Hi everyone! Wow, an introductions thread, I feel so welcomed already
I am really happy to be part of a forum with others with the same addiction

I've been into the hobby for quite some time now, but it's only in these past 2 years that I began to get my arms really wet from setting up (freshwater) tank after tank for myself and family/friends.
I've recently mustered up the courage to care for some Discus fish and I can't believe I've waited this long to have some. They bring me so much joy. I know I have overstocked my 55gal with 7 Discus' and 100 rummynose tetras that school beautifully

so I have been doing daily water changes of about 20-30%
That being said, I'd like to ask your experiences in doubling-up on filtration. I currently have an Eheim 2217 set-up on this and I'm considering on adding 2 airpowered filters in the corners, but still undecided on corner box or sponge, tho I do see a lot of set-ups using sponge filters with their Discus fish. I am also considering those double sponges that attach to the glass.
If you look at the pic attached, you'll see that I also have a bubble curtain in the back there for water movement, but I'm considering to remove it if I do setup the corner filters so I could conveniently use the airlines already there. But I could always get another air pump, and split the airlines to share so I could keep the curtain. Will that be too much movement for the Discus' tho? Hmm
Anyways, I'd like to hear your suggestions before I get anything more for this tank. Time for me to look for a Discus thread in here now
