Blackwater conditioners & JBL water tests

I just dosed my tank with half the instructed Sera Aquatan Blackwater -conditioner. Wanted to see how it lookss :) I then started doing water tests.

Will the somewhat darker colour of the water render the tests useless?

It's a 96l tank, no fish yet. Some young plants: lots of lilaeopsis + some other South American stuff.

I also gave it the first Easy Life Carbo dose just a moment ago. The pH was 7,1 a few days ago, now it measured 7,5. Is this due these ingredients or what? Or what was the daily fluctuation of pH again? Is this normal?

Everything except the pH will be unaffected by the blackwater additive... and even that might not move enough to really notice. It's mostly the same as adding driftwood and letting the tannins leach into the water or adding a bunch of almond leaves.

7.1 to 7.5 could easily be due to testing at different times of day.

I looked up the Easy Life Carbo... there is not much information about it....

"EasyCarbo is a very powerful and effective source for aquarium plants. A strong grwoth improvement is noticable after 1 to 2 weeks. Usable with or without CO2 addition. Algae will have great difficulties to sustain themselves, due to a better plant growth. Very good to combine with the universal fertilizer ProFito.The better growing plants (even Cryptocorynes or Echinodorus sp.) can compete better with algae. E.g. brush algae don't have any change and will disappear within several weeks."

I will rephrase, there is no information on it.

What exactly is this stuff?

Easy-Life EasyCarbo Plant Fertilizer
Powerful and efficient Carbon fertilizer for aquarium plants.

Easy-Life EasyCarbo promotes faster growth and natural strength of aquarium plants while acting efficiently against algae.

EasyCarbo is a powerful and efficient carbon fertilizer for all kinds of aquarium plants.
Promotes the growth of the plants with organic and not with mineral substances.

Can be applied in aquariums with or without additional CO2 fertilizer.
Increases the plant's resistability against algae and therefore contributes to the general reduction of all kinds of algae.
Very soon a strong growth spurt of the aquarium plants is noticeable.
Easy-Life EasyCarbo has even greater effect when used in combination with Easy-Life ProFito Plant Fertilizer
Economical in use: daily only 1ml per 50l water, max. 2ml per 50l water, recommended for highly planted aquariums
An overdose can be dangerous!


It's like Excel, except much cheaper.

Yah, I read that.... no ingredients, just claims of what it does. I can buy 500ml of excel for about $10... what the heck is cheap? I am sure I can get larger packaging to make it even cheaper.

Here's Seachem's listing of their product:

"Flourish Excel™ is a source of bioavailable organic carbon. All plants require a source of carbon. This is typically obtained from CO2, but, may also be derived from simple organic compounds (such as photosynthetic intermediates). The use of either CO2 injection or Flourish Excel™ does not necessarily negate the use of the other. Because the processes of producing photosynthetic intermediates and building onto them occur simultaneously, one can derive a substantial benefit with the use of Flourish Excel™ either alone or in conjunction with CO2 . The combination is particularly ideal for situations when continuing to add CO2 could result in dangerously low pH levels. Flourish Excel™ also has iron reducing properties which promote the ferrous state of iron (Fe+2), which is more easily utilized by plants than ferric iron (Fe+3).

Why It's Different

The reason plants need CO2 is to produce longer chain carbon compounds also known as photosynthetic intermediates. Photosynthetic intermediates includes compounds such as ribulose 1,5-bisphosphate, and 2-carboxy-3-keto-D-arabinitol 1,5 bisphosphate. Although the names are complicated, the structures are quite simple (5 carbon chains). Flourish Excel™ does not contain these specific compounds per se, but one that is quite similar. By dosing with Flourish Excel™ you bypass the involvement of CO2 and introduce the already finished, structurally similar compounds. It is in its structural similarity that Flourish Excel™ is able to be utilized in the carbon chain building process of photosynthesis. Simple chemical or enzymatic steps can easily convert it to any one to any one of the above named compounds (or a variety of others).

On initial use or after a major (> 40%) water change, use 1 capful (5 mL) for every 40 L (10 gallons*). Thereafter use 1 capful for every 200 L (50 gallons*) daily or every other day. Dosing may be slowly increased in high-growth aquariums. For smaller dosing please note that each cap thread is approximately 1 mL."

Even though this is far more thorough, I still wouldn't use it... I'd choose CO2 injection first if I really felt it necessary... seldom is it actually necessary and not in my case(s) anyway.
