Carbon and RO unit

Written by allan on . Posted in Aquarium Tank, Water and Filtration

I just wanted to know if it is safe to use Carbon filter For Discus fish. I was also interested in getting a RO unit what doyou think? I have a 46 Bow front Tank with 7 Discus.

How many water changes shall I do a week? Also vacuum gravel?


Personally I do not like to use carbon filter, especially for discus. Many trace elements and minerals required by discus fish will be disappeared.

We use water direct from pipe. What we need to do is to neutralize the Chlorine with Chlorine conditioner.

If it is a show tank with complete set ups, you need to change 20 to 50% of water a week.
The important thing is that: do not overfeed your fish.
