This is my first tank. It is 20l Diversa tank (25cmLx30cmHx25cmD), Chihiros LED A-series 25cm 15W set on 2/7, 50W Eheim Jäger and Eheim Aquacompact 40 with Seachem Purigen. Tank was set up on 8th of March 2016.
Plants are: Dwarf Pistia stratiotes, Ceratophyllum demersum, Cladophora aegagropila, Cryptocoryne walkeri, Cryptocoryne wendtii 'Brown', Vallisneria 'Corksrew', Cryptocoryne wendtii 'Green' and Cryptocoryne 'Flamingo'.
Substrate is Rataj Profi Soil with substrate tablets.
I also use Tetra Betta Aqua Safe and Seachem Pristine. I am dosing Dennerle nano daily fertilizer, liquid CO2 from Rataj and weekly JBL Ferropol.
It is home for one Betta, 2 Cardinala japonica and about 9 another shrimps.
I am fighting with few problems. My water is hard and my vallisneria is melting from liquid CO2 dosing. Brown, green and black algae are living inside. Sadly pressured CO2 is not possible right now.
I am doing weekly water change a gravel cleaning.
If you want to help me, please do!

I will keep you updated with photos.
