*bump*
I got my osmolater and think its great, I wish I would have gotten one long before.
Supposing I were to add the calcium dispenser (in a bucket of vinegar water) though, I am worried that the top-off volume is way too fast for my small tank (20L). That is why I want to run it only at night. The current setup (in a bucket of water) seems to only need to run about 15 seconds several times a day to keep up with the water level. Do you think I would still run in to problems if I were to put the Osmo on a timer?
