Actually Glutaradehyde is C5H8O2, that how it works as an alternative carbon source. More expensive than CO2, and causes swings in the balanced aquarium. Good to use while you do stabilize the aquarium to minimize BBA.

 


Your LFS may have a bottle of plant ferts on sale or you need to get something online. I have Osmocote+ capsules if you do not want to fertilize daily or Ei method.



Have a pic of the Downoi? Maybe under the higher lights the Downoi is staying smaller. I cannot answer this because mine got chewed by something.

 


What is your CO2 level? You can estimate the CO2 with a pH-Kh Chart or
AquariumInfo.org/co2calculator.html

I'd not use Excel till a good month or two after the tank is done, downoi tends to do poorly in new ADA AS. More water changes will help. It will recover and do fine later.
