Gorilla Glue auto RDWC

So this week I realized my recirculating pumps for the main rez weren't working thus I wasn't actually controlling ph or ppm properly. Taught I was at 500ppm but was at 900 so I did a complete flush with 200l of fresh Ph D water till runoff hit 100ppm. Now I fed them a new batch of 400ppm to increase to 500 and then 600 if necessary. Never the less the tent is getting crowded I'm thinking of getting the girl on the left a new home in about a week to let the girl on the right finish at its best.
