Water Change & Top Up

This is what I use for water changes and water top up..

Since I am keeping my tanks in aircon room.. The evaporation rate is quite a lot.. I am doing water top up approximately 3 days once.. For water change normally I do once every 2 weeks of about 10%~15% via RO DI 6-stage system and dosing of minerals for GH and TDS direct to tank (please do not try this if you are not confident because I think my shrimps are used to my water change habits)

Here is my RO DI system..

And here is my auto top up.. (It will stop topping up water once the level which I have set is reached)

(Note: RO DI will produce water of 0~1 GH and TDS of 0~3 depending on usage and lifespan of system.. But the fallback is that every 1L of RO DI water, there will be approximate 3L of 'waste' water which is the by-product of the system)
