Reddit Discussions
On Reddit and spa care forums, hot tub owners often discuss AquaDoc Spa Defoamer as a useful product for addressing surface foam between deeper cleanings or after frequent use. Users typically recommend keeping a defoamer available for quick, convenient foam control.
What if this doesn’t remove the foam from my spa water?
Most users find the defoamer effective when foam is related to oils or residues in the water. However, persistent foam may indicate underlying buildup or water imbalance. If foam continues, using a clarifier alongside the defoamer can help address contaminants that cause the issue. Our support team can also help identify the right AquaDoc product for your spa’s needs.
How can I prevent foam so I don’t have to use this product frequently?
Foam is often caused by oils, lotions, detergents, or other contaminants in the water. To help minimize foam:
- Avoid using fabric softener on bathing suits.
- Rinse off lotions, oils, or cosmetics before entering the hot tub.
- Keep hair products out of the water when possible.
- Regularly use a water clarifier and defoamer as part of weekly spa maintenance.
