Which one is better? I've noticed TMG is much more expensive for the same amount, 500mL: $20 opposed to $5 for Flourish. And TMG has K, which I don't think Flourish has, but Flourish has many more trace elements. So which tends to give better results, and why is it better?

Just FYI,

Bigalsonline.com

TMG
500ml - $10.99
5L - $49.99 (THE BEST BUY !!!)

Flourish
500ml - $7.49
2L - $21.99

Personally I prefer TMG which I have been successfully using for few years.

I like TMG cause I like my buddy Claus.

I saw a table posted not too long ago where the ingredients and concentrations were posted for these two and PlantexCSM. IIRC, the Plantex and TMG were similar, and Flourish is different in composition. I alternate Plantex and Flourish.

When using TMG, would I still need to dose for trace elements seprately? Jay, have you noticed any differences in growth since the switch?

I used TMG for some time, then switched to Kent, then Flourish (primarily for the additional micros). Solely via observation (and completely anecdotally), I believe that Flourish iron doesn't remain available to plants as long as Fe in the old Kent formulation, chelated via edta.

Most of my tanks are moderately to strongly lit. I dose Flourish on a daily basis and notice a light, whitish cast imparted on water clarity on some days after dosing. It's not something just anyone would notice, but if you look at your setups daily and are familiar with their clarity it is definitely visible. I've begun dosing Flourish in the evenings (after lights out) to mitigate potential breakdown of its stabilizers and so that I don't have to see this opaqueness

In addition to Flourish, I use a couple of hydroponics-based micronutrient supplements with Fe just to cover my bases.

I am still new to this all, but I have been using Flourish and am very happy with the growth of my plants. I am interested to see which product wins the pole in the end though.

I started with Kent, did not care much for it, switched to Sera, I liked it, but cost too much, switched to TMG since EVERYONE else was using it and I did not want to make things different vs other folks I was discussing PO4 etc with.

I really liked TMG but I also really like Flourish.
I'm not quite sure which I like the best, each has a slight, subtle quality that's tough to pin down in a GENERAL term/s, much more an individual tank observation.

I add a "secret sauce" on top of the traces sometimes folks add a tad bit more Flourish iron etc.

But I'm staying with Flourish/TMG for suggestions sinc eI have folks that have only TMG around their neck of the woods and unfortuantely, I'm buds with both Claus and Greg.

So, I like them both

So both are equally good?

Flourish does not contain nitrate or phosphate per se, but it does supply a nitrogen source, the Nitrogen equivalent being 400 ppm in the bottle. Phosphorous is not available as free phosphate but as phosphate
esters (100 ppm). Flourish does in fact contain potassium (600 ppm)
but like with the iron, you wouldn't want to use Flourish as the sole
source of potassium maintenance if the potassium is heavily utilized.
