Would you ever consider going bare bottom??
Before you discount the question right off the bat, hear me out.
Benefits of a bare-bottom tank:
- Easy to take plants out and spot-treat for algae
- Very clean environment as you can vacuum the bottom to remove most of the detritus
- Easy to rearrange plants to create a new aquascape
- Very easy to remove plants, trim them and place them back
- Replanting doesn't dump a ton of nutrients into water column as you simply remove the pot to replant
- Clay pot provide for water exchange between water column and substrate to avoid any dead spots
- Any shape of pot can be used. For example, square pots can be put side by side to create a lawn
- Easy to control feeding regimen to heavy root feeders only and not others
