    My tank size: 122*450*500 Volume about 200L
    Dolphin C1300 filter
    Lights: Glo T5 system with 39W Sylvania Grolux Light & 39W Sylvania Marinestar 15000K light. Both have reflectors.
    plus CO2

    I have been using EI as the basis of my daily/weekly dosage program. Currently I mix the following in 2*500ml bottles.
    AM
    Phosphorus (Dosage) 60ml
    Flourish Potassium (Dosage) 25ml
    Salpeter [KNO3] (Dosage) 6ml

    PM
    Florish (Dosage) 40ml
    Flourish Trace (Dosage) 40ml
    Flourish Iron Dosage ml

    According to calculations this is the breakdown of what I am putting into the water. See Column IN
    Second Column is EI recommondations [info I got from other websites]

    IN EI Recom Left
    Phosphate (PO4) 1.377ppm 0.5-2ppm 1.98ppm
    Potassium (K) 16.644 10-20ppm 29.22pm
    Calcium (Ca) 0.280 10-30ppm 29.1ppm
    Magnesium (Mg) 0.220 2-5ppm 8.38ppm
    Sodium (Na) 0.260 52.58ppm
    Iron (Fe) 0.890 0.1ppm 0.05ppm
    Copper (Cu) 0.007 [0.015-0.15] 0.02ppm
    Manganese (Mn) 0.041 [0.02-0.8] 0.005ppm
    Zinc (Zn) 0.035 [<0.2ppm) 0.01ppm
    Boron (B) 0.024 [0.02ppm] 0.00ppm
    Nitrate (NO3) 18.460 10-20ppm 25ppm

    After the 5 day dosage and 1 day rest I take a sample to the lab. The results can been seen in the last Column marked "LEFT"

    My concern is the Calcium and Magnesium. I hardly add any but Lab results state that I have sufficient levels in my tank. Should I add more?

    All plants are flourishing but my Ludwugia Repens is not having any joy. The leaves are fairly white and growth have came to a complete standstill. Is it the Salpeter? Shoul I go back to Seacham Nitrogen?
    DSC_0543.JPG

    I am also having trouble with Hair Algea and GSA (Greens Spot Algea) Should I increase Seacham Phosphorus dosage? Lights are 06:15-08:15 & 17:15-22:15 7hours in total

    I a looking at a cheaper alternative such as Lenolax but did not like the 'other' ingredients. What is your experience with it?

    It is also known that Seacham Neutral Regulator do increase the PO4 level in the aquarium. I had 1st hand experience. I recon it is a cheaper option than Phosphorus but how safe is it to premix it with my AM EI mix?

    I hope the experts can help me on this one.

    Why are you dosing with Seachem using EI? This must be costing a fortune! EI is designed to provide more than the plants need, 50% wc and repeat. Do this with cheap ferts.

    It looks like the only thing you don't dose Seachem is Nitrogen? Why? Dose Seachem as per the bottle. That stuff works brilliantly.

    For EI I would dose with the chemicals you get from dischem i.e. Lenolax, salt petre, natures choice no salt etc

    Hi Joshua
    Indeed costing a fortune, but by mixing the stuff before hand it does safe time. Keep in mind, I had seacham products and when the Seacham Nitro was finished I replaced it with the Salpeter. I finished theSeacham Phosphorus last week only. When I was at the pharmacy on Tuesday, I was not 100% sure that the Lenolax I was holding in my hand and reading 'Enema Adult' was the correct stuff. In hind sight, it seems to be the right stuff. So I will get it when the Seacham Phosphorus is finish. I am still not convinced that Lenolax is the best option. What other options do I have?

    As the rest of my Seacham products is finish I will replace it with cheap ferts.

    PS. I have up my Phosphorus dosage and the Ludwigia Repens is looking greener.

    Most of us doing EI are using Lenolax. Helps to keep the fish regular :)

    I do not dose EI but PPS-pro . The ingrediants stay the same. If you do not want to use Lenolax use Monopotassium phosphate KH2PO4 witch you can buy from Hydroponic.co.za in Durbanville . They call it Hortimix MKP- Bloom Booster.

    The 15000k tube is the reason for your algae issues as well. Get a 8000k or 6500k instead.

    I was considering getting the Pro Flora 10000k light to replace the Marinestar in the new year.

    You guys have not said much about the amount of Ca and Mg I put in. It is way below EI recommondation however, when I test my water at a lab on day 7 I have ample in my water. Should I add more Ca & Mg to my weekly EI Dosage?

    And what is an acceptable Sodium level?

    @GroenVissie: the paleness usually indicates a nutrient deficiency. Also the 15000K light is not cutting it. I made the same mistake too, you need to change it for either 6500K or the other ones that has been advised.

    And it's Seachem, not Seacham - sorry I had to correct your spelling there :oops:

    This is my EI calculation for my tank, I add x5 into a 2L bottle and it lasts me for a whole month so I don't have to keep on making it every week:

    apsa-ferts.jpg

    I've just done some googling on nutrient deficiencies and I see it's possibly iron? Take a look at this chart.

    [​IMG]

    By the way, did you add the volume of water to your tank when doing the EI calculations? Because that is a factor towards the calculations of your EI dosing...

    Yes. For Macro's I use K2SO4(natures choice no salt),KNO3(salpeter),KH2PO4(monopotassium phosphate).
    For Micro's I use plantex CSM+B.
