Haha, I've become a father recently, so my time is quite limited all the sudden... Keeping the tank clean is already hard. Must admit my weekly water change has become a once in 2-3 weeks water change. Luckily the tank runs very well and I need to clean the glass only once every 4-6 weeks. With the Cyperus trimming is also reduced to the minimumThe tank looks great, I like the more open quality. We've missed you!
