coral catsharks plan.

All you need for sharks is to focus on mechanical filtration and biological. A good canister, pt skimmer and plenty of surface area for bacteria will do. No need for a sump at all if you don't want/need the extra water volume.

how sensitive are sharks to nitrates? i assume with your advise i could use my xp4 canister, my asm g3 skimmer(need a sump for this, but will use my 40g), and bio-balls because i have about 100g worth sitting around. atleast on my 180 till i upgrade.

Depends on who you ask. I've seen them thrive and breeding in nitrates well into the hundreds.

I agree, but obviously you want to keep it as low as possible. No need to stress however if you have some nitrates in your tank.

does anybody have possible sources for these sharks? someone suggested tropicorium to me.
