What's the best plan of attack? I'd ordered some H2o2 to bath the wood in to kill the algae. Just waiting for that to arrive. Then I'll crank up the co2 too. Hopefully that will help. The drop checker in the photo had just been added hence why it's still blue
Heres a couple of threads that will help your dosing of H202
BBA - Hydrogen peroxide or Flourish Excel
