Ciao RkCLimber and tanks...

The main reason is that I wanted to keep to a minimum the heat produced by the LEDs.

Furthermore, with a current of 700mA, each LED emits about 260 lumens and in total the light emits 260 x 5 = 1300 lumens. With this amount of lumens I have a relationship lumens / liter equivalent to 1300 / 25 = 52.

The optimal ratio lumens / liter, for aquariums with fast-growing plants, is equal to 50 (read an article in italian language http://www.h2oacquariofilia.it/laluce.asp).

Ciao ciao Christian

Ciao guys,
I am happy to present a preview of the first prototype of the circuit that allows me to make "dimmable" my LED light.
The first image shows the components used and assembled:
1 - The ATMEGA168 microcontroller, allows me to manage all other circuits.
2 - The circuit (PWM LED DRIVER) drives the LED lamp. It has a PWM input that allows to set the current of the LED and then the light they emit.
3 - The keyboard used for settings various parameters.
4 - A display showing the details ...



The second image shows the box that contains the power supply, it takes as input the 220V and provides 24V DC outputs.



You can see in the video the fishes, do not get scared anymore.

I set a duty equal to D.060, this means that the leds work to 60% of the maximun power...
Now I'm looking for a suitable container where to put everything...

What do you think?

Ciao ciao Christian

Ciao guys, here's a little update... The tank situation seems to improve with the ability to adjust the light intensity

This is the first pic.


Tired of using sheets of paper to remove the surface film of water I bought the cheaper version of the ADA Vuppa: the surface skimmer Eheim skim350.
Not as nice as the Vuppa but it has its strengths:

1 - It costs much less than Vuppa
2 -Is Eheim
3 - It has the adjustable flow
4 - The entrance to the skimmer is floating and then automatically adjusted according to the height of the water
5 - Consumes only 5 watts

Here is a second pic.


And the third top view...


And the box...


What do you think?

Ciao ciao Christian

Ciao Guys, good news, the algae are in high regression.

Unfortunately, before installing the dimmer, the amount of light hitting the aquarium was much. The aquarium was managed with precision but due to other commitments I was not able to follow... As you can see I had explosion algae i'm trying to fight.

The first pic. shows the initial situation with algae:


I still decreased the intensity of light from 60% to 54% in spite of this I also note the pearling plants. This means that the luminous intensity is still good. The current flowing in the LED is equal to 540 mA

The second photo shows the current situation...


Very very well...

Finally I added the following species, for now they are small and hidden ... expect them to grow


The experiment continues...
Ciao Christian

Ciao 4f1hmi and thanks for the appreciation

The algae problem seems to have returned The tank is going well.

The daily fertilization is the following:
1 spray of ADA Brighty K
1 spray of ADA Brighty Step 2
3 ml Seachem Phosphorus
5 drops ADA ECA

As you can see I am forced to enter phosphates and iron.
Here are the photos ...

Pic. of the tank


Detail of echinodorus tenellus.


In the foreground there are: Hemianthus callitrichoides, Glossostigma elatinoides and Eleocharis sp. mini.


Another pic.
