So I've set up a new tank the fluval evo which has seachem live sand and seachem life rock 52litre and am on day 25 and I'm getting nitrite and nitrate at the moment not quite cycles yet. But my oh is dropping a lot which i don't understand.
So 2 days ago my readings were
PH 7.4
ammonia 0
nitrite 2-5mg/l
nitrate 50mg/l
KH 11
phosphate 0.5
salinity 1.023
after this I did water change of 20litres using reef crystals salt.
Today I have taking readings again which are
ph 7.29
ammonia 0
nitrite 2-5mg/l
nitrate 50-100mg/l
salinity 1.024
So why is my PH so low as it should be above obviously 8.1 at least but it's massive difference to be down to 7.29 and that's after nearly a 50% water change 2 days ago and it's even less now than it was when I tested before the change 2 days ago.
Any advice on what's happening and how to fix it would be greatly appreciated thanks
