Extremely Fast Evaporation

I have a 75g
48' Metal Halide 250 T5 HO
(2) 15k Metal Halides
(4) 54 watt Super Actinic T5 HO bulbs

(2) 1300 GPH Powerheads

And My water evaporates just as quick as I dump It in. I find Myself Dumping in at least a little over a gallon or more a day. Its Crazy. Unless everyones Evaporates this fast.. I also have a 30g Refugium that I run simple lights on opposite from the others.. Does anyone know why my water goes down soooooo quick. I find myself going to my LFS to fill up Water jugs more than anything!!! Not saying its not worth it, but man it sucks! haha

 

Its normal.....I evaporate 5 Gall a day!

 

maybe invest in 2 glass covers over your display tank?

I know glass cuts down on par levels, but maybe help with water loss. MY 55g losses about .75-1 gallon a day too. its open top and wet/dry is open too.. if you dont want to do the glass top, then you might want to invest in a auto-top off thingy with a 5 gallon reserve so you only need to fill that every 5 days..

 

There are a lot of factors. What is the humidity (or lack there of) of your house? In winter months the house can get real dry and thus suck your water out. A humidifier would help there.

 

I evaporate a little over 1 gallon a day on the 120 open top. Its normal.

 

Yeah, thats completely normal. I just got a level loc auto top off and I am loving it. I already had my RODI hose running under the floor to my tank for easy top offs. With the level loc you hook your RODI right up to it so theres no need for an extra reservior. It has a regular float and another float with an electric solenoid. Then mine is plugged in to a timer so it has two 2 hour time frames each day to do its top off. My RODI makes 3 gallons per hour so it has more than enough time to do what it needs to do. This is also nice incase BOTH the other shut off floats malfunction. Also, it keeps the RODI unit from turning on and off a bunch of times throughout the day causing your membrane to fail prematurely. Here is what I am talking about: Products

 

Ditto. my water disappears a lot quicker in the winter as well. dry air sucks it right out.

 

Look into getting your own RO/DI unit, you won't have to make so many trips to the LFS and will save money in the long run.
