Hello Alex. I keep extremely clean tanks with good filtration, so I don't worry about quarantining anything. But, for whatever reasons, not everyone removes and replaces as much tank water as I do. So, I've never worried about separating plant or fish for a period before it goes into my tank. For plants, I just rinse them in warm water and remove any leaves that don't appear healthy. Then, they go into the tank. Aquarium plants are tropical, so they're used to long hours of daylight. I recommend keeping the lights on for at least 10 hours a day. Up to 14 hours is the maximum. If you keep low to medium light plants, you won't need to fertilize. Just feed your fish a variety of foods and they'll do the job of fertilizing.When obtaining new live plants for an established aquarium, do you quarantine them? If so, under what conditions. Temperature? Any treatments? Salt (if so, what dose)? How long? Thanks.
Not sure if your in the US, but if you are, BucePlant.com have really nice tissue cultures and amazing plants. The plants aren't guaranteed to have no pests but the tissue cultures are.Wherever possible I buy in vitro (tissue cultured) plants which should guarantee no pesticides or pests. Especially important if you keep shrimp.
