Re: need chemistry advice... ASAP

Okay here is the situation...

Not sure why but my tank has started cycling again.

I just tested everything...and nearly choked when the test results came out.

Everything has been looking great EXCEPT my toadstool. The toadstool has been opening up, but not for long and closes up more than I have ever seen when lights go out. I had a few people tell me he was just growing.... My Picasso looks normal.... no gasping for breath, he is eating and swimming normal etc.

Snails are super active, shrimp is doing his usual...

But.... here are the results.
The good..
Temp: 80.5
Sal: 1.0255
PH: 8.4 (api)
Alk: 10 (api)
Calcium: 480 (api)

The bad..
Nitrite: 0.1 (nutrafin)
Nitrate: 5 (nutrafin)
Phosphate: 0.5 (api)
Ammonia 2.4 (nutrafin)

Here is my dilemma... I have no premixed salt water at the moment. I have salt, but nothing mixed. I usually do, but I had decided to switch to NSW (natural sea water) and I am getting it delivered on Monday morning. So I didn't make up a new batch when I ran out.

So would you mix up a batch right away and do a 30% water change? or.... Mix up a batch let it sit for 24 hours then do a 30% change? Or lastly wait until the NSW comes monday morning and do the 30% change then

Is 30% enough?
