Angelfish fry tank

[Drogon]

Hi again,
Just a quick question I’m sorry for keep posting different things as I said I’m new to this and I hear there are many experienced people on here so.
I have my fry free swimming and eating good they have been for around 7days.
I am doing 20% water changes daily and also removing any uneaten food regularly when i do the daily water changes do I need any conditioner ie aquasafe?
I put methelyne blue in on adding the unhatched eggs. Also do I need to keep the sponge filter on all the time?
TIA
Andy
