Although I have the 5 gal
acrylic for only 2-3 yrs, it is pretty scratched up (completely hazy looking due to fine scratches). It was my kid's tank & she used only a sponge to clean it, no scrubbing pad (not even the acrylic safe ones.) OTOH, I can keep glass looking new for years ....
80 gal FW with 30 gal DIY wet/dry/sump.
9 fancy golds, 1 hillstream loaches, 1 rubber-lip pleco (C. thomasi), 3 SAEs, small school of white cloud minnows, planted.
