Dosing Salt for Algae Removal

[ohhfishhh1]

Hello! I'm having some trouble getting rid of some stubborn algae in a few artificial tanks. They way my job is setup tank are cleaned every 2-3 weeks and in some of them once the algae starts it's impossible to get rid of. Since salt isn't good for plants, do you think that adding a small dose of aquarium salt would help stop or slow the growth? The tanks are spread out across the county so daily water changes are out of the question, and I'm not comfortable adding chemicals to reduce algae growth. Let me know if this crazy idea of mine seems doable or if it sounds like a bad idea.

I’d be cautious with aquarium salt for this. It may slow some algae, but it’s not a reliable long-term solution and can build up between water changes, potentially stressing fish and damaging salt-sensitive plants.

Since you’re already avoiding chemicals, I’d focus on reducing excess light, improving circulation and filtration, and manually removing algae during your regular cleanings. A properly sized UV clarifier can also help with suspended algae and reduce recurring green water without adding chemicals. For tanks that are spread out, that may be a much more practical long-term solution than trying to maintain a specific salt concentration.
