when you get to know your plants better you can start dialing in the pH for each stage. Veg and early flower likes a lower pH(5.6) while later flower likes higher pH(6.1)
I bought one years ago and used it once. Way too slow and it ties you down to it. Just use a cheap pump with a pick up tube. I can empty all but around 2qt in just a few mins from a 50gal res.
If water level is dropping and ec stays the same you may have found the "sweet spot". Worry when water drops and ec rises. I worked for a long time and many harvests to find mine.

I understand what you are saying but plants like more of certain elements at different stages. By tailoring the pH to the stage it allows the plant to absorb more of what it needs when it needs it.
