Brown algae grow because there is too much light or too little light?
>>Not too little, but it only takes a bit, plus the right nutrients can give it what it needs. There are some who say that water with silicates will cause diatomaceous blooms, but from the bit of scientific research I’ve read, this is likely not the case (this was geared for saltwater systems). Let the algae/diatom bloom run its course, it will starve itself out, like lemmings. >Thanks very much!!! >>MOST welcome, Marcellino, and please DO send us photos of Albert and Teena. Buenos dias y Adios!
