Hi,
had Staghorn algae appear about 7 days ago which i think was caused by increase in light & no increase in Co2?
Changed from 4 x 38w Trocals to 4 x 54w Trocals which on my Rio 400 gives me 2.45w per gal!
Have done water changes, increased flow & increased Co2. Yesterday Ph was reading 6.4 which is a drop from my normal ph of 6.6, today it has gone up to 6.8 is this the reaction of algae causing this?
Also, does Co2 have a shelf life as i've had my cylinder for about 4 years (content 7.2kg)
I wish i hadn't changed lights, tanks been running since 2004 with no problems but, had one of Juwel units go so thought i would upgrade!!
Any Help would be appreciated,
Regards Steve B
