Hi,
I am relatively a very new member but have been visiting this site very often. My aquarium has all the algae you can think of and also all other which you cant think of. I wonder how come my aquarium can home so many kinds of algae.
The water parameter seems fine to me. ph 6.7, GH 3deg, NO3 10 mg/l, NO2 negligible and water temp of 26-27 deg celcius.
The tank is approx 95 gallons and i am using two MH 150 watts each switched on for 5 hrs and there after two 18 watts osram fluora. for next 6 hours. I am using pressuried co2. The plants are growing very well but even better the algae.so far i have noticed black beard algae, green spot algae, dust algae, thread algae. theres another algae some what blk brown in colour and appears as small algae balls stuck to my gravel.
before i bought these MH i did my required reiki and came across with MH with ceremic techology and found their spectrum good enough for consideration. the spectrum were peaking in red and blue, 4200 k, 14000 lumens and cri of 95.
I am following estimative index for fertilisation which involves khpo4,kno3 and microsol-b.
Any one who can render some advise.
regards
