Plant fertilizer?

I was reading our profile on Aponogeton (or at least one species of aponogeton), and it said that fertilizers may be needed. I don't mind spending an extra $15 or so if I can get some increased plant growth in my tank.

This is my 10g Amazon QT tank has Amazon Sword, Aponogeton, and Anacharis. I am currently using Flourish Comprehensive and it has really helped.

I am wondering if anyone has any recomendations for Fertilizers.

Thanks!

hey there!

Seachem's Comprehensive for the planted aquarium is one that experts highly recommend. I use it and my large plants and my more high maintenance plants glow leaves every week:)

I also use potassium and excel those are from Seachem also

Do you find the potassium having a noticeable impact on the plant color or growth rates? I'm using Excel and Flourish comprehensive, along with some root tabs. Still haven't got it dialed in quite right yet (1st planted tank, working with medium/med high light).

I am using comprehensive right now. Is that a fertilizer? I have heard afew bad reviews about Exel, but I can't remember why or the source.

Flourish comprehensive is a fertilizer that supplies micronutrients. Plants also require macronutrients, but I'm not expert enough to go into all that detail! Others on the forum can and have posted tons of info - Byron is an outstanding source of expertise in his posts. I'm still new to planted tanks and rapidly learning from my many mistakes! Some folks here prefer a less chemical approach, going as natural as possible. The natural approach certainly has some advantages.

For those of us who don't want to use pressurized CO2 injection to max out plant growth, but want more plant growth than the normal CO2 level provides, Excel is a chemical carbon source (to supplement natural CO2) that, combined with the right balance of lighting and additional fertilizers, is useful to increase plant growth rates. I use it daily. However, it does cost $$, it will increase maintenance due to an increased use of ferts and plant growth, and some plants don't really care for the chemical in the Excel. The chemical, if memory serves, is one of the chemicals produced by plants in an intermediate photosynthetic stage. However, the chemical can be nasty at certain concentrations so always avoid skin contact and breathing the Excel vapors (respiratory irritant). At any rate, using excel will take more work in the tank, but I do notice increased plant growth rates when using it and actually like the additional time I spend plundering in my tank to maintain it. It does makes dialing in my fertilization and light levels more difficult, but that's part of the appeal for me - playing with the variables.

excel is well known for causing fish deaths if misused, and sometime stressing fish even used properly. Algae and certain plant species hate the stuff. I've used it to cheat and get a handle on algae problems before. I would never use it long term though.

The cost of all the store bought ferts is insane IMO. Good thing for the EI method otherwise I wouldn't be keeping plants.

I mixed up my own "Flourish equivilent" liquid fertiliser.. I typically have high nitrates (40) and I suspect high phosphates, but was having a potassium deficiency. I mixed potassium and CSM+B (a micronutrient mixture) and dose it twice a week.

Anyways, yes, flourish comprehensive is a fertiliser. Root tabs may be nice though for aponogetons that you want to winter over... Never heard of wintering over actually working.

Aponogetons have a bulb, and they for the most part use the starches in the bulb to grow...

I agree with Mikaila on the Excel. Enough said on that.

To your initial question small fry: All plants need nutrients in the presence of light in order to photosynthesize (grow). The level of growth (fast, slow, etc) largely depends upon the amount of light and nutrients. Whether growing slow or fast, plants will still be healthy. But the balance between light and nutrients, and between the nutrients themselves, is crucial to this.

In natural or low-tech setups it is best to go minimal. I use Flourish Comprehensive Supplement and have done for over 2 years now, and I am very pleased with the results. It is as far as I know the only preparation containing all nutrients (aside from oxygen, hydrogen and carbon which naturally occur in the aquarium). Once a week or at most twice a week is all you need. The frequency (once or twice) depends upon the aquarium--light, fish load, type of plants.

You mentioned Aponogeton; I have had reasonably good results from aponogeton with Flourish. Long-term I would recommend substrate nutrition for this genus of plants. But they do manage with just Flourish.

My 10g QT is heavily planted. I have been using Flourish for about 2 months now and have been amazed at the results. My Aponogeton grew at an incredible rate, it is probably doubled since I started using Flourish twice weekly. I have a low-tech QT (although after a certain thread I started, I may just make it a basic, non-planted QT), and I want to start a low-tech 55g amazon tank (without the non-amazonian species like Aponogeton and Anacharis).

I have aponogeton, and I also have amazon sword temporarily growing in my QT. I can hardly tell the difference without digging at the roots a little bit to see if it has a bulb or not. I was wondering if I should use root tabs for my amazon sword as well (as I think I have seen suggested), and what brand root tab you could recomend. I guess it is Ok to ask that without changing the topic "plant fertilizer?".

Thanks all for your imput!
