I just recently upgraded from a 120g to a 180g. I transferred all my fish and same filter. I was wondering if you guys think this is enough filtration with my current stock.

Filtration & setup:
2x fullsize sponge filters
2x Eheim 2217
Cora life Uv sterilizer
Hydor korilla wave maker
Barebottom tank to keep things clean

Stock:
1x 12" arowana
10x 4-8" clown loaches
2x 5-7" indo datnoids
1x 10" flagtail

The above stock was in my 120g for a year already with no issues. I do weekly 20-30% W/C and feed every other day or every two days. Strictly pellets and occasional bloodworms.

I will also throw next week in my 180g
3x 4" stripped silver dollars
1x 6" tigrinus

Let me know what you guys think. Your opinion is greatly appreciated

Agreed, I'd already be doing like 80% w/c weekly with that stock. As that tig and the rest grow you're probably going to run into biological issues as things stand. Fully grown, all those fish would need a tank slightly bigger with a sump or something similar imo.

Space is limited so biggest i can go is 180G.

I thought maybe the two sponge filters will help a lot. I dont mind doing extra water changes, i got a powerful pump and just fill it up w/ garden hose

I personally think you should be fine. Throw in another large sponge filter if you are concerned about BIO capacity. Routinely check your water parameters and adjust the % of WC change if need be. If everything was is order from the way you were doing things in the 120, then you should be ok with the 180. Another 60 gallons is no big deal IMO.
 
Why add an additional ugly sponge filter? Just max out the existing canisters with biological media.You will eventually need to upgrade those canisters though as 400 gph is a little over 2x turnover rate which will be way too low. You will need to be around 800-1000 gph with that stock with weekly 50-70% WC's

x2 I agree....add a sump and scrap the sponge filters. With a combo of a sump, canisters, and the the wavemaker you should have decent filtration.
