Please post, best wishes! Jim Langan, AKA Webmaster

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'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.

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.

I'm going to update this. I've been working on breeding Aphanius dispar lately and only found them to be productive when I got the salinity to around 17 ppm (approx. half of ocean salinity). My java moss doesn't seem to mind this salinity at all. I can't say the same for snails though.

I keep a species of blue-eyes (P. ivantosoffi) for years which does well at 1/2 seawater and I found that java moss would last for months, but would eventually die. Even then, it would just slowly go yellow and still provide the cover functions without any significant pollution.

But I have found that Susswasertang (Lomariopsis) stays green indefinitely, though it doesn't seem to grow. I prefer the tang in general over moss for a number of reasons even in my usual, soft water tanks.

It should ship easily and I would be happy to send you some, but it's the wrong time of year for me to do that. Hit me up in the Spring if you haven't found some.

It took a bit of time but it all dissolved. I think I'll try some true macro algae in the tanks and see if that works.
