I know there's a couple of threads about this already, but I need to know something very specific.
This is what happened. About a week ago I started running my T5s on a timer, actinic, day and Lunar (all night lunar), three days later I added a blue tang and a clownfish. I bough some tiny pellets for the tang, in fact it was these pellets
New Life Anti-Parasitic Pellet Food 150g (Saltwater Aquarium Supplies > Food > Dry > Pellets > Saltwater > Small Sized ) so I started feeding the tang these. I noticed that my hermit and emerald crabs love it, so I guess I got excited and started feeding a bit too much (in my opinion) of these pellets. Ok, everything was fine, water clear, etc. I went to the LFS to get me some cleaner shrimp and a sand sifting goby three days ago, when I got back home, my water had turned green!!! in a mater of hours!!! So you can see how confusing this is...why on earth would the water turn green? and what can I do to fix this problem?.
One more thing, I started using salt from a new bucket a few days before this happened. It's still the same brand IO. I'm trying to pin point the culprit. Could've been the pellets, too much light/lunar, the new salt.
I did a partial water change and changed the carbon on my filter, I have two cartridges in there now..so far no difference. I have a 46 Gal. tank and did a 7 gal. water change that night the water turned green. I'm not sure how much more I should change.
My fish are fine, there's not sign of stress, they are happy and eat.
If a UAV is necessary, I need you please tell me HOW to use it. Will I need special equipment? All I have is HOT power filter and remora skimmer. Three powerheads. That's it. All the UAVs I've seen look like sticks that do nothing...I have no clue what I need to use them and/or how to use them. If the UAV is the only what that is.
Anyway, thank you for taking the time to read this long post. Peace.
