Highways: If Napoleon would bring fiber optics

There is much talk of Napoleon in recent weeks.

would be nice to think that the work provided there was also the preparation of optical fibers along its path.

A little 'as the motorway A4.

Riorganizzazione lato sinistro

For some 'time the aquarium had a look too full, which created considerable unease aesthetic. The proper balance and use of white space is, in my opinion, essential to achieve a harmonious whole.
At the same time the latest changes made to the filter led to an absence of algae and a good balance of chemistry for the aquarium when I was a bit 'reluctant to any change ...
Finally, last week, I decided: I have identified the problem in the left side with an excessive amount of Limnophila sessiliflora. Also at the left, the woods that were too wrapped up the hardscape verso il vetro frontale riducendo la profondità della composizione. Il principale ostacolo a rimediare questa situazione era dovuto alla presenza dell'Anubias abbarbicata al legno più vicino al vetro e con le radici ben interrate.

Per prima cosa ho provveduto ad una potatura dal basso di quasi tutta la Limnophila sessiflora. Ho recuperato la parte alta delle talee per ripiantumare il lato sinistro gettando la parte bassa più spoglia.
Poi, molto lentamente, ho iniziato a spostare il legno centrale e ruotarlo verso l'interno con l'Anubias ancorata. Grazie al fondo in akadama l'impresa è stata meno traumatica del previsto.
La rotazione del legno verso l'angolo posteriore sinistro ha ridotto lo spazio per la Limnophila per cui when I've had to discard some of replanting cuttings.
I completed the work pruning the 'Hemianthus micranthemoides, foreground, and Cardamine lyrata Ceratophyllum demersum and left. After a week

Ceratophyllum demersum has already grown back excessively while the 'Hemianthus micranthemoides hard to leave but the result is obtained in discrete space and composition is remarkable.


The photo is obviously not that of a composition over because I have not yet decided on a new layout that takes advantage of the space obtained and the plants are still suffering from the drastic pruning.

Ossigeno e velocità del flusso

I read, recently, an article by Dr. Ole Pedersen, known associate of Tropica, entitled "Flow velocity Affects Internal Oxygen Conditions in the seagrass Cymodocea nodosa and available on their website . This study was carried out on a marine macrophyte but in the author's considerations also apply to freshwater macrophytes with roots.

The premise is that the macrophytes usually grow on anoxic sediments and the transport of oxygen from leaves to roots (and their radial dispersion) are needed to support aerobic metabolism and prevent the invasion of toxic substances from the sediment. During the daytime oxygen production is usually sufficient, but during the night can decline to the point that cause the plant in sofferenza.In quick study shows that under certain flow rate of water transport oxygen from leaves to roots decreases drastically.

This made me realize that the concerns that certain substrates determine anoxic zones is unfounded as this condition can be seen to be common to all funds. Moreover, whatever the fund an adequate oxygen saturation and an adequate flow velocity (around foliar apparatus) induce a release of O2 by the roots enough to oxygenate the substrate.

I asked on the forum Aquagarden if anyone had had experience in the aquarium to support of these theories. The responses were almost all favorable because:
- the introduction of pumps movement in all cases beneficial to the development of plants with immediate answers
- the presence of anoxic zones is not considered problem is in fact correctly attributed to them the conversion feature of waste substances in nutrient

However no one seems to have benefited from the introduction of oxygen through aerator, recommended among other things by Takashi Amano for the night phase of the photoperiod. It can be hypothesized that the lack of results might be due to the following factors:
- The amount of dissolved oxygen already close to saturation level in the aquarium in question.
- Low efficiency aerator with the benefits of the introduction of oxygen from the HF dispersion of CO2 due to increased water movement.

Facing the problem of summer heat with its decreasing concentration of oxygen in the tank I wanted to run tests by slightly changing the pump system: through regulator I increased the hourly flow and I applied a rubber tube on output (as in the photo) truncated obliquely so as to bring the ends under the water surface. This reduces the movement of surface and prevents loss of CO2.


Also on the top of this tube I have grafted a forza un tubo più piccolo leggermente inclinato. Questo tubo, sfruttando il minimo di effetto venturi presente, introduce dell'ossigeno nel flusso d'acqua.


Chiaramente il solo aumento della portata, che oltretutto verrà man mano ridotto dall'intasamento del materiale filtrante, non può portare gli stessi benefici di una pompa di movimento ma dovrebbe comunque migliorare la situazione.
