Discus egg fungus prevention

[Bijack]

Noticed some white fuzz on my Discus eggs last spawn. Water params are good, 0 ammonia, 0 nitrite, 5 nitrate. Tank is 75 gallons, temp at 84F, sponge filter running. Anyone got tips to stop the fungus next time?

Methylene blue works wonders for egg fungus. Dose it at 1 drop per gallon right after spawning. Also, make sure your pair is in a bare bottom tank, easier to clean. What's your water change routine?

[Bijack]

Thanks, Duppy. I do 30% changes every other day. Gonna try the methylene blue next spawn.

Agree with Duppy on methylene blue. Also, increase aeration near the eggs. Fungus thrives in low oxygen spots. I use an air stone angled toward the eggs. How old is your pair?

My pair's about 2 years old. They're in a 55 gallon with sand substrate, lots of driftwood. Spawn every 3 weeks but lose half to fungus. Gonna try the blue stuff, sounds legit.

Yo, same issue here. Tried methylene blue last spawn, eggs stayed clean. Also, keep the lights low, fungus hates that. My tank's got Java ferns, no CO2, temp at 86F.

Lights low? That's a new one. My tank's got LEDS on for 8 hours, maybe that's the issue. Also, what's your pH? Mine's at 6.8, soft water.

Yep, low light helps. My pH is 6.5, RO water with a pinch of minerals. Less light, less algae, less fungus.

Man, this thread's gold. My pair's in a 40 breeder, bare bottom, temp at 85F. Gonna grab some methylene blue tomorrow. How long do you leave the blue in?

Leave it till the eggs hatch or go bad. Usually 2-3 days. Also, siphon out any unfertilized eggs ASAP, they're fungus magnets.
