i have a 20L but im redoing it right now. it crashed and had a 90% die off for some reson. when my nitrates, trites, ammonia, and phosphates hit 0 every thing died. weird. so im taking this time to redo it. well i do have some zoas, a mushroom, saragasum fish, gulf shrimp, lawnmower bleeny and snails. I think i might have to much light so i migh put some screen over it to cut it down some.
i posted my progress in the DIY forum on my progress so far. im redoing every thing from the ground up. new tank and every thing.
