DIY top off container

[125reefer]

so last year i was thinking of getting an ato which im still planning on getting since i got the reefkeeper lite but i wanted a way to keep my water level at a constant level.so i got a 2 gallon container and a 1/8th diameter hose with a shut off valve at the end which i siliconed on so it wont pop off.i poked a hole at the top off the cap which twisted onto container put the hose through and siliconed the hole to keep it from popping out.next i put a small hole at the top of cap so the water will flow through the hose without collapsing the container.i syphoned the water and adjusted the flow so it drips 2 drops every 5 sec or so.and it works perfect to keep my level on point all day.sure you have to fill up the container everyother day but im happy with it.and unless i forget to fill it up which i do on occasion i dont need to syphon again cause there is usually water still in the hose.just thought id share

great idea, can you post some pics of the set up.
Remember that room temparature, and lighting have a lot to do with evaporation.

Water does not evaporate the same every day. You will have salinity swings.

been doing it for a year man.everything is perfect.i estimated my total water lose and 1 gallon a day is usually the least in a day.so it lets out 1 gallon a day.the most was 1 1/2 gallons per day.

Yeah thats what I just found out. Every degree makes a difference in the evaporation. I've been lately keeping a digital thermometer in my room, just to see my room temps day to day. The temps are around 73-77 degrees Fahrenheit...also, my friend recommended that I use an aquarium calculator. Just go to google and type in aquarium calculator and enter all of your tank info...Its a great tool to keep track of ato.

Hmmmm. If it works for you good. I tried dripping ato and was never able to keep it consistant. Bought an ato unit and use a lifter pump with 1/8 airline hose...never a problem now.
