Above: brown algae (Diatoms) and plant melt is common in new tanks. When starting a a new tank, it is common for users to have seemingly ‘perfect’ water parameters and still face significant plant melt and algae. This is because the microbial (“beneficial bacteria”) community isn’t established yet. It is hugely important, but cannot be […]
The best LED units for planted tanks in 2021
