I think the 316 would work fine as long as the outer surface isn't damaged. The ends of the tubes and any place where the "passive" surface is cut will rust unless treated.
Have you priced up the titanium/palladium tubing? I bet that is big dollar.
Since he is a BB Member he doesn't have access to the "for sale" section.
The forum rules do allow a one time single "getting out of hobby" sale thread in the general section.
I like to hand tighten and then wrench it down a 1/4 turn. Not everyone's "hand tight" is the same. Since these four bulk heads are up high there will be little water pressure on them. Just remember, anything past tight, is broke.
Nice job on drilling the holes. Just to make sure you know, the bulkheads work better if turned around so the nut and threads are on the outside of the tank.
Welcome! Something to remember about a foxface is that they are poisonous and can kill other fish by accidental stabs. I lost a purple tang to one during feeding time.
I would put the box up high against the trim frame to ensure the water level is not seen when viewing the tank. I would drill the return line about an inch below the water. You can use elbows or lock-line fittings to direct flow.
It's a bigger fish so offer it some larger pieces of food maybe. Does it pick at nori if you rubber band it to a rock or put it in a feeding clip?
Mine was about 4" when I got it and now its about 12". We've had it for six years and the previous owner had it for three. Ours loves to be touched and rubbed too. I stopped doing as I was afraid it was messing up his slim coat. I used to put my hand in the tank and he would actually swim up and sit in my hand.
I think they would be safe once cleaned. I use oxalic acid at work to remove iron oxide stains from delicate things. Hydrochloric acid is stronger and would work too. Since the totes are probably not porous it should be easy to clean. After a few days soaking with acid I would rinse a few times. Adding baking soda to a rinse would remove any acid left.
Most SPS or Softies grow fast enough to make it worth it. LPS are very slow growers and not really worth the time/energy. If you are ordering large acans or brains and chopping them up and then letting them heal before selling then it can work but growing out mother LPS colonies to create a recurring profit is not worth it to me.
I merged your double posted threads since there were replies to each.
I agree with what Origami recommended. The moisture finds its way inside when sitting unused for an extended period of time and causes them to electrically fail.
Nasty! At least it was in the garage and not in your house.
For those members that don't know about his system and are probably wondering why he needs a ladder to get to the collection cup. It is a custom-built 8'x22" fiberglass semi-cone, powered by a ReeFlo hammerhead with custom needlewheel impeller. This thing holds 115 gallons of water. Here is an old picture and he has a larger collection cup on it now.
Sweet tank! Do you dose iodine at all?
Do you see any issues when you run carbon? When I had 50 E. quadricolors in my 120 they would all react negatively to carbon for days. Even when rinsed well I think there was still fines that got in the water and bothered them. I stopped running carbon and GFO because of that.
I have five 300w heaters on my tank. I let the temps drift depending on the season so I'm not paying too much on power to keep a higher temp than what is really needed. During winter it settles down to 76f from a summer high of 83.
YHsublime - You may want to think about using two heaters so if the one fails you don't lose all heating ability.
The sand bed does not have to be deep for a jaw fish. We have a 3" blue dot in a 16g and the sand is just over an inch. It dug out a spot under the rocks and just hides under it.
