Hello Everyone,

Does anyone know conclusively through experience a safe dosing of salt per gallon that doesn't negatively affect high order aquarium plants?

Please post,  best wishes!

Hello,

I think this is different for different types of plants.

I can say with some confidence that Jack Heller's cultivar of Hornwort (which doesn't drop its leaves and make a mess in the tank) can tolerate up to SG 1.004 (~5g/L).

I am told that some cultivars of Java Moss can tolerate 1.005 SG (6 g/L).

I have been keeping Pseudomugil cyanodorsali at 5g/L with hornwort and java moss with no issues. Sadly, even teh duckweek seems to survive.

I keep anacharis and java moss in my tanks set up for pupfish.  I'm not exactly sure of the salinity but I do add approx. 1/2 tsp per gallon and calcium carbonate and soda ash so it's very hard and the pH is around 8.2.  Doesn't seem to bother these plants, the snails are healthy and the fish love it.  Hope this helps.

Russel,

Helps immensely thank You!

I asked in another post about my lack of success with Ceratopteris thalictroides Water Sprite and people thought my use of salt killed it. I have Vesicularia dubyana Java Moss and Microsorium pteropus Java Fern that is thriving with my dose of added salt. 4 teaspoons per 10 gallons. Something unusual about my Java Fern is that it is not rooted or attached to anything. It grows free floating.

Duckweed is salt tolerant. It can survive brackish conditions.
