Hi, thanks for response
Tank is 4 ft curved front, 250 L
Fish ( have not changed for 3 - 5 years ) Clown loachs, Uarus , variuos Plecs, Lemon Tetras, plus various similar ( all now safely transfered to a neighbours tank )
Pump Fluval 404 -- ( changed about 2 years ago )
gravel ( small stones ) base, several rocks, and artificial logs / branches ( again been in tank for years
Nothing has changed for years, as far as I can tell this has resulted from a routine water change; something I have done regularly for donkey's years.
water changes every 2 weeks or so, about 10 - 20% depending on requirement, must admit I had not tested water recently, but having done it today, all is within tolerances.
Water appears to be full of small particles ?????
I am totally puzzled, all the filters and media are as before
So any clues would be greatly appreciated please
