Green Water Column

[BCReefer]

3 – 4 weeks ago while adding kalk I some how managed to kill almost all of my Xenia. After scrubing the rock and cleaning out the dead Xenia, I noticed that my water was kinda yellow looking and I was getting a bit of a algae out break.

Xince then I have tried my best to scrub out the Algae and I have done 2 - 30% water changes. Only now is my water becoming clearer. When I sucked out the water the 1st time I was bloddy amazed how dirty the water was. I read in Eric Hugo’s book that yellow/greenish water means high nutrients and water changes are the simplest form to clear the problem.

No idea if this could help but I did not notice anything about water changes being mentioned.

Cheers,
