I posted about this the other day, and things seem to be getting worse. My tank was super cloudy, now it's turning green. The perimeters are Ok except a ammonia level of .2 that I'am treating chemically. Any thoughts? Should I do a water change? If so Alot or Little? Tank is 180G with a 40g sump and fx5. 3 monos 3-5". 1 emporer at 5 " XXL pleco.
