 Nitrates High
Need help guys and gals my nitrates are kinda high and I want to do a 5gal to 7gal water change tonight. I have a 29gal biocube an was wondering if i could clean the bio balls all at once since my tank has been up and running for 5 months an I never cleaned the bio balls. Will this be bad if I clean the bio balls all at once tonight? I guess what im asking is can i clean the bio balls an be fine with really no change in the tank? Thanks for any an all the help here guys an gals... |
