Dosing auto top off vs dosing tank directly

As well dependent on relative humidity, the amount of evaporation can change.
Would be hard to keep things consistent.

ahh, ic ic... yeah I got lots to learn

for now I plan to do a 1-2 gallon water change per week to keep my levels in check... it's only a 10 gallon AIO... but was just curious as it seemed doable to me but yeah lots of factors for sure. thanks!

I am now doing my ATO with a doser (Neptune Dos) on Channel 2 of my Neptune Dos pump. I dose Vodka on Channel 1.

Initially when calculating evaporation in exactly a 24 hour period, I measured the amount I had to manually top off. Programmed the Neptune Dos for that amount (8000 mls / 24 hours). The Dos calculated the ATO to deliver approx. 59.4 mls every 10 minutes (forgot the exact amount off hand). The Vodka is dosed at 0.9 mls every 6 hours. The water top off actually flushes the Vodka down the line (about 40 feet away from DT). I fine tuned the ATO up to 8500 mls / 24 hours and have a float switch in the sump. If too much water is added, float switch will stop dosing for a bit until level drops from further evaporation.

This setup is working VERY well. In future, if I had the need to dose more (CA or Mag.), just adding another Dos to the system and good to go.

The rate of consumption is not the same as the rate of evaporation.

Perhaps your correct. Consumption = Evaporation and what ever the fish drink. Forgot to add that...my bad

End of the day in my setup, whatever water has been displaced by whatever means has been replenished by the dosing pump. Here is a snapshot of my log...

In summer, where the water evaporate more quickly, your ATO will pump out more water to maintain the level in your sump. This will in turn, be dosing more than you would need in your tank. Vice versa, in winter time.

That's what I mean when I said 'rate of consumption is not the rate as rate of evacuation.'
