Thanks for your appreciation !
The tank is recovering after the hardest battle against algae, the shrimps and UV filter were very helpful. There is only one problem left : KH-18. This appeared because of some changes I made to the water source. It is most likely that the next acquisition I make will be an osmosis filter.
Of course a picture with my shrimps.
I changed the old gravel with manado, water parameters now: no3 15, fe 0,4, ph 7,4 , kh 18, gh 20, co2 30ppm, although I have hard water I see that some difficult plants are still growing.:nilly:
This setup is 2 months old.
Thank you!
Now I have a new setup...Photo in first day (yesterday).
Sorry, but the surface skimmer appear in picture...List plant is significant reduce to :staurogine repens, blyxa japonica, rotala macrandra and didiplis diandra.
