i have a 24 litres res with about 9 litres of water in it , i have 4 plants in it that are only like 5 inches tall , every 4-7 days i clean out the res and put new water in at the ph of 5.0-5.5 and every time i come back to change the water its at about 7-8 ph ... now is this normal ? should i be adding ph down everyday to keep the ph in check ? is there anyone out there that just sets their ph once and thats it lol ?
i understand plant activity increase ph levels whilst the light are on but from 5.0-5.5 to like 7-8 is a big leap
