What is causing the foam? Foam by the wall is dark green
Seems to happen after backwash, but I just put in a lot of algicide

What is causing this green sludge foam in hot tub?
- Thread starter caliskier
- Start date
Alkyl (50% C14, 40% C12, 10% C16) Dimethyl Benzyl Ammonium Chloride is a quatanery algaecide and will foam. It is not recommended to use that type.
It looks like you need to slam your hot tub. The chlorine will get rid of the foam (and the algeacide too). It will probably eat up your FC until its mostly gone.

The green you see in it is probably alge being killed.

Also that type of algaecide will likely leave a black residue behind that feels like grease.

Read this for recommendations on how to maintain a hot tub/spa with chlorine. Now, that is based on a stand alone spa. Maintained properly like a pool extra "stuff" is generally not needed.
From the picture it appears to be in ground, but is that stand alone or connected to a pool? If it is connected to a pool you generally need to exchange water regularly so that the spa is maintained along with the pool.
We do not "shock" our pools, we follow the SLAM Process when there is a problem. For a small spa like that I would just drain/refill it and start over rather than SLAMing. If it is connected to the pool and you have this problem in both places than a SLAM is in order.
How much Pool School have you read? Start with these:
ABCs of Water Chemistry
Recommended Pool Chemicals
How to Chlorinate Your Pool
Thanks, I will look into these, it is a spa / pool combo, it is not clear from the picture.
I've only had green hot tub water after going away for a couple days and not adding bleach. The foam usually for me is the women's residual shampoo left in there hair also clothes detergent left over in the shorts
