Looking for easy fertilizing routine
Just started a new tank after being out of the hobby for 10 years. I used to do EI back then but don't want to have to do 50% water changes weekly with this 75g tank. I'm planning for moderate lighting and co2. Just wondering what the consensus is on a simple and hopefully cheap fertilizing method I can use that won't require those massive water changes? And where to purchase? Substrate is inert fyi.
