so i will be upgrading either to a 180g or 240g. not too sure yet.
I'm going to try a Predator tank. lionfish, eels, And a bamboo shark and maybe a stingray..my Q?
is there a big difference in the kind of setup i would need.. as in is it better to run a wet/dry kind of a system w/o refugium or actually do a refugium... I was told by my local fish store that it would be better to use bio balls with the predator tank because of the fact that I would be having to battle more of the ammonia and nitrite rather than nitrate if I were to try and house a bamboo shark and some stingray. which of course it didn't really make sense to me reason why Im posting this question.lol
ill be designing my sump 65"L 24"H 24"W i want to do a big refugium
in order for me to fit all the rock from my 125g all 142.65 lbs of it.
.my thought was that i may use the rock if i wanted to go back to reef.lol.
dont feel like buying whole new rock for the aquascape..lol

dose it make sense.
or am i dumb..

thanks for any answers...

The people at your LFS are on something. Your thoughts are correct once the tank fully cycles you won't be fighting ammonia and nitrites. You be fighting nitrates and phosphates.

Great idea on reusing rock and keeping it cultured. Better then spending a pretty penny buying new rock and having to cure it. Plus moving it will create more biodiversity and prevent old tank syndrome. And seed the new tank drastically shortening cycling time a small culture of the old tanks sand would also help seed the new sand bed.

Word of advice, put the rock in the fuge in a extremely high flow area, use a power head if needed or you'll get ditirious build up. which will be nothing but a headache to clean having to move that much rock.

Bio balls are nitrate factory's don't use those, wet dry with your heavy bio load would in my opinion be a ditirious trap and be more cleaning. If you have porous live rock and that combined with sand have exponentially more surface area then both bio balls and wet/dry combined. But that's aerobic bacteria. Only anaerobic bacteria consume nitrates.

What are you trying to accomplish with the sump? A refugium is a refute for pods and micro organism to reproduce in a safe place and not be eatin like the main tank. But I'm assuming that you wont have fish that eat what I just mentioned.

The only other option I can think of is a place to get the ditirious to settle for easy cleaning and remove nitrates and phosphates by both mechanical and biological means. So a way over sized protein skimmer and phosban reactor are necessary. Those will solve the dissolved organics. But you would still need to get as much ditirious out of the system as possible. If you could make a place for as much of that to settle that's easy to clean and get to. For biological I would say cheato for macro algae and nutrient export and possibly a DSB. For anaerobic bacteria to grow. Preferably this would be after the return pump where I would think the lowest flow would be. That would create the best anaerobic conditions and give maximum exposure time. But I personally don't like that the anaerobic bacteria can be exposed to something and die off causing the tank to crash. Also takes quite a bit of time to culture anaerobic bacteria. I think effective skimming and reactors would do a better job then a DSB along with not having to worry about bacteria die off causing a crash and killing everything. Cheato is never a bad idea if you prune and rotate for light exposure.

You can't get around water changes or siphoning. So keep it simple (eg all siphoning done in one concentrated area) and easy.

I'm sure you already know all this but thought I would throw my .02 cents in. Good luck with the set up!

Also if your looking at a predator tank look into a bumble bee grouper. My LFS has one and if I had to describe in a short statement. I think "one man wrecking crew" would be best fitting. It follows people from one end the tank to the other. During feeding it's a beast. Takes the workers at the store 15-20 min to get food to the stingrays in the same tank.

If I make it there today I'll take a pic and post it if you want.

Great writing.
+1 on the powerhead to move water across the refugium.
And i was thinking about doing that. but am leaning more towards a wet/dry system now
Still trying to figure out a way to include my LR from my 125 as a biological source:..lol
But ur right about the whole maintenance of it in a refugium..i will be looking a the right protein skimmer size .. And everything else..thanks. .

Wet/Dry isn't bad, Im sure there are many members that successfully use one it'll just take away quite a bit of space away from putting live rock in. Unless you broke it up into rubble and used that for the wet/dry instead of bio balls which I just thought about. I think that would work well and be a better alternative to bio balls. Only downside is that you wouldn't be able to use the live rock again to set up another tank. Or rumble some rock, put "smaller" pieces else where and sell whatever is left that you absolutely can't fit in the system. Throwing out ideas lol there is no right or wrong answer.
