Subject: Re: Identifying growth on fin by oldsplasher on 23/8/2020 9:43:52 I have used nitra-zorb pads before, in my tanks, to help reduce nitrate levels. They do seem to work, and can be re-charged by soaking in aquarium-salt water (instructions are usually given on the packet). They eventually have to be replaced with new ones, though. I used to get mine off Ebay, although I'm not using them at the moment. |
