View Full Version : 10 gallon marine experiment
I had a 10 gallon brackish tank, but I used (gasp) aquarium gravel. So, I bought another 10 gallon tank, including a filter, heater, hood, etc.
I moved my animals (mostly crabs of varying species) over to the NEW 10 gallon tank, and have it setup now with (sigh of relief) sand.
Now I have a spare 10 gallon tank, filter, heater, light hood, and light. I just set it up, 1.022 specific gravity and 2" of sand on the bottom.
I'm going to simply let it sit. I don't think there is enough bacteria on the filter element to properly cycle, so is there something that I could put in the experiment tank to cycle it? I'd like to get algae to grow, and hopefully little pods to eat the algae, then I may consider setting it up as a micro reef.
Perhaps I may go to the ocean and get a jar full of ocean unfiltered water and pour it in at a later time, just to see what will grow.
Ideas or thoughts? I'm just going to leave it alone, nothing will go in except a small critter/fish to get it cycling, then that would be moved to my brackish tank (thinking about a goby for this).

Adding live rock will usually start a fishless cycle, with the die off from the hitchikers witch didn't take shipping and/or transport (from LFS to your home) to well supplying the ammonia, and this is probably the most commonly used method of cycling a marine tank (though some will throw in damsels to help out - don't do that!).

Most people would want to not have algae grow :). Algae WILL grow, and pods will probably do the same with no fish in the tank, but you will need to introduce the pods, which will probably follow the same course as algae if there are no predators in the tank. Algae growing and pods reproducing isn't really much to start with and get a feel for the hobby before deciding to go to reef or not, personally, I think I would start out more along the lines of getting a fish in the tank before making the decision.

Cycling with fish is never a good idea, the ammonia involved with the cycling process literally burns away at the fishes gills, not cool if your the fish ;). And I'm guessing your planning on using a brackish fish, and putting it in the saltwater tank short term to cycle the tank? Not really a good idea to put a fish in a salinity it doesn't naturally come from, a brackish fish would be better suited for this plan than a SW, but regardless, you shouldn't be using a fish to cycle the tank anyway.
Might want to read this sticky on Cycling Methods & Procedures (http://www.aquariacentral.com/forums/showthread.php?t=91273).
And the rest of the stickys throughout the marine section would be worth reading through, as well as the marine articles in our article corner.

Well, as I mentioned, I'm using a used filter, so odds are it will cycle itself.
As for fish, the goby I would use is one that's used in brackish and marine, I believe a Violet goby. My brackish tank is actually 1.0175, so a marine fish would do fine in it. i actually have some "freshwater" ghost shrimp that are living, and indeed, growing, quite well. I believe they are actually marine shrimp that my LFS sells as freshwater feeders (hence 90% of their shipments die when they get them).
I find biology amazing. Having little pods running around and eating bacteria would be an enjoyment for me. I may do live rock, but I don't know if I want anything living in the water just yet.
Algae and little pods would be the food source for the emerald crabs I'd like to get for it if I do do live rock. The algae for food, the pods for entertainment. :P The algae/pods really aren't related to doing a reef, directly. Maybe I'd do a reef if I got sick of a green/yellow tank sitting next to my bed all the time. I'd like to do a reef, but I don't know how successful I would be with a small reef. I don't know if I really want to take the plunge yet on that. Other than a test kit (PH, ammonia, nitrite, nitrate), hydrometer, heater, and filter, is there anything needed?
And, last Q, where can I get some little pods? :P

It would be a good idea to throw in alk., calcium and phosphate test kits as well, though they wouldn't be nessesary. If it were a normal tank I would add in a small powerhead for extra circulation (or a larger/more filters), but an algae grow op. isn't exactly a normal tank ;).
And actually now that I think of it, for what your planning, you wouldn't really need the tank to handle much of a bioload, so the filter would probably have all of the bacteria your would need.
You can get bottled pods from oceanpods.com and there's a few other places that sell them as well. Or you could just get them as hitchikers(from live rock etc.).

Thanks very much. I don't suppose hermit crabs, larger crabs, or larger shrimp will eat them? Maybe I could add a few to my brackish system... I'm going to see if I can get some from my LFS.

RE: Cycling with a fish. Why not toss a fish in, and pull the little thing out once the cycle starts? Easy cycle start, plus your fish doesn't experience ammonia.

Because your tank needs a constant source of ammonia. Thats why you use Live Rock, Pure Ammonia, or a fish(:silly:)

Ahh, I knew there was a missing piece of logic in there.
I'll try the fish method with some dead feeder fish (I ironically had a cycle happen due to bad food again, I moved my crawfish and it's feeders before it happened, but there's a bunch of dead and rotting blood worms in the tank now). One of the feeder fish hid from me when I was moving them over, so now it's dead on the filter, I'll toss it in the other tank to get it started.

One of the main reasons we dont advocate adding a fish to cycle an aquarium is because its cruel to the fish and its easy for the fish to get ammonia poisoning..
A great ammonia source is either pure ammonia or a raw shrimp/prawn..

I've got some dead fish on hand that I just tossed in. They were supposed to be food for my crabs, but they died pre-maturely, due to some kind of disease I think.

Large crabs and shrimp probably wouldn't give pods any trouble, but hermits I'm not sure.

Okay. Now I have a conundrum, I have a big crab in my brack setup that's not reef safe, and small hermits that are. lol I think I'll keep watching the tank for a while, and once it's cycled and I have algae, I'll decide what to do.

In order to retain the existing bacteria, you have to slowly raise the specific gravity. A rapid increase would kill them off in huge numbers.

Yeah, right now I'm starting a-fresh. I don't think the old bacteria survived anyway, so it's getting a new cycle. Using dead fish, as they were on hand.

Tank is cycled (used media from my brackish tank and slowly increased the salinity level). Got a blue legged hermit living in it with some 2 lbs of (for now decorative) liverock. Nothing living on the liverock other than the hermit. :(

You may want to go to the local fish shop and pick up some cheato algae. Most times if they pull it from the sump it will have hitchikers like pods and feather dusters. Maybe even a bristle worm or snail.
I started my salt tank rather oddly. But it was a start, and I enjoyed following the little trails in the sand/mud on the bottom of my tank, just seeing some action. I could see pods, and other things.
Just getting some pink coraline on my glass was exciting :)
After awhile, maybe get some nassarius snails
Cool idea! I was told to get out of the house today, so maybe I should do just that (I've been sick for a week now).

Some of my new live rock has already started sprouting new growth, there appears to be a baby aiptasia even! I'm so happy! Er, not. Looks like a few peppermint shrimp will be coming home with me tomorrow. :(
There also appears to be a baby starfish as well, it has narrowly avoided being spotted by my red legged hermit, if the little hermit would even be interested in it.
I went to pick up some blue legged hermits today, just to find that someone came in and bought the entire shipment bag that the LFS got in. ****.
I did end up bringing home a red scooter blenny. It'll be fed on algae chips and shrimp pellets until I have more substantial growth of algae in the tank. Also added a small amount of seaweed for the emerald crab I got the other day to hide in. I've stocked out my nano with about 5 lbs of liverock, 4 hermit crabs, a Mitrax crab, and a single, solitary fish. 5 more lbs of liverock will be going in after my trip this weekend, unless I misdiagnosed my aiptasia, it may yet be something beneficial. :p I'd like to end up with 12-15 lbs of liverock, but I also have to buy additional testing equipment (calcium and iodine levels, for starters).
Tank ammonia is 0. Nitrites are 0. Nitrates are ~18ppm, 3 days post water change. :) Oddly enough, with more live rock, I could add in a small goby and call this tank fully stocked. :D
