Evaporation and weight

Johnthebaptist · Jan 14, 2013

I need some advice from some of you who have dealt with large tanks before. I am looking at an upgrade from my 30 gallon and have an option to go way bigger but want to make sure I do not bite off more than I can chew.

I am looking at a 120g with a 90g sump. Obviously the 90 would only be about half full-say 45 gallons giving me a total or 165g.

At that size do I need to be concerned about evaporation being a issue in my home?

At that size do I need to be concerned about weight being an issue on a 8 year old home with a crawl space, tank on 1st floor. There is a poured footer and several steel support poles going on concrete footers. The floor beams are composite and all look good.

Thanks

Evaporation: You are probably looking at a gallon to a gallon and a half a day. Could be higher if you run the tank hot or have fans blowing across the tank to cool

Floor Load: Insufficient information about the load...and rather complex to calculate.

I have a 120g with a 40g sump and I loose about a gallon a day in the winter and about 1.5 gallons in the summer. My house is also about 7 years old and I didn't add any extra supports.

With the age of your house I wouldn't be suprized if your floor joists are what are called TGI joists. I asked my builder about issues from the weight and he said no worries, they are engineered to hold up a huge amount of weight. If my memory serves me it was something like 3600 lbs per lineal foot.
