Water evap question

[aceer15]

What size tank do you have and how much water do you top off with how often?

180 + 30 gal in sump. Evaporates 5 gallons in 2-3 days. I have a 25 gal auto top off that I fill every week when I get around to it. But it could go 2 weeks.

I say about 130 total gallons and i use a little under 10 gallons a week. I fill my ato container every monday

My big tank, about 150 gallons total & it uses about 10 gallons a week. My little tank, about 15 gallons after displacement & uses about 2.5 gallons a week.

About 450 gallons total. Probably 25 gallons a week now that I went to LEDs from mh. Was about 40g per week.

I use to go through a gallon to a gallon and a half every day on my 90g. When my pump needed replacing, I went to something with a little lower flow, now I'm only topping off three or four gallons a week. The change in flow made a big difference.

About 70 gallons over all and my ATO goes through about 6 or 7 gallons a week. My 29 gallon biocube loses less than 1/2 a gallon per week.

Thank you everyone for the replies!

Very interesting about different light types and the amount of flow from the return pump
