I'd skip the feeder and just fast him. A healthy betta can handle a week without food. Less risk of ammonia spikes, and you won't come back to a cloudy tank.

Thanks, all. Gonna try the plant boost and Purigen. Didn't realize media spacing mattered—my sponges are jammed tight. Will adjust and report back.

Been struggling with my 75-gallon tank's bioload lately. Got 6 adult Discus, a school of 12 Cardinals, and 6 Corydoras. Running a Fluval FX6, weekly 50% water changes, but nitrates creep up to 40ppm by day 5. Anyone got tips to keep it stable without upping water changes?

Yep, they can eat frozen bloodworms, but don't make it a staple. Too much can mess with their digestion. I've got a 120g with 6 discus, same temp as yours, and I feed bloodworms once a week as a treat. Key is to thaw 'em properly in tank water first. Also, watch for any weird vibes after feeding ...

Could be allelopathy—softies release chemicals that bug SPS. Try carbon or extra skimming if you're mixed. Pure SPS tanks often run hotter alk.

8.5 dKH is solid, but SPS can be picky. What's your magnesium at? I've found keeping it around 1350-1400 helps. Also, how old are your bulbs? Radions lose intensity after 9-12 months. My Acros took off when I bumped alk to 9 and swapped bulbs.
