dosing pumps for automated water change

[onefishy]

Does anyone use dosing pumps for setting up an automated water change - where you are basically changing out small amounts of water throughout the day? how is it working for you? which dosing pumps do you use?

I use the liter meter III with remote pump for the water change. Have another liter meter on a auto top off switch to fill RO water for evaporation.

thanks! seems like doing water changes this way would be a breeze. and the ato too. i'll look into liter meter. i wonder if something cheaper like the marine color dosing pump would work for this? not nearly as nice as the liter meter, but more budget friendly.
