Hi guys,
This is my first "asking" post around here so please feel free to tell me if I missed something in the way you do things.
My question is about co2 and circulation which is a pretty well discussed topic, but each scape is different and I didn't find a solution for mine.
So: the scape is 3.5 months old, it's the one in picture (here just after a stem trim). It's a 80cm tank, 120L. It's the first time I tried "difficult" plants in a scape (mostly here, the Glossostigma carpet and Hydrocotyle verticillata) and I got a BBA+staghorn outbreak a month ago. Some friends and research concurred it was probably a co2 deficiency, so I increased it, changed my inline diffuser and changed my inline skimmer for the eheim to add both gazeous exchange and flow.
Now the algae tend to give up and the Glosso regrows in the left area (where the algae were the most at home). But I still have a "dead spot" on the front right corner (second picture) where the Glosso never grew (yellow leaves, scattered growth). When I put the drop checker there, near the bottom, it's dark green. On the back left it's yellow. The pH is 7.4 before co2, 6.8 at lights on (so not even the 1° drop), 6.6 at the end of the day. At that time the Guppies are gasping, the otto's are lethargic (but the neocaridinas seem ok).
All in all it seems like I have both too much and not enough co2, so I'm lost. My guess is it has to do with circulation, but I'm going textbook here (Superjet 600ex + eheim skimmer, all on the right side of the aquarium to get a nice circular flow).
So... I'm lost. I hope you'll spot something obvious that I'm missing. Thanks in advance for your advices!
Cheers,
Thomas
