Anyone got any ideas as to why I'm finding it hard to control my PH. I use redsea reef foundation A,B,C and now I'm using waterlife PH buffer to try and drive up my PH but it's still sitting at PH7.8?
I've conducted all the norm test as follows.
Calcium: 390 just topped up to 465mg/l
Magnesium:1290 just topped up to 1390mg/l
Alkalinity 2.8meg/L Keep trying to top-up to 4.5 for my SPS
using Reef Found B
Any help or pointers would be great. I should say I norm do a 10% water change every 6 to 8 weeks.
