i do frequent small changes in my 125 just out of ease. I evaporate apx 2 gallons per day so it is just as easy to replace 5 as it is 2. i run 2 r/o at night
one into an empty 5 gallon bucket. the other into another 5 gallon bucket
both fill up over night. a third bucket is my makeup. i always have 5 gallons of makeup, and 5 gallons of fresh r/o. every day i take out 3 gallons plus the 2 gallons that evaporate. i put in 2 gallons fresh r/o and 3 gallons make-up

i am doing a 3 gallon water change daily 20+ gallons per week apx 20% weekly change. takes me about 10 min per day and seems to work for me
