I have to disturb that tank like once or twice a year and thats just for general plant prunning. It gets to the point where their are more plants and water-borne roots then actual water. All the plants seem to keep the water pretty low in nutrients since it use to get no real water changes. It has quite a bit of light on it so that along with the high competition from all the other plants slows those crypts down. Takes it 6 months to reach the water surface which is only 4" above the gravel.
Be aware when transferring crypts to an emersed setting they will lose their leaves. No amount of misting is going to keep submersed growth alive out of the water. The plant will switch to emersed growth eventurally... may take well over a month. Emersed growth will look much different then submersed growth. Likely narrower flat leaves. Its a hard sudden transition on the plant. When you flood the tank it will again shed its leaves and take a while to go back to submersed growth.
Also pruning... if crypt is so happy it is hitting the lid It will not likely notice the loss of some leaves. I prune crypts often if they get big and bushy and are out competing other plants. If there are a ton of them in the same area general care is the removal of older leaves as it is beneficial for the plant allowing room and light for new ones.
