    Hi

    I have a 120l tank with NO Co2 and 2x 24w T5 lamps.

    I have not much success in growing plants in the tank as they all end up getting holes, going blackish or sort of dissolving.

    I know I need fertilizer etc but I'm struggling to work out what is the best to get.

    I was looking at getting easy life profito, liquid carbon and their potassium

    Any help?

    According to Easy Life website, Profito contains no nitrates or phosphates, looks that you will additionally need to dose NPK.

    You need something like the aquascaper complete liquid plant food or tropica secialised

    I am having great success with the All in One Liquid Fert made by CO2 supermarket. It's a dry salt mixture that you simply add water to and dose the tank daily.
    Here's the info as it comes from their website:
    Key Facts
    • All-in-One Complete Aquarium Plant Fertiliser.
    • Provides all of the macro nutrients needed by plants.
    • Provides all of the micro nutrients needed by plants.
    • All-in-One solution; no need for two separate solutions.
    • Pre-made, no need for additional weighing or measurement.
    • Easy dosing.
    Description
    Any plant, whether aquatic or terrestrial, needs a variety of nutrients to grow and maintain a good state of health. In the wild these nutrients are provided by natural means but because an aquarium is a closed ecosystem those nutrients must be supplemented to maintain strong growth and good health. If those nutrients aren't supplemented the plant will eventually die, or certainly have a lacklustre appearance.

    Plants require nutrients at different rates and volume, some are required at higher volumes, such as Potassium (K), Phosphorus (P), and Nitrogen (N) - these are known as 'Macronutrients'. Other nutrients are also required, but at lower amounts or concentrations. These are know as 'Micronutrients' and include elements such as Boron (B), Copper (Cu), Iron (Fe), Manganese (Mn), Molybdenum (Mo) and Zinc (Zn).

    Sourcing, then combining all of these 'ingredients' can be time-consuming and laborious, and getting the quantities right can be worrisome. Our 'All-in-One Complete Macros and Micros Fertiliser' solves that problem by providing all of the macro and micro nutrients your plants will need for sustained growth, health and vitality. The pre-made package contains accurately-measured quantities of the following elements:

    Potassium Nitrate
    Monopotassium Phosphate
    Potassium Sulphate
    Magnesium Sulphate Heptahydrate
    Chelated Trace Elements

    E300 Ascorbic Acid and E202 Potassium Sorbate are added to prevent mould and act as an antioxidant which enables the Macros and Micros to be combined.

    The ingredients provide all of the key elements needed for high-quality plant growth, by proving the three macro elements and the many micro elements. With our 'All-in-One Complete Macros and Micros Fertiliser' you can be assured that your plants are receiving all of the nutrients needed for sustained growth, health and vitality.

    Each 5ml dose adds:
    1.5 ppm Nitrate
    0.4 ppm Phosphate
    1.6 ppm Potassium
    0.2 ppm Magnesium

    Is it okay to combine Macros and Micros?

    The reason sometimes cited for not combining these two solutions is because the Potassium Phosphate (a macro-nutrient) could react with the Iron in the micro-nutrient ingredients. To prevent this from happening, we add a small amount of E300 Ascorbic acid to lower the pH of the solution which prevents this reaction from occurring. Ascorbic acid is otherwise known as Vitamin C, which is completely safe for use in the aquarium and will not cause any harm to fish, shrimp or plants.
    Instructions
    • 30g 'All-in-One Complete Macros and Micros Fertiliser'
    • 500ml of distilled water (or boiled then cooled water).
    • Shake bottle to mix ingredients with the water.
    • Dosing: 5ml of solution per 40 litres (daily).
    It is dead easy to mix and dose and most importantly, it really works!
    I've also made my own substrate certs by mixing some of the liquid feet with powdered red clay, rolling it into balls and allowing it to harden.
    As a result, my Amazon Swords are going through the roof!

    Ok, so it looks that phosphates won't react with Iron in the bottle with ferts, but what about the reaction in aquarium when we pour all-in-one solution in the tank with alkaline water?
    I dose Fe and PO4 on alternate days just because of that.

    Ha Ha - great point. The fact that they think it is just one reaction is quite amusing. I guess they also forgot about the photo-chemical interactions also.

    Hi Folks,

    'All in One Liquid Fert made by CO2 supermarket' appears to be the same mix as that from James' Planted Tank. It even has the same name. Although James' Planted Tank website appears to be discontinued, it can be accessed from the great resource below:

    All I can add to the conversation is, I would not recommend a product unless I had used it myself and can attest to its veracity. If anyone wants to debate about chemical reactions then that's ok. I am still gonna stick to this CO2 supermarket blend cos it works! My Amazon Swords are throwing out leaves like crazy, my Anubias are really doing well and my crypts have never looked healthier! I've used several ferts, both liquid and substrate and this is gonna be my product of choice. I have also made up some substrate certs by mixing the above with pink fullers earth and rolled into balls. I chose pink instead of red so as to not overdose the iron content because the salt mix is adequate.
    I know it's not high tech like some of you guys use but do dosing works perfectly for our system and our plants and fish have never been healthier!
