Maintenance routine
Twice a week I'd replace around 40L of water to pure RO in order to compensate for water hardening, which was intense especially when scrubing the rocks from green dust.
Description
My first aquascape made with contest in mind, third planted tank in my life. I already see that I have made all the mistakes. The biggest being the slope that compressed which made my focal point does not be in the right place. I also had some issues with fertilization probably, because after 5 months, the stones have never stopped getting greenish. What I also see as failure is buying the stones via internet (no stationary shop in the area) so I ended up not having big enough main stone. Since this time I would rather travel to other city in order to see hardscape myself.
