Don't clean the gravel.
Use your vac to suck up any detritus that builds up in the glosso but don't disturb the gravel. I want to ask if you dig up the soil around your potted plants but that is a different situation since we are feeding fish in a tank and not around the potted plants. However, the effect is almost the same on the plants. The waste getting into the substrate is good for the plants. The plants, if they are growing, will take up the available ammonia to the point that you might have to add more (I do). I've been running my tanks without a real filter for years. Clear water, healthy plants, spawning fish, not too shabby.
Aquascape? I'm a crypt farmer.
It's a fine line between fishing and standing on the shore looking like an idiot.
That IS an aquascape, it's titled "The Vacant Lot".
