You can have a sump with low flow and I would rather have the added benefit of a large sump. It increases water volume, provides a place where you can house much more biological and mechanical filtration, can also have a refugium as well as a place to store additional filter material such as sponge filters for use in new setups.. Sumps for the win in my opinion.

It's been 27 years since having discus and of the many vids the is sound info and the welcome reminder I was looking for. Went through a power outage for a week and mine survived with no heat back up. When it occured they were about 4 -4.5 in size. With nothing to lose I used the airline and just blew into the tank manually every twenty minutes and they were coming up for air on THIER own as well. Could have let them but they survived so thought I'd throw in that experience as many would be freaking out.

I prefer real plants and also help absorb ammonia sparks and my Discus love it.

Useful

My fish get the peppering sometimes. If they're pissed off with me and they hide it is alot more evident. If they're out swimming and happy it is almost all gone
