在論壇裡時常看見有人提起AB白點藥, 不知到那是屬於哪一種Copper? 是 IONIC Copper 還是 CHELATED Copper?
看了他的成分，是含有coppersulphate (CuSO4.5H2O) 硫酸銅
至於是不是你說的離子或是螯合物就不清楚了。
找到相關硫酸銅應用在海水魚的資料如以下：
Copper sulphate
treatment for marine parasites
----------------------------------------------------------------------------------------------------------------------------------
Copper sulphate as a fish disease treatment
Copper sulphate (sulfate) can be used to treat a range of parasites affecting marine aquarium fish. Protozoan parasites such as Crytocaryon (marine Ich), Trichodina, Amyloodium (marine velvet disease) as well as monogenean flukes – Dactylogyrus (gill flukes) and Gyrodactylus (skin fluke). It is not recommended for treating freshwater fish.
Using copper
Copper is active against many marine protozoan and monogenean parasites, but its use can be complicated. Copper is easily de-activated because it reacts with calcareous material often found in marine aquariums, i.e. coral and limestone, to form insoluble copper carbonate.
The solubility of copper is highly dependent on pH. As pH increases above 7, copper precipitates out of solution – 100x increase for every one-unit increase in pH. The danger is that should the pH of the tank drop, that is become more acidic, then the level of ‘free’ copper can quickly rise to toxic levels as the precipitated copper is re-dissolved. In addition, organic matter also binds up copper.
When treating parasite disease, the free copper level must be maintained between 0.15 - 0.20 mg/litre. If the concentration drops below this range it will not kill the parasites. If it rises above this level then it will kill the fish! Copper will also adversely affect invertebrates. Because of these complications it is advised never to treat the community tank but instead treat affected fish in a separate hospital tank. Many elasmobranchs are also killed by copper. Elasmobanchs include the sharks, skates and rays.
Dosages
A stock solution is prepared using 1 gram of copper sulphate (CuSO4.5H2O) to 250 mls distilled water. This solution now contains 1 mg copper per millilitre. The initial dose is 0.15 mg copper per litre. Therefore if the tank contains say 200 litres then the dose required will be 200 x 0.15 mgs copper = 30 grams = 30 mls of stock solution.
The copper level of the tank should be measured immediately and thereafter twice daily using a test-kit that measures in increments of at least 0.05 mg/litre. If the residual copper level in the tank drops below 0.15 mg/litre - then add additional doses of 0/05 mg/ litre of the stock solution until the optimum level is restored. Using the same example 200 x 0.05 mgs copper = 10 mgs copper = 10 mls stock solution
Copper can easily be removed by activated carbon
---------------------------------------------------------------------------------------------------------
Useful conversions are:
ppm = mg/litre i.e. 5 ppm = 5 mg / litre
mg / litre x 3.785 = mg / gall (US) i.e 5 mg / litre = 18.9 mg / gall (US)
mg/ litre x 4.546 = mg / gall (UK) i.e 5 mg / litre = 22.7 mg / gall (UK)
To convert imperial gallons to US gallons multiply by 1.2
Other useful figures:
1 ounce = 28.35 grams
1% solution =
10 ml per litre
10 gram per litre
38 gram per gall (US)
45 gram per gall (UK)
