That may give you some idea then? If your doing water changes at a certain level out of necessity or just as all the gear is out anyway. Just an idea. On my DT its overstocked and I ferts dose so I'm doing 40 to 50% each week. So I can't get any more fish.
How do the platys go at tank temp? I had a school that didn't do well over winter here.
