discus breeding tank water clarity

[Playful]

My breeding tank water keeps getting cloudy a few days after water changes. I've got a 75-gallon tank with six adult Discus, sand substrate, and a Fluval FX4 filter. Temp's at 84°F, pH 6.5, and I do 50% water changes every other day. Feeding beef heart mix twice daily. Any ideas why the water's not staying clear?

Cloudiness could be bacterial blooms from overfeeding. Beef heart's high in protein and can mess with your bio load if you're not careful. Cut back to once daily and see if it clears up. Also, check your filter media, might need a rinse in tank water.

I have same problem but smaller tank. 40 gallons, 4 Discus. Water cloudy after 2 days. Use sponge filter. Maybe need more filtration?

Yep, agree with Swiftsea. Beef heart's messy stuff. Try adding some purigen to your filter, it's a game changer for clarity.
