Yes. They sure are. The only planted tank product that Seachem has that can be dangerous at high levels is Excel.

What is the difference between excel and regular flourish ?

Hi Peter16,

Flourish is the name of Seachem's plant product line. Seachem makes the following:
Flourish Comprehensive
Flourish Trace
Flourish Nitrogen
Flourish Phosphorus
Flourish Potassium
Flourish Excel

Flourish Excel is sold as a carbon supplement, however if used in stronger doses than recommended it also has algaecide properties.

Right now I'm dosing with Excel, and I'm waiting for my dry ferts so I can do the PPS-Pro method, but in the mean time, should I put the Excel in the tank before the lights are turned on? I know you're supposed to do this with the PPS-Pro, and it makes sense, so I'd guess you'd have to do it with any fertilizers?

Thanks Roy.
But on this website, it advertises, a bottle of "flourish"

And a bottle of "Flourish excel" Same price, different description.

Also in the chart on the first post is has dosage rates for "flourish" as well as "flourish excel"

Hi Peter16,

So I don't confuse people, I refer to Flourish as Flourish Comprehensive, which is the micronutrient additive.
BTW, I forgot Flourish Iron!

Hi csaxe21,

I dose my ferts and Excel in the morning when the lights come on, it works for me.

Peter16

I see now.
Thanks again.

I call it Flourish Comprehensive too.

Many people refer to Flourish as Trace without realizing that Seachem has a Product called Flourish Trace. It confused some people when they were told to use Flourish Trace for micro fert dosing. Calling the product simply named Flourish Flourish Comprehensive clears up the problem.

Q: Is it better to add Flourish Excel at night or in the morning based upon plant carbon uptake physiology?

A: Carbon intake is a function of photosynthesis. Based on this, it would be ideal to dose Flourish Excel during the day. But given that Flourish Excel can stay complexed as a carbon source for up to 24 hours before it dissipates, you can dose at any time of the day and the product will be available for the next 24 hours. Flourish Excel is not carbon dioxide and there is no impact on pH using Flourish Excel.


Q: Is Flourish Excel a replacement for CO2 in a planted aquarium?

A: Yes and no. It provides the same benefit as CO2, i.e. it provides the plants with a source of carbon for growth just as CO2 provides them with carbon. However CO2 by itself will give you quantitatively more growth than Excel by itself, although Excel does provide a substantial amount in comparison. If CO2 is a 10, Excel is a 6-7. Using both together provides additional benefit. One of the advantages of the Excel is no up front equipment costs and complexity of valves, hoses and regulators, etc.

quick question ... why are the ppms so spuratic for the seachem dosing guide compared to EI,PPS,PPS pro/classic?? just a newb trying to figure things out =) Ie at the end of the week in my 25 gallon I have.

No3=2.09 ppm
Fe Iron=1.76 ppm
Po4=0.14 ppm
K=4.82 ppm

I'm not gonna go into trace it gets to small to matter that much to my question. now thats also saying my plants arent growing at all meaning no uptake of ferts if you bring plants into the equation wouldnt that starve them ? or is it meant to be lean? reason I ask is that I use the seachem line and would love to be using it right =)
