I've had my 190l trigon going since February now.
All was well till 2 weeks ago when the water became really cloudy and green water.
I done a 70% water change instead of the usual 20% and that didn't solve it it just went cloudy in a day.
I then stripped and cut back the plants incase it was them causing this issue.
I bought a second filter so it's now got 2x 190l filters running for the one tank.
Today I came home and I couldn't even see 10cm into the tank which is the worst I've seen it so far.
All the nitrites, nitrates and ammonia levels are in good order using the master test kit.
Any ideas cos I'm lost??????
I've also changed over filter sponges and bits to just incase.
