Tank help

Hello,

I am relatively new to axie ownership. My little axie Buffy is doing great, eating, she looks healthy and is active BUT my tank water is so murky and I can't figure out how to clear it up! I had several plants in there but took them out because I thought they were causing it but it didnt change anything. I do regular water changes and try to clean out any debris that I see. I've tried a tank water clearing substance but it made no difference. Any tips or advice to fix this??
