I have my own suspicions but I thought I would ask....
I have been unable to do my weekly water change for about 2.5 weeks. The tank has been looking great and nuisance algae has been practically nonexistent. I typically have been doing 20-25% water changes weekly.Since I have a pretty good fish load and I dont dose much more than calcium I figured I really needed to do a water change.
Yesterday (last night) I was able to change out 10g of water in my 90g tank with a 20g (actual water volume) sump. So basically a 10% water change.
I currently use Instant Ocean salt, (although I am wanting to switch over to possibly Reef Crystals or other salt more formulated towards reefs).
I got home tonight and my front and side glasses were coated in green algae. For the last 1.5 weeks I have been amazed at the lack of green film algae on the glass and rocks. I have been doing large weekly water changes because of the algae issue...thinking it was a build up of nitrates. But after this "lengthy" lack of doing water changes and my decrease in algae I am coming to different conclusions.
Recently I asked about places to buy RODI H2O because I thought an out break of cyano in both mine and my girlfriends tank (at different houses, and maintained with different equipment) was to blame on the current place I buy water from.
And now this.
My thought is that the water I am currently getting is not being filtered as much as it could be...that the filters are in need of being changed. And that when I have been doing water changes I have been "dosing" phosphates or? into my system with every water change.
Does this seem accurate or is there another cause that I am not aware of?
Why would water changes with supposed RODI water cause an algae bloom? Unless it wasn't pure.
