Seems to be well on the way. Glosso isn't carpeting like before but I think that was a lack of CO2 as the HC is showing some algae, so I've reduced the light period by 30 minutes and pushed the co2 up, there is plenty of flow so thats not an issue.
There are 10 more amano shrimp and 30 red cherrys sat at the LFS waiting for me to collect so they should take care of the few algae issues, I'm hoping the increase in co2 will encourage it to die off as well.
