    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?

    As mentioned be careful with iron, staghorn and bba loves iron. I learned this the hard way in my previous setup dosing iron weekly. Phosphorus, if you don't know your actual level of phosphates in the water and you over dose you gonna have big issues with algae.

    This isn't exactly true. There are multiple factors that come into play depending on your setup. Lights, c02 delivery, stocking levels of plants and fish,etc. All of this comes into play when battling algae. I battled GSA for quite some time until I read more and determined that my phosphate levels were to low compared to my nitrogen levels. Dosed phosphates and kept at 3ppm and GSA is gone. Remember, it all comes down to your setup. You have to tailor your fert regime to suit your tank. Check out plantedtank.net some good info to dig thru there.

    I actually had a look at your thread again and I didn't spot that you had cyano / BGA. I had the same on the cobra grass I had in my tank when it was cycling. I got rid of mine my by increasing the water flow in the areas I spot it. Have you got enough water flow in the areas where you have BGA? Look at one of the reason that causes BGA, "Anaerobic conditions". https://www.thesprucepets.com/cyanobacteria-blue-green-algae-1378628 then look at what Anaerobic conditions actually mean. https://www.rpi.edu/dept/chem-eng/Biotech-Environ/Projects00/biotreat/denite/robics.htm

    I'm not saying this is the reason but it might help.

    @Amakawa i hear what you say, and agree that each setup is different, but still think it’s highly unlikely that one needs to dose extra Nitrogen in a tank like lowflyers, with angels etc and moderately planted. Nitrate levels of 5 should be more than enough for his plants to grow, and elevated nitrate levels are known to cause / contribute to the cynobacteria he has been struggling with.
    I think we are actually saying more or less the same thing. Best would be to test the actual levels of macro & micronutrients before / during the high fert route, or alternatively stick to low/no ferts. My 2c

    I’ve tried Seachem Flourish Advance over the last couple of days. Was part of a Seachem bag of goodies I bought from Hawk. Defs good results, think especially useful for helping new plants establish themselves.

    I saw a video on Youtube about how using Advance is a "secret ingredient" to get plants to establish quickly - not sure how much the the phytohormones help though. I think it's more about the Calcium, Magnesium, Potassium and Phosphorous being important building blocks for plant roots.

    I did test it out a full bottle worth of the stuff in conjunction with Scape Complete over a few months, and didn't notice anything spectacular

    I used to dose by the bottle instructions and had horrible algea issues, as ratios where not correct.

    I use the EI dosing method for my tank and it works amazingly well, zero algea and the tank is crystal clear

    I dose the following, (calculations done on APSA dosing calculator)

    Nitrogen: Seachem Nitrogen 5 ml
    Phospate: Lenolax laxative 0.2ml
    Potasium: Natures no salt KCL from dischem 0.4g
    Seachem trace 0.8ml
    Calcium: Plaster of paris 1g
    Magnesium: Epsom salts 0.4g
    Aquavitro envy 0.8ml

    Flourish iron 0.2ml


    I mix all the first ingredients into a 500ml bottle with 100ml increments

    Then mix iron into another 500ml bottle with 100ml increments, this is due to the fact that the iron will react with some of the other stuff in the other bottle.

    Dosing starts on a Monday, 100ml of the iron in the morning, and 100ml of the other supplements at night.

    This lasts till friday with no dosing on Saturday and Sunday, with 50% waterchange on Sunday.


    I want to get a dosing pump soon so the daily dosing is consistant.

    IMO the method above works fine for a small tank but could become a hassle in a larger tank due to the big waterchange required everyweek.

    It is also cost effective, as most of the stuff can be bought from the pharmacy, there are even alternatives to some of the seachem stuff that you can find, but i like using them.

    Hope this helps

    :)
