If you are getting phosphorus - watch for mercury .... Don't eat the fish

If you've followed the group for any length of time, TomBarr has
mentioned
several times that phospate is one element that is usually linked to
algae
problems... it was in mine....

I never doubted that phosphate was the problem, but I always though the
water changes would fix it.
(You guys also pointed out that the nitrate level was at zero and was
stunting growth which was also correct).
It just never occured to me that the source was from the light breakage
and
not just overfeeding....
