Water Quality

[Dopey]

I was wondering if anyone would know why my water is turning bright green daily...?

[mr_alberta]

Phyto bloom is my guess.

Do a couple of water changes. Also, you might have to "black out" your tank if the problem persists.

[Dopey]

It does it with in a few hours of the water change.... how long would i have to do a black out for? There's a few things that need some light

Thanks Lisa

Do you use carbon? It could also be a result of high phosphates, do you use RO water or tap water?

Typically this type of thing gets worse with water changes, especially tap water.

[Chad]

yes, cuz your just adding more phosphates.. Its important to test your source water for phosphates.

Grab a test kit

If you can borrow a UV sterilizer, that will kill off the phyto within a day or two.
In the future, investing in a good RO/DI unit to filter your tap water will help alot.

I've been getting RO water from the grocery store( I know its not the best but its all that I can afford )

Theres Chemipure in the tank (only carbon source)

This is how the water looks during a change.



Lights Off.



Lights on.



After one day it got worse



Is there any way to help this problem with out a uv sterilizer?
If there isn't where would be a good place to buy one?
