Hornwort = Brown

[FtwayneFish]

mine only does it on the bottom of the bunch, like its not getting enough light. but again you can let it grow and trim and throw. thats what i do. i mean its a tad brown and it grow well at the surface so i just rotate lol. and i put the old peices in my other tanks sometimes and they seem to come back.

it was ick clear a little brown bottle i think i finished it i also used the jungle brand the fizz tabs...so they dont like any salt....what should i do

Almost all Jungle products contain salt. There is no need to add salt.

I heard that sometimes if they get too much light, their tips will turn reddish brown, but that does not mean that they are dying - it should turn to green - only tips stay red - so I'm carefully monitoring it, even taking pictures to compare from day to day... waiting to see what happens.

Yep. Most red-leaved plants like more lighting than green ones.

In future if treating sick fish, they should be removed from aquarium and placed in separate container and treated there so you don't contaminate your tank with medicine or salt.

Not all diseases require isolation. Any mass outbreaks or in some cases, contagious diseases should be dealt with immediately in the main tank. Otheriwse, your efforts to contain the disease are simply pointless.
