千萬別跟我說都轉成藍色，我會忌妒。
哈哈哈，藍色的我不是沒有，是都把藍色養回去了，不是變紫就是變綠。
我的缸也都是這樣........
絕大多數都偏紫...藍色養不起來
不好意思
一不小心方向搞錯了。以下是我之前收藏的魚友分享
Summary:
黃色 - Nitrate and Phospate needs to be low
綠色 - Iron - overdose tends to cause darkening of tissues (KZ Iron)
藍和一些紫 - require Potassium Iodide (KZ PIF)
紅，粉紅和一些紫 - require Potassium (not potassium iodide)
紫 - require Potassium Iodide/Potassium
In Detail:
綠色
Greens would be the next easiest color to tweak. Most green coloration can be achieved through the addition of an Iron Concentrate (Kents is what I use, however Iron is Iron). You must be very careful with Iron because it is also an Algae accelerator; this is why it is so important for you to get your yellows colors first (your N and P will be lowered).
Additionally, I use my yellows as indicators for my greens and blues. You’ll notice a deficiancy if your greens are brown color or they are paling in color. I start off by dosing Iron at about 1 drop per 50 usg twice a week and take note of what happens, color changes, Algae growth, until my yellow acroporas display a green shimmer (it won’t be a solid green but a shimmer of a green/yellow).
Please note, a sign of overdosing is a darkening of tissue, when this happens you have added too much iron or too much iron is being added. Another sign of overdosing is Algae growth, stop immediately and possibly do a water change if necessary. Like everything else reef, go slowly.
