Hey!
I am new to this forum, and just made the transition over to CO2 injection and have a few questions -
tank details: newly set up 45g bow front (my 30 gallon cracked 4 nights ago and I did an emergency tank purchase and change), fluval 306 canister filter, lots of lighting (cannot remember specs off the top of my head), I have a bunch of newer plants in my tank now that I have upgraded but I wouldn’t say it is heavily planted right now, caribsea eco-complete substrate, and a new CO2 system.
Livestock: 8 neon tetras, 2 snails (watching them like crazy due to unexpected tank change)
currently starting with 6 hour light/co2 cycles due to the tank having to cycle again, and will gradually get back to 12 hours.
Issues:
1. perimeters at the end of 6 hours of CO2: ph 6.4, KH 4. Parameters with CO2 off for 18 hours: ph 6.6 and KH 4.
I am not getting a significant change in the ph at all, wondering if lack of surface agitation is a cause? ... which leads me to problem 2.
2. A bio layer is developing on the surface of the water and won’t go away. There is water circulation below - but definitely not a lot of surface action.
question:
would increasing surface agitation correct these issues? And what would be the best option: bubbler, powerhead, spray bar?
