I recently made a a new setup, but my plant doesn't want to start. major problem occured when I made some test using the tap water , I realized it is very high in Po4( about 3 - 4 ppm ) and very low in No3 ( 0,2 - o,3 ) , does that influence plant growth.?
My tank is 300 L , I use for now only 2 lights 54Wx 2 t5ho ,have lots of fast growing plants, my co2 is at max speed, eheim 2028 external filter, internal filter 1500L /h,.
At first I started to dose few amounts of macros also micros, but when I realized how much macro I had in tap water it was no sens for half dosing the macros. so I insted added plus 20 ppm nitrates to kind of equalate the diffrenece.
Plants seems to be blocked , they did not grow an inch in weeks , instead algaes are getting all over , especialy green fuzz on the hair grass.
Any ideas what could I do ?
