I have been keeping luo han fish for abt a year in my 2 ft tank. But for e past few mths i noticed that they keep on having same kind of sickness abt a few eek i replace my water. They always have same kind of white spot like cotton around their bodies and even at their eyes and become inactive. I always replace e water when this happen but since it keep on repeating no matter how many times i change e tank, i give up the luo han fish ponggol park and i brought some gold fishes and puppies etc. I replace the water abt only half of it before putting them in as i know they cant survive on purly fresh water. But the same thing happen to them n some even died n i really wonder wat hav i done wrong or miss out?
Here is my detail, I always replace e water whenever it look dirty and after replacing, i put some salt( abt 1/4 of a can of coke) which i brought from aquarium and some dip of general aid solution (e one that make water green) and also some dip of solution which keep e water surface from turning green like fungas growing. I also replace e cotton pounce at my ext filtering pump( those that is placed on top. The filter also contain some sand n ceremic stones which the aquarium owner recommand me when i complaint that my water just get easily blurr afetr a few weeks. He said this sands will help. When ever i replace my water n start e pump again, power from e sand will come out which make e tank dirty again but it will go away after night or so.

So can anyone pls advise me?

How many gallons/liters is the tank?
What type of filter do you have?
When you are cleaning the filter are you replacing all the media?
How often do you do water changes?
What are your water parameters (ammonia, nitrIte, and nitrAte)?
What fish are in there now? What size are they? How many of each?
What is the product name of the 2 solutions you are using?

I know that's a lot of questions, but I really need to know the answers before I can help you solve your problem.

I'm assuming your 2' tank is about 20 gallons. That is way too small for luo han (flowerhorns). They can get around 12" so the really need at least 55 gallons.

Goldfish require at least 10 gallons/fish but now smaller than 30 gallons.

I really think the root of your problem is overstocking, but answering those questions will help to be sure.
