OK...yesterday I put the salt in my tank for the first time and today when I tested with a hydrometer it came out with 1.025.... To my understanding that is a little high.. How do I correct this? Will it it simmer on its own or should I change some water and if I do how much? Also since it is tax free weekend Wal-mart is a no-go :doh: will it be ok to let a goldfish die in the tank to do the tank break in?
 
yeah. def. take the goldfish out...put a piece of raw shrimp in there for a few days--it'll cause enough cycle for you
 
The goldfish arent in there yet, but we havem and I dont want to go sit in walmart line for 3 hours for shrimp :( is there a reason why the goldfish wont work?
its 115gallon with live rock atm will eventually be reef tank with fish.
 
It's very inhumane to the goldfish. Please don't do that.

As mentioned, let live rock do the cycling for you - no need to torture any fish to get the tank cycled.

I think he mean he hated to wait for 3 hrs. in line to buy a shrimp @ wally's world....don't know, but that's what it sounded like
 
If he already hates that wait - his tank won't be progressing too much...

Easy guys,

You don't know if you don't ask. Eric was right, I don't wanna wait the 3+hrs standing in line at wal-mart for some frozen shrimp. If needed I can wait till late late tonight to get shrimp sorry for asking.

What standing in line at walmart has to do with my owning a tank ill never know.

I simply asked because we have goldfish here already. Nobody told me to use a goldfish i simply asked if it was a suitable sub. I didn't think of it in the humane way, but that was why I asked, so you could politely help me know if it was good idea or not.

I was told to use a frozen shrimp to get the cycle going.
 
i hear some people keep their salinity on the lower side so If somethin happens to where they cant top it off it wont be too high....anyways mine is at 1.023.

you might want to look into a refrctometer too...hydrometers arent that accurate.
 
either way, you can use a dead raw shrimp or nothing at all. I prefer the dead shrimp, others prefer nother. Either way gets you to the same place.

For over 20 years I've kept mine at 1.023 and for the longest time it was "standard". Nowadays I see people trending to higher SG - 1.025-1.026 - which is OK I guess, but as was mentioned - if topoff is missed or whatnot, it's less forgiving and the SG can go too high.

IMO 1.023 is fine for the inverts that prefer it a bit higher, and less stressful for fish that seem to prefer it a bit lower.

FO I'd keep at 1.020.

I've seen stores keep it as low as 1.017 in a FO to discourage parasites - I don't do that, we keep all our systems around 1.023, occasionally the FO systems dip to 1.022.

If you keep your SG significantly higher than stores do, best to take a bit longer to acclimate. It's more time-consuming to acclimate to a higher SG from a lower one, than the reverse - you can drop SG in most creatures without too much worry (except for echinoderms or anything really sensitive to changes either way).

But back on topic - IMO let the live rock do its thing on its own. There's no need for a big ammonia spike, unless it occurs from uncured rock as it cures. If the rock is already cured, you may not see an ammonia or nitrite spike. As long as you've given sufficient time for the tank to settle out and keep an eye on the water quality, after 2 or 3 weeks you should be good to go for a cleanup crew if your water quality is what it needs to be.

Most salts used to reccomend a salinity of 1.0235 and this is what most of them usually mix up to give or take when you buy a package or bucket and mix it up into 50, 150 or 200 gallons of water.
I have kept FO systems as low as 1.014 and most all of the fish did extremely well. We used to run our FO systems that low at Fish Store and More about 5 years ago. A refractometer is going to be your best bet to reading salinty accurately. Someone was selling one for $20 on the forums here.

I have always just let the live rock cycle my tanks and if needed I just added some fish food to the system.

The ammonia burns the lungs of the fish and makes respiration much more difficult. Its about equivalent to someone locking you in a hot smoke filled room that took days to clear. You might live but your lungs would be permenantly damaged. The LR will do its job and once your ammonia and nitirite have tested at 0 for 2-3 weeks you can add fish. Best of luck and happy reefing.


Thanks dawg, thats all i needed to know :) I didnt realiz it killed the fish in that way. thanks to everyone for your help as well. Today I put more LR in my system, pics to come!
 
Here are some pictures of my setup with the new rock i got yesterday. Alot of the rock is like red.... I assume thats good stuff? Also should I go ahead and hook the skimmer up? I was told by the guy I bought my tank from to not hook it up for a couple weeks.
