Welcom to Tropical Fish Keeping forum.:wave:

Hairgrass is not always easy to grow. It needs good light, and nutrients to balance. You can try, and if it makes it, fine, but if not, look for an alternative. Most peole find it only manages well with high light and CO2.

May I ask what the salt is for? This is detrimental to plants, some more than others, but even more importantly it is harmful to many fish. You can read more here:

i was told the salt would help when i set up a new tank....thanks for info, any idea want plants might survive or should i just stick with artifical

i wish i had read that about the salt before i put it in, looks like im gonna do a complete water change to be safe

I am still new to this but I was told to get Java Fern, Anubias, and water sprite for a freshwater tank and it has work out so far like a day but they are really hardy plants from what i read in the profiles about them

Capra's suggestions are good, and they will manage in less light (the Water Sprite is floating, the other two attach to wood or rock, have a read of the profiles, click the shaded names in the last post).

Other possibiles are pygmyu chain sword, chain sword, dwarf sword, any of the cryptocoryne species (check our profiles).

Yes, i wold get the salt out, it has no benefits. If you get enough plants, you will be able to add your first fish with no cycling issues.

i just planted a argentine sword and an anubia. what should i add for nutrients for them.

Pretty sand and healthy looking plants. If that is a Anubias you better attach it to the wood or a rock with some fishing line, its not suppose to be burried. I have also tried Dwarf Hairgrass with poor results, its tough.

i will try that today, didnt know it wasnt supposed to be buried. it has some really healthy roots on it.

The roots can be buried, but not the rhizome.. the thick tube the roots and leaves all attach to. That needs to be above the substrate. If you don't want to attach it to wood or a large rock, I had luck tying my anubias rhizome to just a small pebble/rock and you can bury the rock a little.. the plants growth should eventually cover the little rock.

As far as fertilizer, for swords you may want to go out and get some quality root tabs and place one below it's roots. You can also add a liquid comprehensive fertilizer, many of us use Seachem Flourish comprehensive and that is a simple, balanced way to get the necessary nutrients in the water column for plants like the anubias.

I would suggest adding a floating plant like water sprite, you can also float pennywort. Some true floating plants like amazon frogbit and dwarf water lettuce are also great if you can find them. If you can't locate them locally you can usually get some for very cheap or free (just pay shipping) from someone either on this forum or on another online forum.
