I do 10 % pwcs once a week with RO
....it is a 10 gal
nano. I dont know if the water has any PO4
, but it is from the LFS
and their tanks have no algae, so I doubt it.
I have extremly high light, 9.6 WPG
. The algae problems started a 3 months ago with the addition of the light.
My params are as follows.....NO3
/4-0, PH-8.4, Alk
-2.5...I need a phospate test kit...I might just take it to the LFS
and have them check it.
My tank is about 11 months old, and is extrmely stable....I have one neon dottyback, a peppermint shrimp, and some hermits and snails, and a couple little serpent stars.
I have been battleing a flatworm problem latley by syphoning them out, but I have added no chemicals.
Other than that all is well in tank land.
