I think u just want to open it fully once a day to get co2 o2 exchange. The plants breath in the co2 and exhale the o2. With the lid closed they don't get more co2 cause they use it all. Once a day should be fine at the end of your light cycle, but I may be wrong. Others chime in if I am. Yes, the plants do exhale co2 at night but I don't think enough.
Makes sense. I did just read that it may be good to keep it covered while the plants convert from submersed to emersed, but I still think open to air for a little while won't hurt. CO2 has to get in there somehow.
I think I will try to give it an hour or so once a day
Crypts!!!!!!!! They grow so quick and look so cool. Best part is once things really get going you have your own plant bank. Ive just recently started pulling plants from my emersed set up and putting them in my tanks. Zero melt on anything so far.
The Anubias I have in my emersed set up grow faster but the leaves they send out first are yellow and then turn green. I've never had an Anubias submerged so I don't know if its true both ways or not.
Brand new leave just unfolded today. Yellow as can be.
That is a beautiful choice! I've been looking at that since I was trying to ID a new ludwiga I got, i didn't get that one but Seriously think I need to do an all Ludwiga tank. It's be beautiful.
tattooedfool- Pretty sure the anubias leaves grow in green submerged, I've never seen a yellow leaf on my petite since I got it.
Yeah I'm not sure, the two kinds I have in 2 submerged tanks haven't put out any new leaves. And I had another Anubias of a different variety put out a yellow leave that has since changed to green. So only assumptions at this point
