Can several people please tell me. What are the "general" toxic levels, for a tank with fish and invertebrates? As well as "general" normal levels. Again I am not looking for ideal just trying to get an overall average. Nirtite, Nitrate, copper, Ph..... etc. etc. etc.
Thanks in advance for all your help.................
Tank has:
Sails
Crabs
Stars
clowns
shrimp
blennies

Ammonia 0
Nitrite 0
Nitrate As low as you can get it. Inverts and corals much more sensitive to it
pH 8.2-8.4
Copper 0.000000 if inverts are present.
"toxic" levels vary. You can't really ask "what is toxic". Fish and inverts will respond differenty. Don't shoot for "below toxic", aim for pristine water conditions.

It depends also on whether they had time to adapt to the levels or were suddenly dropped in, my pet store had cleaner shrimp in 150+ nitrates just fine but anything new added died.

Nope not dropped in. They are in on going levels. Just where I live there is only one fish store within a 250 miles radius and they don't stock much for salt water fish supplies. Oh! we do have a Wal Mart .....lol So, that being said. I have either UPS ground or UPS red label for what ever I would required. Not so much for salt but say different types of buffers etc. etc. Everything right now is fine but, if something should shall we say blow up! It would be nice to know where lethal levels really are. Ya, I understand there are lots and lots of variables. Thats why I just wanted some averages......... Just other peoples "OH ?#*% levels. I have read in other threads/boards about (my tank overnight did this or overnight my tank did that) etc. My ph went to or my nitrite went to that. I think you can see where I am headed now. Which brings me to another question. Any ideas what one should have on hand/stock for supplies for one like me who does not live in or near any larage cities for supplies.
Thanks for your help.................

IMO panick should set in with Ammonia at .5-.75 (something died), Nitrates at 40, Copper ANY and it is over for a reef, Ph < 7.7 or over 8.6,
Personnaly, if I have ammonia detected, I find out why. High trates >20, I do a water change to get it back to 10. Ph I buffer. Remember to always dose your tank slowly over time to get the paramters back. Only bad things happen fast!

What they said

On hand you may want amm. lok, salt premixing at all times, and some carbon. chemicals are only a last resort. You wouldmostly want to try to correct anything with you weekly water changes.

Honestly, unless you have a lot of hard corals, adding buffers and chemicals isn't neccessary. Keep some salt on hand to do routine water changes.
Ammonia should always be 0.0 Anything else get worried.
Nitrite should be non-existent.
Copper MUST be 0.0
Nitrates depend on your tank. I try to run 0.
pH will flucuate a little, by wide fluctuations can be a sign of "old" water or the need for more aeration.
