As the title says I got incredibly lazy and have not done a water change in about a year my question is after 5 years is the tank “running itself”? Ammonia 0 nitrate 5 nitrite 0 ph 8.0 salinity 1.025 alkalinity 9.6 calcium 430 magnesium 1300 phosphate 0 are these acceptable levels for a mixed reef tank? My lfs says to keep doing what I’m doing but I’m literally not doing much ...just wondering what the pros think about this?! 72 gallon socks changed monthly filters washed out here and there skimmer is running most of the time ...ty all!
