Auto Topper

[ericholcek]

Does anyone know of a good auto topper to get? It would be great if i never had to add water to my tank again except during water changes? Also how do you know how much water replace? Seems kind of tricky.
Thanks,
Eric

However much water evaporates from your tank is what needs to be replaced.
If your tank has a sump, the water level in the sump will drop as fresh water evaporates and that level just needs to be raised to where it was prior to evaporation. An auto topoff just keeps the level in the sump from dropping, keeping the salinity from changing.
The same ideas apply to a tank without a sump.
