Looking for cheap & easy auto-topoff

[wayner]

Right now I have my ro/di filter draining into a 22 gallon rubbermaid container, I want to set something up so I can have the water from the container go right to the sump, if I can do this, I might even be able to mix kalk directly in the container and cover it., I think I evap approx. 2 gallons a day, came across this on Reef Central.

What do you think, any safer/better ways?, need something simple & reliable, I'm far from a plumber.



cheap and easy autotop off

My buddy uses a litermeter on his tank and I went to buy the same until I found out that they quit making it and the new model won't be out til the end of Oct.
So after checking his out I came up with an idea.I use digital timers for my lighting and also for the pumps on my ponds and they can be set to the minute(homedepot 17$),I used one of these with a small powerhead with the exaust reduced down to airline tubing and run it around the wall in my fish tank room to the sump.I turned it on and filled a bucket with the amount I add everyday (2 gals for my tank) and timed how long it took(13 min.) to fill that much.set the timer to run for 13 minutes once a day.No float valves to stick or expensive pumps to buy,probably could be hooked to a Neilson reactor(I use a calcium reactor) total cost about 25$.I also put a mark on my sump where the water level should be so I can vissually check that the level is right and with my water testing once a week no need to add manually everyday.
