i think from 5-7 or something like that.
I m not sure on the discus buffer, But all i know is i had a no hatch rate, to me not using as much DB and then magically i get babies,
Then i changed water and put some DB in it and got one wiggler with the new batch.
As compared to with less DB where i got 6-10 wigglers,
Ive been trying to raise discus eggs for just under a year, With no luck, Thats including taking the eggs away from the egg eater. And trying to raise them on my own, caging, trying different things, These fish would lay every week.
Ive tried everything except RO and of course bottle water.
I would like to rule out everything i am doing before i go spend 100-500 dollars on a RO unit tho, which i have been contimplating.
My final guess is DB, but would like some expert opinions.
