Thank'sin advance!

I've been squeezing the sponge out daily in a separate dry bucket, then filtering the rots out of the sponge water, and using the filtered rots for my larvae. The sponge filter goes back into the culture. These rots are not harmed by living in the sponge, and the culture in the bucket, outside of the sponge, is full of rots, too. I remove rots from the water every day, too.![]()
This find would make me feel much better about introducing a sponge filter earlier into the larval raising phase as well - had always thought that a sponge filter would filter out all the rots and leave little for larvae!

Mine was cheaper than this one....

Hey there, I am interested in finding out about the heater too. What do you have this set to and how big a heater is it?
This would help my current rot production I think... Especially as I will not need to change every day.
