Jarek's Underwater Life

After application of the eSha 2000 treatment the corydoras’ bellies got improved a bit.

I exchanged the water in the main aquarium after four weeks on 30/5.

The aquarium survived my vacation. A challenge was the high water temperature which reached over 30 °C.

The addition of phosphorus to the water brought good results. The leaves of the plants stopped...

On 26/9 I noticed that one Cardinal tetra had mold. I wanted to apply the eSha 2000 treatment but it finished.

A year has passed since I made the aquarium. Since the last water change, I’ve applied...

I came back home from Brazil on Tuesday 12/12 and found out that plants in the aquarium got grown.

I was maintaining the fertilizer dosage as I stated in my previous article.

In March, I was in France for 10 days so the Aquarium remained without my presence.

The current Echinodorus plant has approached the frontal glass. I started thinking about...

Approximately one week after moving the fish from the quarantine aquarium to the main one...

Necessity to cool LEDs using fans. Creation of own parts to fix the fans on the aluminium profiles; use of the 3D printer and corresponding chalenges.

Another hot summer is over. It seems that thanks to the active LED light cooling the temperature in the aquarium got reduced.

Recently, the cryptocoryne and vallisneria plants have grown well. I don’t know if it corresponds to small water changes every week or if I found correct dosage of fertilizer.

In December the Seachem Flourish Excel finished and I didn’t observe any effect after its application.

Visit of Aquarium of Barcelona.

Changes in the aquarium to create rocks. Filter's output current redirection. Surprising NO₃ values. Problem with an angelfish. Discovery of a quiet fans for the LED cooling.

The LED light worked on the aquarium for two years. The light intensity weakened and the epoxy coating turned yellow. I decided to change the LEDs. For the new light I used the white LEDs with CRI 98 and RGB LEDs which I placed inside the profiles with diffusers.

The NO₃ level is low. I bought new fish: Angelfishes, Serpae tetras, Siamese algae eaters, Bronze corydoras, Ram cichlids. And new plants: Cryptocoryne sp. red mi oya and Eleocharis parvulus.

Thanks to the new light the plants grow fast. In May, I started observing deformation of some plants’ leaves. NO₃ was low. Comparison of the Seachem and Easy Life fertilizers.
