Why dose ferts daily if manufactures advise weekly?

Michael W said:
I know what you mean Andy, but think about this, Tropica grows most of their plants emersed, their fertilizing regimen will be different to that of submerged growth. I'm not saying they don't know anything about submerged growth as I have seen their layouts and it clearly suggests that they know what they're doing

Just to clarify and finish this: Tropica does ofcourse not use the same formula of ferts, dosing production, as is sold for tanks !!!

Mick, do you work for Tropica? I hope this has not caused offence?

I did not wish to single them out and my question was one born purely out of curiosity as to why the consensus on planted tank forums was to dose daily but the actual manufactures of the ferts advise to dose weekly.

I have the answer now. :)
 
Absolutely no offence taken. The question was very relevant, and no business should be above questioning. If business can't argue trustworthy fore their actions, they're bound to get into trouble.........
My real problem is "balance" here, since I'm here as a hobbyist - but under (very reasonable) restrictions on UKAPS, as an employee of a comercial business!!!

Yep ......but "The Dragon" has promised to send fire at me, if I approach the limit (since I havent been able to find any exact guides !!!)

Tropica uses HEEDTA which I would assume lasts longer than gluconate or EDTA.

Interesting! I've been using gluconate and...whatever's in Easy-Life ProFito - I need to find out! Maybe I'll give Tropica a try when I run out of ProFito.

Not that I think there will be much observable difference in plant growth lol, and I don't have the ability to test how long its useful in the water for, but may as well give it a shot just in case :wacky: .
 
I know Claus C. and Troels A. personally.
I asked Claus how often should we be dosing planted tanks back in 1998 with their Trace mix.
4-5 x a week, they say 1x a week because there are so many aquariums with just one or two plants etc, so they do the conservative thing, but folks that are planted specialist, certainly need to dose more, often a lot more.

Maybe folks think the directions on the bottle where written in stone or something and common sense is not included.

I'd been larding it on back then, everyone else wondered why my tanks grew plants and rare hard to grow species so well. Claus said every tank he saw other than mine was trace limited when he traveled here. And that was back when folks had even less lighting. I have not used Tropica in about 8-10 years or so. CMS+B and then I add Fe gluconate and DTPA to that.

Tropica still one of the best commercial brands you can get after 20 some years now.

Perhaps this is why. Are we adopting the EI process with our ferts as we understand the benefits it brings?

FYI, EI was developed using Tropica Master grow(Old name for their traces).
I was using about 20 mls 4-5 x a week on my 90 Gallon, quite a bit more than the average planted tank hobbyist.
 
Agree with Tom
I have a non Co2 low light aquarium ...although i dose liquid carbon occasional to get rid of some algae on a bunch of neglected Anubis.
I dose 3 to 4 times more Ferts/Trace...each day....more than i would in a Co2 injected aquarium.
As far as i'm concerned Co2 is a Fertilizer and if its missing we should dose more ferts/trace....not less.
hoggie
 
If you look at Tropica's table matrix, you can see the differences in Relative rates of growth for Riccia with different light and CO2 levels that cover 95% of all methods used.

So you have roughly 20X difference due solely to light and CO2 levels.
Nutrients are independent in this test(eg, EI or similar scheme).
Tropica Aquarium Plants - Rådgivning - Tekniske artikler - Vandplanters biologi - Interaktioner mellem lys og CO2

There's about a dozen other papers that looked at the effects of CO2 enrichment on aquatic plants, most had 10-20X more growth for higher light.
Thus, Tropica's table is not surprising and I would agree with it and the general conclusion.
I think Excel will give you about 3-4x more growth.

So not only do they develop good products and plants...........they support the hobby aggressively, they also support good research for hobbyists that simply will not get done any other way, focusing on the main aspects of growth.
Good folks.
