Sorry about that Tom. Here is the link to the level controller and float valve for top off:

You can't just dump lime water into your sump like RO water - it needs to be SLOWLY dripped in - otherwise your ph will go through the roof.
You can however, just add Randy's 2 part every day manually. But you should add the CA and ALK parts seperately (wait maybe 1/2 hour after you add one before you add the other). Otherwise you will have a "snowstorm" in your tank (believe me, I just had this happen in my SW mixing container). I use pumps and timers to automate the whole process so I don't have to worry when I'm not home. The timers go down to the minute - so I can drip CA or ALK in a minute intervals throughout the day. I bought these timers on ebay - they work great.
I hope this helps to clarify. If not, let me know.
