Hi there and welcome.

While we wait for others to login, could you answer a few more questions to help them assess your situation?

1. What type of pleco is it? What size is it?
2. Can you describe the white spot? Is it just one? Is it raised? Fuzzy?
3. What ich medicine did you use?
4. Have you used any products in the tank other than the Aquaplus and ich medicine?
5. Have you rinsed or changed your filter media at any time in the past month?
6. When you do a waterchange do you clean the gravel? If so, how much do you clean per change?
