Filtration for shark tank. Yes, a shark tank.

I'm starting up a 180 gallon tank for one marbled cat shark. I have a 75 gallon tank that I will be making into my sump. I have a 1800 gph sicce pump and a 250 gallon reef octopus skimmer. I am worried about properly filtering my tank. I was planning on having a few live rock in the tank for my sharky to hide in and have the rest as open sand. I was also planning on having a load of live rick in my sump to act as my bio filtration but was also considering a trickle filter with bio balls. Since I am designing my own sump I have the ability to do either. Or maybe both? I was also planning on putting a carbon bag in there. Let me know what you guys think and any input helps. Thanks

I think your tank is way too small. I think you'll get bored with a shark. I think you have a lot of reading to do. Good luck.

Trust me my friend I have done some reading. And I wouldn't say whether or not someone else could get bored. My interest level isn't dependant on how active the species is rather than my love for caring for and keeping these exotic beauties. I am simplyg concerned whether or not I have enough filtration for this species in this tank.

Live rock in the sump can't hurt anything.

I'm sure you have done some reading and that's great. But, your planned tank size and plan to throw a bag of carbon in the sump lead me to believe that you have more to do. I'm not trying to be flippant, but people with those red flags, low post counts, and plans to keep sharks make me suspicious and I hope that person will proceed slowly.

I shouldn't assume you'll become bored with a shark. But, I would eventually become bored with a single species tank, and also frustrated with being unable to find a suitable home for that shark once I wanted other things. Just something to think about.

I appreciate that, "throw" was a figure of speach. And most of my hobby has been locally grown. I am just starting to branch out to forums because I can't find the answers I am looking for locally. Thanks for your input.

Agreed with hippiesmell. Carbon, bioballs and liverock wont reduce nitrates. Look into various forms of nitrate-reducing filteration on the forums

I have heard of people having success with matrix, anybody ever used it?

A 180 is fine for a marbled cat shark, I use to have one myself in a 180 along with a 3ft snake eel and other fish.

However, a trickle filter with bio balls?? This isnít 1990. Iíd suggest a large sump with live rock and a big skinner along with a sulphuric biodenitrator.

Also, post count means absolutely nothing... Iíve been in this hobby over 19 years and even active on local clubs. My current local club is slow so now Iím here on a national forum. So donít judge by post count....

You're in the minority for thinking a 180 is large enough for a three foot long shark.

Also, post counts do matter when you know nothing about the poster. You have to assume they're inexperienced until proven otherwise. I've seen a lot of new people come through here, many of whom want sharks.

I agree with the need for nitrate reduction. Bio balls may work in combination of live rock. Carbon will not. Personally I would do a refugium in the sump, where you harvest chateo in conjunction with LR. You could also do a nitrate reactor.

A shark in an aquarium is a depressing thought

Iffy size tank for that shark. Best recommendation would be swing over to the FOWLR section and see what resident shark expert alprazo thinks. @ktownhero alprazo's tank would change your mind in that matter.

As for filtration, trickle filter is a few decades out of style. If that is what your reading has led you to, time to update your research. Sand or diatom filter would clean the water the of big particles, skimmer, and some bio-media for denitration. Dedicate a sump section for siporax or something like that.

Personally, I'd do:

filter floss / sock , properly sized skimmer, a fluidized sand filter (cheaper and better filtration than matrix and other bio rings, especially for that size/bioload) and a refugium or algae scrubber for nitrate and phosphate control.
