    Hi Folks, I'm trying to determine if two trace elements - cobalt and nickel - are required in planted aquaria. Neither of these elements are listed in the index of Ecology of the Planted Aquarium*. Referring to James' Planted Tank**, I see that cobalt is present in both Seachem Flourish and...

    Converting% Ratios in Fertilizers to Ppm

    Hello friends The% w% rates in Tropica specialized fertilizer (green) fertilizer are as follows. It is given as 5 ml per 50 liters. When I use 5 ml for a 50 lt aquarium, I wonder about the ppm values, not the% values. If there are friends who can help in the calculation and know the ppm...

    Aquarium Plants - Day/Night Cycle - Nutrient Uptake

    Hi Folks, Would I be correct in saying that aquarium plants absorb nutrients primarily (only?) during daylight hours, i.e. during photosynthesis? And does this apply be they rooted in the substrate, epiphytes or floating plants? And does it apply to all nutrients? From my dim-and-distant 'O'...

    Aquarium Plant Fertilizers - Sources of Nitrogen

    Hi Everyone, Ever since reading Diana Walstad's Ecology of the Planted Aquarium book on the topic of most plants preferring ammonium over nitrate, I have been digging deeper into this.

    How important is sulphur for aquarium plants?

    Hi Folks, Dennis Wong on his site classifies sulphur as a macro nutrient. As far as I am aware, the only macro nutrients are nitrogen, phosphorus and potassium (aka NPK). Please see: https://www.advancedplantedtank.com/adv_nutrients.html He also includes calcium and magnesium. Here I want to...

    GUIDE #2: Auto Dosing EI (Estimative Index) With AquaMedic ReefDoser 4

    Plant Nutrient Intake

    Hi Folks, I would like to better understand the mechanisms by which aquatic plants take in nutrients. Firstly, are aquatic plants equally able to absorb nutrients through their roots and leaves? Which of these do they prefer? Some plants, e.g. Anubias, are normally grown on driftwood or rocks...
