    Hi guys

    I have this collection of ferts. What is your experience with them? Do you dose according to instructions, or did you figure out your own way of dosing?

    I have followed instructions on bottles and kept up with 15% weekly water changes and am battling with blue cyano algae. Any ideas?

    Thanks
    Luke

    Algae loves iron xD

    Cut down on iron dosing, once a week should be fine, if plants are healthy you can dose iron once every 2 weeks.

    I loosely follow the lean dosing approached as prescribed by Filipe Oliveira.



    Filipe's fertilization routine for 80L planted tank based on Seachem Flourish range: .: Week 1 :. Monday: 5ml K Wednesday: 2ml Fe + 5ml K Friday: 5ml K Saturday: Partial water change 20-50% .: Week 2 :. Monday: 5ml K Wednesday: 2ml NO3 + 3ml PO4 Friday: 5ml K Saturday: Partial water change 20-50% .: When I'm out :. Monday: Flourish 2ml Wednesday: Flourish advance 5ml Friday: 5ml K Saturday: Partial water NONE Since the dosing pumps are of 1ml, I adjusted the dose of each product according to my needs and plant's mass.

    The following is a basic layout of the dosing regime I apply:

    Think the extra nitrogen and phosphates could contribute?
    I use Flourish, Iron and Excel.
    Interested to know why you dose extra nitrates, what are your nitrate readings?

    Thanks for all the responses.

    A new day, to be honest, I read that the growth rate of plants requires Nitrogen. Although I knew nitrates is the last stage of the nitrogen cycle, I never put the two together before purchasing. Hence, I haven't checked my nitrates reading in a while. I'll test asap.

    Thanks Toy. I'll try reducing my Iron dosage.

    My biggest concern has been the twisted leaves of my Amazon Sword.

    Yes the fish poop will provide all the nitrogen your plants need (and more), I’d stop dosing the Nitrogen and test the nitrate levels. Perhaps that product is meant for high-tech aquascapes that are very lightly stocked?
