    Ammonium, algae and plant nutrient ?

    I make some study about and, for now, I think plant and algae prefer NH4 if this is present without upper or low limits (of course hi percentage of NH4 are dangerous and toxic and it's a bad idea to insert it into tank) Here: http://weriguam.org/docs/tr_10.pdf one new question and interesting...

    Co2 stabilising pH

    With your KH, you can reduce PH from 7,6 to 7 (at PH7 you have 32mg/l of CO2) If you want to reduce PH you need to use Reverse Osmosis water (for reduce KH ... and GH also) For me it's not necessary to stop CO2 at night, good KH level (from 4 to 6) permit to not have any significant...

    Ammonium, algae and plant nutrient ?

    For me it's important to know if really plant need one 'minimum' level of NH4+, before use it. If it's true then the competition of, biological filtration and algae, for NH4+ are really one anti-algae instrument ... if it's false biologic filtration are one competitor for plant and algae and we...

    Ammonium, algae and plant nutrient ?

    Thanks, now I need some time to translate and study about :wink: I don't want to add NH4+ into my tank, I only think about this 'idea' for reduce algae to zero (apply it in a new tank for have more example of what I think) : imagine I have one tank with only plants and just some little fish...

    Ammonium, algae and plant nutrient ?

    Well, thanks for reply :wink: But ... I'm difficult to convince easly :lol: The 0.5 mg/l limit from which scientific research are came ? Have you some link ? Have you made some research about ? Have you make some repeatable test about ? Sorry, but I know, aquaristic users, usually make...

    Ammonium, algae and plant nutrient ?

    Hi people, this is my first post ... I hope not too hard questions :wink: About Ammonium adsorbium: plant and algae have the same minimum level necessity of Ammonium or it's different ? I think plant have minimum level more hight than algae necessity but I can't find research about. Sorry...
