or calcium + buffer) should be your primary means of replenishment.

Testing the water's Ca and KH periodically will give you a picture of your tank's need. Adjust the dosage with these measurements in hand.

Our target Ca and KH concentration is over the saturation limit of water. There is another mechanism involving magnesium to prevent CaCO3 precipitating like a snow storm in the tank. Anyway, it is very close, so, adjust your dosage slowly and make sure you don't over shoot.

You may ask what happen if you over-shoot, right? Let's take kalkwasser as an example.

Kalkwasser = lime water = Ca + OH in a water solution. The solution is very alkaline. pH = 12. Obviously, if you pour too much and too quickly in you tank. Your 火背仔 will 出水印 or even die. Even if your organisms can take the beating, your tank pH will be too high (in the higher 8.x range), the saturation limit of CaCO3 will be lower. You will then have a lot of precipitation on your pump and heater. Instead of adding Ca and CO3 in the water, those level will drop and you wasted your money.

That's why we usually drip the lime water in our tank slowly. Measure and adjust the dosage.

That's it, quite simple. Most experience reefer know what to do with their tank without even knowing the underlining reason. Too bad is that most FS sales bullshits us dosing additives.

Oh, by the way, in case you wonder why I said lime water is a balanced additives. Yes, it doesn't have carbonate in it. But it will pull CO2 from the air and gives you carbonates. Just make sure you don't let it to pull CO2 before adding it in the tank, otherwise, you end up with water and a lot of CaCO3 solid in the bottle.

餵得多，水會酸，咁d CO3 離子就會先去中和d酸，咁kh(CO3離子數目)會先跌，當CO3唔夠用，ph就會跌。好似係咁啦。

Oh oh, 姚俊 beat me to it.

Forgot to add that even if you are having a FOT. The acidic biological waste will drive CO3 back to CO2 and back to the air.

明喇.........明喇.........

即係又係因為我之前貪得意餵多o左攪壞d水, 引致ph同kh下跌, 我會留意事態發展。不過, 一直都有test no2同no3, 見佢無升先加重餵飼量, 菌同ph 的關係我都仲有些少混淆。

我一直都係用kalkwasser來補充鈣, 不過無用doser, 係一次過車落去, 當然唔連d粉喇, 不過我估計我落o既份量太輕。間中有用ab水, 都係兩樽落哂。

尋晚加o左kalk, 今朝check ph8.2-3, kh又跌番至6, 今晚番去check o下 ca, 再報!

多謝兩位大俠拔刀相助

有菌，分解d垃圾、食物，水變酸，水酸了，用緊d kh，kh用到咁上下，ph就跌。
即係有菌 -> ph跌

有菌－＞PH跌, E..................咁又有d hints喎, 自從換o左底缸後no2跌o左些少, 但no3就從20幾30插到0.3, 係咪代表d菌o既活躍程度高o左? 如果呢個諗法係o岩既話, co3既用量就會大o左, 結果係kh下跌, ph受影響波動大o左。(但係穩約記得橙鈕扣縮時又好似係換底缸前喎)

而家諗緊diy個kalk doser, 希望可以將kh穩定下來, 唔該各路人馬有無成品或圖片參考o下呢。

尋晚check ca同po4:

ca 360
po4接近0
鹽度 1.021-2

總結呢幾日check水o既數值, 雖然談不上好, 除kh稍為低外, 水質似乎又唔見有大問題喎

, 睇下面...........
no2 0.2
n03 0.3
ph 8.2
kh 6
ca 360
po4 close to 0
鹽度 1.021-2

究意會係乜原因令到d生物咁呢

設備如下:
主缸 + 底缸約200L水, 3,300L上水泵一出三加1,200L潛水頭做水流
10,000k (以前用開14,000k, 這個星期換胆) 150w老仔 x 1每天開8.5hrs
藍管 x 2每天開13hrs
水冷－＞水溫keep係26度
h&s 化氮
9w uv (新換管約個多月)
tm科學鹽
生物石約70磅
鈣沙做dsb

個人習慣:
每星期換約4%水(加新水劑除氯, 隔夜打氣, 當天溝鹽)
每兩星期換白棉一次
每一至兩星期添加trace element, 鍶、鉬、碘
用kalk及ab水交替補鈣, 不定時
每天餵魚一次, 珊瑚就不定時

生物:
魚毛十條(最大三吋)、醫生蝦一隻、扁蟲唔知幾多隻
珊瑚20幾件掛

有乜唔對路地方請點醒我
