Well just got home and tested: after about 27hrs ammonia is at .25 but nitrites are close to 5ppm..so i am assuming this tank has not cycled..what next?..do I add bacteria again or just sit and wait?

I would agree that it isn't ready. What bacteria product did you use the first time?

I would wait until ammonia reads 0ppm, dose it back up to 1ppm and see what happens.

I used Fluval Biological. Should i also wait for nitrites to go to zero before dosing with ammonia again?

Never used that one. Looks like it should have worked better than it did. Adding more wouldn't hurt. Personally, I prefer Biospira which is locally available to me since Petco carries it.

No, there really is no reason to even test for nitrites other than a nice way to track the status of your cycle. Nitrites are very harmful to fish however the same receptors in a fish that absorb nitrite have a much higher affinity for chlorides. Basically, the salt in the saltwater blocks the fish from absorbing the nitrites and protects them. Nitrites are a big problem in freshwater, not so much in saltwater. The water chemistry in saltwater is also known to cause falsely high nitrite readings.

Would it be ok to buy Biospira and use that instead of the fluval?..didnt know if you could mix bacterias?..also would i be starting cycle all over again?..thanks for your info and help, I really appreciate it!!

It would be just fine to do that. You can mix nitrifying bacteria all you want. In fact, it is a good idea. Every tank is different and some strains of bacteria will do better in a tank than others. Eventually, the best strains for your particular tank will come to dominate even if isn't one that was added via a bottle.

This is where i am at almost 48hrs after dosing it to 2ppm..any ideas?

Wow. You have added a crazy amount of ammonia to this tank already. I would do as large a water change as possible and dump in a big bottle of Biospira.

I know some people will recommend dosing up to 2ppm ammonia almost daily but it isn't my preference. Nitrifying bacteria reproduce fairly slow when compared to most other bacteria. I recommend dosing up to 2ppm and then not dosing again until it is at or near 0ppm. This generates fewer nitrates and gives the bacteria time to grow.

When you say as large a water change as possible...its 110 gallons plus the sump..what are you thinking?..and then add biospira and test levels or just add ammonia?..could i get away without a water change and just play the waiting game?..just seeing my options..thanks again

You should be able to get away without a water change. I have around 140 gallons total water volume and the largest change I can easily do is 35 gallons and I can push it to 50g if I have to. I know when I started it was tough to do a 15g change. I dont think your high nitrates will cause too much of a problem yet but you will want to bring those way down prior to adding fish.

Setting up this in my garage was a huge quality of life improvement for me. But yeah, this is a little off topic.

That looks awesome!!!..I would love to build something like that, but unfortunately the winters here are sometimes brutally cold and my garage gets down into the 30's sometimes...hmmmm, i wonder if i could make in my backroom..

I'm in a much warmer climate so if it is going too far below freezing out I throw a small 50W aquarium heater in the RODI tank. I don't worry about the salt mix tank.
How much of a water change would you think to bring down nitrates?..and should i wait til my ammonia and nitrites hit zero?
To me, it looks like you are over 160ppm so a 50% change will get you down to no less than 80ppm. I would try to get it down below 100ppm prior to adding fish and less than 40ppm prior to adding corals.

You can add the Biospira any time. Just don't do a water change for a day or two after dumping the bottle in. You want time for the bacteria to cling to the surfaces in your tank.

Do you think I should throw the whole bottle of Biospira in?
 
Ok, will do, kinda upset tank is all out of whack, was kinda hoping of getting some fish in this week, been such a long process, been slowly building this tank since November

I understand completely. It often feels like keeping a reef tank is more art than science. It's not really true, but the science is so complex and has so many variables we have less control that we would like. I have seen tanks that were ready for fish a week after getting wet. I have seen tanks that have been set up for months and still aren't ready.

Just stick with it. I feel like you are close.

Ok I added a bottle of BioSpira 2 days ago..Should i just sit and wait now for awhile?..or test for ammonia and nitrites?

If you added it 2 days ago, I would test just out of curiosity.
