Don't have a phosphate pad, don't think I can fit on in my filter anyway, it's a Internal Eheim 2010.
Though planning to upgrade to a canister but havn't found one yet, limited budget.
Did a 25% water change yesterday and today also, and all the blue hygrophila plants I've taken out, so most of the hair algae is gone.
I'm thinking if I add a new java fern, if new hair algae starts to grow the SAEs should eat them before they grow further.
More inputs appreciated thanks.
