+1 on the turkey baster- I used it setting up my Nuvo 8 with ActivFlora black-and every time I move a plant. I use the baster to blow the dust off, cram a square of filter floss behind the overflow on the sump and change/rinse it every hour or so. Repeat with the baster, etc. Within 2-3 hours, it sparkles.
29g heavily planted SA: driftwood, rock, currently a mess
8g Nuvo: Blue Dreams and Velvets, driftwood, java moss and crypts. A jungle.
10g 3x divided Betta planted with no Bettas, only snails. Yes, I have backslid.
