Hi Armey,
I agree with Marauder that your
pH is a bit low. With the HA that bad you need to track down the source, probably
PO4 or
NO3. If you don't have the test kits yet your
lfs will usually test it for you. If there is a tremendous amount of HA the readings may be 0 because the algae is locking it up. Are you/was the previous owner using tap water? That's a common culprit of
PO4. You should be using
RO/DI. The other main source of
PO4 is foods.
