Hello, im really new to this hobby, i need some advice on reef keeping. Anyone can help out please?
Qns 1: When the water evaporate, i believe we are suppose to only top up with fresh water instead of salt water right? if so, the ph level with fresh water i guess is about 7, and if u mix with your tank water does it lower your ph overall? 1st water change 20% , next day my firefish look super stress and hide at the rocks whole day, following day died. RIP.
Qns 2: When u create your own salt water by mixing reef salt + fresh water, does the ph automatically goes up to 8.3 after mixing the salt? or am i suppose to add some buffer to raise the ph?
Thank you very much in advance for those who help advise!
