    Didn't know that, but lower than 7.5 is bad for my iron filter. Good to know its good for me too though

    This is my first grow and I still read and learn.
    I bought a biotabs fertilizer that says you do not need to correct the ph and ec value.
    Biotabs did not plead hard water so I'm still trying to get that information
    They say only tap water.
    But I still wonder how to go with water. The water in my house is blurry if it is not in the coolest option but it's crystal clear then
    Is it recommended that such a cold water is going right away or waiting for a few hours

    Please help me how to deal with water and biotabs

    I made a tank in my room with a float valve and bubbler so the water refills the tank as I use it.
    My well water is freezing cold.

    However I got away with just using it for years. In fact outdoors I use the cold hose water.

    I just feel better with the slightly warmer water.

    thx you @charface
    one more question.
    if I boil water for 20-30 min will chloramin and chlorine evaporate...and if I do that does it kill something beneficial in the water ?

    I use this and it's always 6.1 pH and just add nutrients water is the key

    It takes a long time to destroy chloramines by boiling depending on volume hours with chloramine present there shouldn’t be organisms in the water the presence of chlorine usually indicates the absence of microorganisms because the chloramines kill them.
