Yes, the crypts would recover but I'm keen to try something new. Call me fickle...I mourn the loss of many crypts.They should recover, right?
I just removed my CO2 from my 36g and my 20g, but with my lighting, and considering that the CO2 injection has not been regular for some months now, I don't even think the plants will know the difference. I hadn't changed the canisters in a month. I think I had some moonshine when I finally opened the canisters.
Look forward to the redo. It'll be great.

I suspect your tanks will do just fine without CO2 injection. You are the TFF Queen of Low-tech!
 I have nothing on Diana Walstad!  Resident Planted Tank Lazybone of TFF is more like it!   That is all I'm good for.
 I have nothing on Diana Walstad!  Resident Planted Tank Lazybone of TFF is more like it!   That is all I'm good for.   I cut my maintenance to less than 1 hour once a week for 4 tanks!  Now this is lazyness, especially for planted tanks.  When I'm in production, it's once every two weeks!  Almost unheard of in this section of the forum with many on EI.  No 50% water changes for me, uh-uh.

   Been there done that. The horror!
