So today has been a bit of a disappointing day. As you could see yesterday, my MC was not in a good way. I did my 50% water change before lights on this morning, then set the CO2 to a new level when it started at 15:00 today. I dropped it down a little as yesterday I was at yellow about an hour after lights off. I had upped it during the photoperiod as it had not gone green by lights on. Today, 3.5 hours after lights on my drop checker is only just starting to go green and its not even the right green yet, its a dark bluish green, I have therefore increased my CO2 just now to try and get enough in to the aquarium. There is no fauna in there, so I guess I should just overdose for now and try and get the plants back on track. It would seem that when I have come home during the week and seen a green drop checker and hoped all was going well, it was not going green early enough. Being here at the weekend I can see that the CO2 is not getting up to the right level when the lights come on.
I guess that is why some of my plants have suffered, it is the ones that require more CO2 that have had problems it seems. My MC was in a really poor state, so I have had to remove most of that. The two clumps closest to the front glass were not too bad, so have retained those. I also managed to pick out some individual plantlets that looked like newer healthy growth and have replanted those around the clumps. Hopefully I can keep the rest of this alive and it will fill in with some time. One of the clumps of alternanthera reineckii was totally melted, so I pulled that out too. The rest are not in too bad shape I hope, so fingers crossed.
After seeing my stems with new growth the other day I was encouraged that they were ok behind the wood, but some of them look to be melting now. I'm not sure how one can look perfect and the one that is an inch away is melting, surely they are getting the same light, CO2 and ferts in the same place? As yet I have not pulled any of the stems out, I'm hoping I can recover those as they are not as bad. I do still have 4 clumps of the stems in a little propagator, so could always transfer those in at a later date if I need to fill in any gaps from ones that don't make it.
My lower CO2 type plants look good, the anubias is putting out new leaves all the time, there is also new growth on the crypts. The ranunculous looks really good, well, one area does, its right near the front glass so must get lots more CO2, that is going really well. The two groups further back are ok, just growing slower, but not melting.
I'll post a phone pic of what is left of my MC in a minute
