Yes, I like my macros in the background, but I find I have to blow off the sand back there now. Lot of detritus gathers in the macro fields there...which, in a way, is exactly what happens in nature, and kind of the POINT. The grass slows the water flow, allowing the particulates to fall out of suspension, and the accumulated crud helps to concentrate the nutrients for the plants to take up.
This tank has been behaving itself for quite a while, and when you consider the crap I've put it through (3 full breakdowns and moves in a years time, temp fluctuations when the iceprobe crapped out), I should probably count myself lucky. I like keeping my macros as sort of a backdrop, but it's a constant battle for space that involves a lot of pruning. This comes from my wanting the best of both worlds. I think I've made it work, but keeping everything in balance is definitely a piece of work.
