my fish tank has been cloudy for about 2 weeks now, i have done 2 water changes and the cloudiness comes back within hours of cleaning it, can any assist?

Get some safe water treatment your water is to hard

Its hard to answer questions about water without testing it i believe many places test it for free and will be happy to usually sell you a treatment that is best suited for your situation thats usually the best course of action treatment stuff isnt too much 7 or 8 dollars max usually

A sludge cleaner should do the trick

Have you had your water tested?
