Using Flourish Products in the EI system

I've been using Flourish, Flourish Trace and Root Tabs plus Iron (0-0-3) for my ferts in all my tanks per label instructions with a weekly 50% water change, sort of a very loose interpretation of the EI method. Since I'll be moving shortly, requiring the complete tear down of all the tanks, I've decided to get serious and attempt to follow the EI method as closely as I can. However, for reasons I won't get into, I have a large quantity of both Flourish and Flourish Trace as well as the Root Tabs which makes it somewhat impractical at this point to dump them and switch to something like Watsons products. I would like to know if I can adapt the EI method to the products I currently have on hand and what additional products I would need if any to satisfy the requirements of the EI method.

The analysis of the products are as follows:

Flourish

Guaranteed Analysis
Total Nitrogen 0.07%
Available Phosphate ( P2O5) 0.01%
Soluble Potash 0.37%
Calcium (Ca) 0.14%
Magnesium (Mg) 0.11%
Sulfur (S) 0.2773%
Boron (B) 0.009%
Chlorine (Cl) 1.15%

Root Tabs plus Iron

Soluable Potash (K20) 3.0%
Magnesium (Mg) 1.0%
Sulfur (S) 3.0%
Iron Fe) 15.0%

Derived from: Potasium Sulfate, Magnesium Sulfate and Iron Sucrate


With no offense intended to anyone, I would apppreciate if this thread could be limited to discussion of the useability of the products listed (or why they couldn't used) in the EI method and what additonal products I would need to do it correctly. There are enough discussions on the merits of the EI method elsewhere, and I'm commited to using it.

Thanks in advance.

OK... im not gonna kill you with remarks of how much of a horrible algae outbreak ive had using this product, the reason i have come to believe is the fact that the nutrients in the flourish products are a bit imbalanced and hard to calculate what your tank needs when everything is mixed together in set amounts. What i will tell you is i didnt feel like spending more money than i needed to after i purchased the products and i made it work for me, and so can you. Basically i can say with experience using flourish it does work on the plants, but for some reason i could just never cut the algae part out of it. So what i did is made my own PMDD solution using regular flourish, flourish iron, and adding KNo3, and potassium (no salt) as well as epsom salt to a pop bottle and mixed it all up very good. When i first did it i added phosphates also, but there seemed to be some kind of imbalance and caused a hair algae outbreak. So for my tank i didnt need the extra phosphate. Also i upped my co2 levels, i use 4 2l bottles now on my 29 gallon tank, and i add my mixed solution to about 10-14 drops every day and i have had NO algae since i started using this method, and my plants are growing like mad and showing bright vibrant reds, pinks, and greens. Also i do 2 25% water changes every week instead of 1 massive 50% water change. Perhaps my methods are totally different and wouldnt work for everyone but the EI dosing wouldnt work for me, and this obviously does. If you want flourish to work for you i would recommend looking up information on PMDD and adding the flourish in place of the plantex and see what happens. Despite what you do its going to be a little harder to get your nutrients balanced out using nothing but flourish, and you will probably still get some algae as a result. Good luck...

Many of us use Flourish as trace, equivalent to CSM+B from gregwatson. I use a little of both. Although Flourish has SOME macros, and the root tab also contains some K, you really miss the NPK macros. Since you don't have Flourish NPK, I would suggest getting some KH2PO4 and KNO3 from gregwatson to complement your Flourish(If you have very high fish load like me, then no need for KNO3, get K2SO4 for K+ instead). Flourish Trace is called Tap Water by some because of its low concentration, you certainly can use it to supplement a little trace in addition to Flourish. Root tab won't hurt if buried carefully although many EI followers don't bother with them, relying on water column only instead. Tom Barr argues that if you see improvement from root tabs, that means your water column dosing is sub-optimal.
