Need to treat a 75g SA cichlid tank for ich yesterday. Can't salt due to cories. Ich-X seemed to have the best reviews until I saw not to use it with Prime or Stressguard, which is all I use. Have temp raised to 87 and started Paraguard, but not impressed by the reviews of not working on ich or taking 4+ weeks. Don't want to mess with Cupramine. Only have Sulfaplex and Paraguard on hand. Should I try Polyguard? Something else? Any experience appreciated.
