How to figure out tank evaporation
- Thread starter Soccer
- Start date
I put small marks on the outside of my sump at the 5, 10, 15, 20, 25, 30, and 35 gallon levels. As the water level drops from the "FULL" (30g) mark, I can judge how much is evaporating. I lose about 1 - 1.5 gallons per day. If you don't have a sump, you could make marks on your display tank, or just measure the amount of water you have to add each day.
HTH!

It's ok, I confuse my students too.
Varies from tank to tank depending on lighting, temp, surface movement and tank size. GCVT's method is a good way to estimate it over the long run.
Soccer: I think you really have a tough question: As Boogie pointed out, Tank, Lighting, Water movement, etc.. are all going to play a part. I would think that "location" would also be a big factor.
Akron OH., Guelph Ontario will be much colder that Dallas Tx. I would expect a room heater to run longer sucking moisture out of the air causing more evaporation in your tank. It happens to be 24 (I know for some of you 24 is Sun bathing weather
) in Dallas this morning ...So I'm expecting to have to add more fresh water to make up for my gas heater running longer.
The Idea would be to drip something less than what is being evaporated so you don't overflow. Another alternative would be to use a top off system that would replenish water on a "as needed" basis, rather than trying to figure out a "drip rate" Which in my view would constantly change.. I'm still working on figuring out a "top off" system. Maybe someone else can address this...
