How often you change the water and clean the interior?
You got this tank last Christmas, right?

A pinch, and i mean a pinch, once in am, once in pm.

Fresh water into the tank once the tank’s water is down ½” to 1” due to normal evaporation, as needed.

In 6-9 weeks the big job:

Change ALL the Fuval Fx4 filters plus add new Seachem Purigen and Carbon bags, rinse bio-foam filter and change 1/2 the water in the tank about every 6 or 9 weeks.

Very clear water my fish and fresh water snails are happy
