    This does not mean it only affects this site, It now means that billions of images across the Web now display an error message instead of the image in question. :(

    I have a question about dosing schedule 2x week (29 galoon, 65 W for 12 hours/day+another 65W kicking in for 3 hours in the evening, CO2 mist method, heavy planted. ).

    1/4 Tsp of Potassium Nitrate
    1/16 Tsp of Mono Potassium Phosphate (KH2PO4)
    1/16 Tsp of Potassium Sulfate

    1/4 tspn of magnesium sulfate once a week by water change ,
    2 ml of Plantex CSM + Fe solution 2x week

    I change water on Thursdays and I add all macros. On Friday I add Plantex.
    I add macro and micro (in the morning) on Monday.

    As you can see I add ferts every 4 and 3 days. I`m concerned about not having stable KNO3 level in my tank.

    Should I change to every 3 day schedule? Thursday, Sunday, Wednesday, Saturday...
    If yes how much and what ferts should I add by water change?

    Re: Dosing

    Are you adding CO2 to your tank? If no, then I would stay about where you are.

    [edit] how could I miss the CO2 in your post -- sorry [edit]

    If you are, the you are close to an EI schedule (a bit low an light maybe, EI assumes 3+ wpg, if you assume you have about 23g of water then you are about 3).

    An EI schedule would call for what you are dosing 3x per week, 50% water change weekly.

    [edit] take a look at the Calculator in my signature, it provides the info you need [edit]

    You are likght on the traces, 5mls, not 2 mls and do this 3x a week, the KNO3/PO4 etc, you can add a tad more or spread it out over time, whatever is easiest for you.
