strange, but true.
i have had several tanks in the past, but now i only have a 10gal. all
live plants, and my g/f has incorporated about 20 fish with the help of
our baby factory swordtails. anyway, we add no chems. never even checked
the water quality.
we have had this tank for about 6mos now and it is the most clear tank i
have ever seen, we even add algae tabs twice a week.
ps....the only cleaners are a placo and two otto's. i think its just
luck.
