So am referring soaking and the ' construction of ' 180 liter aquarium in the living room : no point in banging your head after 10 months of testing of all types, including the fact PROTALON, addittivio chemicals to eradicate the algae.
In over 12 years of aquarium hobbyists of all types and I never use the Protalon or other "chemical wizardry" to defeat the algae of any kind. I always looked at the situation and with a couple of changes to the end I have always been right.

This time maybe I'm just tired, and I think that both signs must also surrender to the fact they do not understand, or rather that it is not worth continuing to "try to understand." Usually I do not do well, deepen, but after several tests some have crossed each other I have not found a remedy to the algae continued to thrive on the 2 rocks on the lawn and it has always been slow because of this (duration, intensity and quality of light, intensity current amount of fertilizer added to nitratri and phosphates, elimination of CO2, although the fund sifonamente with Fluorite).

I would also add that most likely will return home to have a little 'salt water ... in fact i had 2 small freshwater aquarium in the bathroom that carry very well, I would try something different for this 180 liters in the living room. I have not decided yet, but I'm documenting the DSB method, which I find natural and attractive.
