I have recently started a new tank (new to the hobby) and I am experiencing some doubts concerning the adequate dosage of fertilizers.
Tank:
- 250L
- Medium Planted (some stems and some slow growing)
- Filter: Oase Biomaster 600 thermo
- CO2 injection
I started the tank 8 weeks ago with a Chihiros RGB90. I started dosing Tropica Premium after week 3, 2ml/day (equivalent to half the recommended dosage). After week 5 I started dosing 4 ml/day (the recommended dosage).
Meanwhile I decided to upgrade the light to a Twinstar 900SA. I was already starting to have some green spot algae on the anubias and on the driftwood and since the light upgrade this became worse.
Having read that GSA is many times related to deficiencies in Phosphates, I tested and in fact I read 0 ppm. One week ago I started dosing Tropica Specialised 8 ml/day but I haven't noticed any changes so far, GSA is still growing in the driftwood and I keep scraping it. My photoperiod is 6 hours at 100% + 1 hour ramp up + 1 hour ramp down.
Do you think I should increase the Tropica Specialised dosing even more?
Thanks in advance.
