Multa rabdare ai cu regletele alea cu surub.. Eu m-am invatat puturos, cleme wago cu clapeta.

"Color change due to UV light
In nature, ultraviolet light waves (UV-A and UV-B) penetrate the ocean's surface but are filtered out as the light travels through the water. Both UV-A and UV-B light waves have been found to cause destruction of DNA and RNA within coral tissue. In response, many corals have made adaptations to reduce the effects of these harmful rays. These corals developed protective pigments that are often blue, purple, or pink in color. Most corals that contain these pigments come from shallow waters where the amount of UV-A and UV-B light is higher than in deeper areas of the reef.

In home reef aquariums that rely on metal halide lighting, it is important to protect corals from UV light. Coral without these protective pigments as well as shallow water corals that may have lost their pigments during transportation are especially susceptible to the effects of UV light. Fortunately, preventing any UV light from entering the aquarium is as simple as employing glass aquarium canopies and making sure the protective glass lens on the metal halide fixture is properly installed.

It is not uncommon for corals with these bright colors to adjust to the lower UV-A and UV-B conditions found within home aquariums. The loss of colorful pigmentation is not necessarily a sign of an unhealthy coral - it is simply a normal coral adjusting to its new environment."

Edit: avand in vedere ca acvariul e pornit doar de 1 saptamana nu ar fi trebuit sa am nitriti mai mari?

sorinnico wrote:Salut, am revenit cu 2 intrebari

1. Am mai achizitionat azi testele pentru ph si nitriti de la salifert. Am constatat corect mai jos?

Nitriti 0 Ph cred ca undeva intre 7.7 si 8 Nitrati intre 10 si 25



2. Astazi am bagat o pompa Jebao RW-4, imi cam balangane plutitorul de la ATO cu toate ca este protejat intr-un tub. Ceva idei cum sa rezolv?



Multumesc,
Sorin

Mie personal mi se par cam apa de ploaie.... nu am constatat nici o imbunatatire in nici un fel daca am folosit sau nu bacterii chiar si cele premium de la prodibio. Poate alti colegi de forum sunt de aceeasi parere, eu mi-am exprimat parerea mea personala bazata pe rezultatele intampinate de mine in acest hobby.
