here is the situation. to fill my 28g nano.
i have a 30gallon holding tank for my ro/di water. i filled it up about a week ago, added powerhead and heater. the wtaer from the ro.di system comes out really soft and ph in the mid 6's. i mixed the salt slowly over the next hour(also about a week ago) until i achieved a sg of 1.023 and ph was about 8.3 then i covered it.
because of delays in recieving my live rock i didnt fill the tank yet.
so yesterday, i checked the sg and ph for the heck of it . sg was still fine at 1.023 and temp at 77 deg. but the ph seemed to drop to about 7.6. so i added a ph buffer to stabilize ph and raise kh. it went right up to 8.3 again. but this morning i checked the ph again and it dropped back down to 8.1.
can i not have mixed salt water in holding this long with nothing to stabilize the ph like argonite sand?
