My Water Keeps Turing Green Like 3 Days After I Do A Water change

[Gourami Swami]

I tried glass test now, actually clean water and tank water look almost same. But in tank it is softy blurred green.



I dont think so, first 1-2 hours of water chaged is normal. It started after 5-6hour during night time. btw I took some pics. it is second day after water change. Tomorrow will be last day for green water. I am sure it will be ok after tomorrow. Same as last 4-5 months.

Is that a UV sterilizer?

I was using UV 3-4 year ago but long time no any use. Green water problem for 5-6 months and just after water changes. I am sure that it will end when I restart to use UV but I really wonder the cause reason. What is the trigger for it? Can it be something expect algs? metal elements on city water? or IDK I just wonder scientific explanation.

That is weird. If it's not green in the glass I'd guess something is fueling a small green water out break in the tank when you are replenishing an element from the water change.

btw I am not alone. I checked web and found some guys they lived same problem. As you know that generally people live green water problem caused by high lightning+overfeeding+bad water contions so all titles answered with same solution suggestions. But a couple of tank owner reported same problem, "just after water change, 2-3 days green then fixing by itself". There is no really good diagnosis on this titles.
