    Hi all,
    I am naw to the hobby, I used to research before doing anything, but currently I am in a situation that I don’t understand my water chemistry.
    I completed the cycling my 65g tank with LR; NH3 / NO2/ NO3 = 0. After 3 days, I added 5 snails, pair of small clown fish, and 1 small salarias.
    It’s three days now and I still see a a lot of hair algae, and my water chemistry looks strange!
    PH: 8.6
    KH: 5
    Ca: 500
    Mg: 1400
    PO4: 0
    NH3= 0.15
    NO2=0
    NO3=9

    How it is possible to see hight PH and low KH ? And why I see algae if both nitrate and phosphate are ok ? I did 10% water change for two days, and I am using red sea coral pro salt.

    Can anyone explain this and tell me if I am missing something?

    A few things to consider. Cycles don’t happen in 3 days unless the LR you used was fully cured. What kind of test kits are you using? Have you tested your fresh mixed water? What kind of salt and what salinity is it mixed to?

    I think you’d be well served to get a proper baseline of your salt at 1.026 (measured with a quality refractometer) and start there.

    Pics help!

    Thank you, sorry not being very clear about cycling, indeed, I saw cycle completed in three weeks, then I waited three days with zero ammonia, nitrite, and nitrate before adding any live stocks.
    I use RO water (TDS 5 ppm) to mix red sea coral pro salt to salinity (1.027).
    Measurements of my freshly prepared saltwater are
    PH: 8.3
    KH: 8
    I am using RS test kit for Ca/ Mg, and tetra for the rest.

    Your algae could be fueled by the nitrate in the water or the rock could be leaching it. Best the to do would be some 25-50% water changes to get thing back in line. Do you have fish and corals in the tank?

    As mentioned 3 small fishes and 5 snails. No corals yet. Is it safe for the fish to change up to 50% ?

    May be useful for others, searching around I found someone recommended to clean the PH meter probe in vinegar and recalibrate it. I did so and found my PH is 7.2!
    What is the best way to boost booth KH and PH ?

    You can do a 100% water change with fish only..... just match temp and salinity.

    how old is your probe? How did you calibrate?

    At the end of the day, I wouldn’t chase ph, it’s likely fine.
