Could it be something with the Test? I heard API isn't the most accurate and the numbers don't seem to add up. The 20ml for the 20gallons should be around the 3ppm according to their website, so if all that got processed I should only be around 10.2, but I still have some Nitrite left. It claims for the 5 day cycle, so could I be near the end of that? If so should I just WC to drop the Nitrates?I think 1ppm ammonia = 3.4ppm nitrate
Thanks! So far I only added the nitrocycle and fitz, but have copepods sitting and waiting to go in (hopefully they will stay alive). my plan was to add them in and dose phyto to try to kick the tank off with a large number of pods. The numbers just don't seem to add up. Would high Nitrates kill off the bacteria? Shouldn't I be good just off of the single-dose? I read a lot of times there is a 2nd mini cycle due to the bacteria being inactive after the 1st cycle and when the routine fish poop happens it kicks up.Hi newbiereefs,
I would suggest that you hold off on doing any water changes for a few more weeks, unless you already have livestock, in which case please let me know and I'll give help you out on how to determine when to do them and how much to change at once. Assuming you do not have any livestock and have a protein skimmer running, you will want to wait until at least the 2 week mark, however, waiting longer may be beneficial depending at what your water parameter tests are reading at the 2 week mark. If you do not have a protein skimmer running, I would advise doing a water change at the 2-3 week mark depending on what your waters parameter tests read.
Whether you already placed livestock in the tank or not, I recommend making a trip to your local Petco and picking up an Instant Ocean 250 mL BIO-Spira bottle (the large bottle) from Petco and emptying the entire contents of the bottle in by adding half of the bottle at once the day you buy it and the rest the day after. Fritz-Zyme TurboStart 900 is great and I have used it in the past, however I have discovered that it occasionally needs to be repeated a week or two after initial dosing due to test results starting to read high in all three parameters. When I have done as I described with BIO-Spira, I have had a perfect track record of near immediate cycling without issues later down the road. Its incredible stuff.
No matter what, no water changes you do for right now should be "large." Any water changes you do should be no more than 1/3 of the entire tank volume.
If you have not added any livestock yet, I would highly suggest not adding any yet until parameters have gone to cycled levels and stayed consistently reading at those levels for at least a few days. If you do add livestock at that point, it should be minimal.
If you have already added livestock, no judgement here! We've all done it (many of us more than once) and all have learned a lot from starting our tanks that way.
I hope this helps!
Yeah that's my confusion as well. I did the initial dose of ammonia and would like to add the phyto and pods today. Should I keep adding a little in? I'm just getting concerned with all the nitrates it is making.Are you dosing ammonia? You are good to go to add the pods or livestock. The API kit notoriously reads .5 and you may be waiting months for it to read 0 if at all. Nitrite is not a concern at this level.
Curious as to why more bottled bac would be needed? When using bottled bac, you are able to add at least one fish after adding the bac. This is why you pay for it. The bacteria will be able to handle the load of a single fish maybe two. Is it safe to wait? Yes, but not needed. The only purpose of waiting for weeks is when you do not use any form of bottled bac and cycle naturally by using shrimp or ghost feeding.
Absolutely, and in fact it applies to most nitrate tests: . The nitrate test kit converts a small fraction to nitrite, before reading that as a proxy. So when you have nitrite present, nitrate can read erroneously high.Could it be something with the Test?
Thanks! Did you keep adding it in at all? Or just the two, wc and go go goJust to clarify Nitro start is the ammonia source. I know what kit he's using and have had great success with it . Normally 8 day's completes the cycle in my experience with it
Twice ones at the start and once 2 double check ammonia consumption was happeningThanks! Did you keep adding it in at all? Or just the two, wc and go go go
As long as nitrite is present, the nitrate test results are meaningless. The nitrite gives a very high false positive in the nitrate test. The goal now is to monitor the NH3 level. When it is gone, the system has a healthy population of nitrifying bacteria.
