_Dosing Regimes_

For higher light, Co2 enriched tank's that are moderately
to heavy planted.

Add o2 to your tank daily, by either air stone or surface

Dry Dosing... Use measuring spoon's found at
most department store's in the utensils section, scoop
appropriate amount and toss in the tank, simple as that!

I use to keep an old travel mug under the tank, and
keep fertilizers in large spice bottles, scoop appropriate
amount into cup, dip in tank, stir and serve.

*Dry Dosing Plantex CSM+B...
Converting 1 tablespoon to 250ml H20,
20 ml = 1/4 teaspoon of dry fertilizer.
There are 12 - 1/4 teaspoons dissolved

50% H20 change-weekly
1/4 Tsp-KN03 3x a week
1/16 Tsp-KH2P04 3x aweek
1/2 Tsp-GH booster once a week
5ml or 1/16Tsp-Trace 3x a week
1-2ml-Fe/Iron 3x a week

"If dosing a 10gal highlight C02 enriched tank,
divide above regime x2"

50% H20 change-weekly
1/2 Tsp-KN03 3x a week
1/8 Tsp-KH2P04 3x a week
3/4 Tsp-GH booster once a week
10ml or 1/8Tsp-Trace 3x a week
2-4ml-Fe/Iron 3x a week

50% H20 change-weekly
3/4 Tsp-KN03 3x a week
3/16 Tsp-KH2P04 3x a week
1 Tsp-GH booster once a week
15ml 3/16Tsp-Trace 3x a week
4-8ml-Fe/Iron 3x a week

Mixing Trace Element and Iron, Plantex CSM+B,
Fe/Iron Chelate 10%- mix 1Tbsp per 250ml water-
one cap full=5ml

Adding Sodium Bicarb/baking soda:
One teaspoon baking soda will increase the kH of
50 liters of water approx. 13 gallons by 4 degrees.

Algae Issue's?
Increase C02, even if you have to use Flourish Excel,
and decrease the light, raise it up off the tank,
burn it less hour's etc, then re-evaluate the C02.

Clean & prune, all the plant's, manually remove as much
algae as you can, good condition's will slow it's growth,
even stop growth, you will need to remove the remaining
algae by hand...

Make sure you're C02 is at optimal condition's.

GDA: Cause-Too much light, reduce intensity

BBA: Add more C02/ Reduce light intensity and or duration.

BGA: add N03 and 02/oxygen.

Fish gasping? 02 Issue's?
Increase surface movement/splash, for night time/lights out,
decrease for opposite, if having 02 issue's surface
movement/splash is good.
So a simple lift of the spray bar or lily pipe to break the
surface will remedy that.

Good article on Biochemical Oxygen Demand

BOD Low or no KH and low PH without a "crash"??

'Fertilizers for sale'


This chart is to be used "ASSUMING" proper lighting levels are
being met. Without adequate lighting, this chart can't help you.
Check your bulbs and other threads on lighting to re-assure that
you have a proper light set-up for whatever method of aquatic
gardening you wish to achieve.

The Green represents growth, in group 1 we see that plant growth
is hindered because Micro nutrients aren't being met. Although all
other demands are given in plentiful amounts, growth is stunted by
the lacking nutrient.

Group2 is meant to demonstrate low amounts of nutrient balance =
slow growth. Lighting will drive the plants to soak up nutrients to no
end. They take and take depending on the intensity of light with no
real control. If you limit the amount of nutrients you place inside the
water column and substrate, you limit their growth, no matter how
long you run your lights.

Group 3 represents maximum growth given that all nutrients are in
abundance within a level tolerable to other inhabitants. The EI
method ensures that all nutrients are provided within tolerable
amounts to fauna, as well as a bit excess for flora, all excess is
removed with a water change every week.

An example of dosing 3x a week on my 46g tank,
This is what I do.

Sunday-----Day1)Prune,Preen,Clean glass inside, 50% or more H20
change, vac/sub, 1/2Tsp-KN03, 1/8-ish/Tsp-KH2P04,1/8Tsp-K2S04,
clean glass on outside.
Monday-----Day2) 10ml Trace, 2ml-Fe
Tuesday----Day3) 1/2Tsp-KN03, 1/8ish/Tsp-KH2P04,1/8Tsp-K2S04.
Wednesday-Day4) See day2
Thursday---Day5) See day3
Friday------Day6) See day2
Saturday---Day7) Nothing or prune, or walk the dog etc.
Sunday-----Day8) See day1

Thank you cbennet for the handout you made available
to the public during your presentation at a local meeting...Kudo's!
