The idea behind larger weekly water changes is actually more stable water parameters--by removing all the bad stuff that can't be measured or seen but that contributes to TDS [total dissolved solids] and fish stress. Plants can adapt to GH much better than fish.
1/2 water changes a week!?? Wow good thing i don't have a 55 gallon or larger, i would get sick of carrying buckets.
Anyways, I'm thinking removing the CO2 would be the best to keep a stable ph. Now since its low, what do you think would be the best way to remove it, all at once? or let it slowly run out? Im not sure how long it will take my ph to go back up to 8.2
