    Hello there, Im new in the hobby, I just started my reef tank, 20 gallons, I started my cycling period about 25 days ago using Brightwell Micro Bacter Dry Rock Starter Kit, I made the cycle, brought down Ammonia and Nitrite to zero and my Nitrates where reading at 80PPM, the instructions on the...

    Concentration of Ammonia (ppm) per Ammonium Chloride Dose (g) and Tank Volume (gal)

    Hi everybody, This thread may not be relevant to everybody, but to those who need it I think that this could be extremely useful. For those of us that opt to do a fishless cycle, I have created a quick reference dosing chart to achieve whatever concentration (ppm) of ammonia you desire by...

    So Im in the middle of cycling my tank with fish in it. Checking the water parameters it seems like the nitrites and ammonia are very high, which obviously it’s supposed to happen, but it seems like it’s really not going down. Is it possible to do a 50% to 75% water change in the middle of...

    Cycling thoughts

    So it’s been a week since I started cycling my tank with Dr. Tim’s and the nitrite levels have been off the charts since the second day (meaning that the levels were unreadable on the chart since they were so high) two days ago I raised the ammonia to 1 ppm just to feed the bacteria and left it...

    Ammonia not spiking during cycle

    So 2 weeks ago I started my 69 gallon tank with dry Marco rock, live sand, Dr Tims One and Only, and a cocktail shrimp. After 3 days I began testing and I seen no real rise in ammonia and a very small rise in nitrite. At the 1 week mark I pulled out the shrimp and replaced it with a raw shrimp...

    Ammonia & Nitrate Crisis in QT!

    Hi everyone! Since you guys have been SO helpful in the past, I thought you would be the best people to go to! Btw, sorry the post is so long! I have had a goby/shrimp pair in a 10G QT for almost 2 weeks. From the moment we put fresh RODI water in it (from our RO/DI unit), ammonia has been...

    During cycle, nitrates have risen to 30ppm but nitrites are stalled at 1ppm

    Hi all, I just finished up week 6 of our cycle but am still detecting nitrites at around 1ppm (using salifert test kit. I have no ammonia, or very little, according to salifert ammonia test kit) but my nitrates have risen from 5ppm on August 5th to around 30-35ppm now. Nitrites have...

    Chloroquine Phosphate and Ammonia in a 75gal QT

    I am on day 3 of CP QT and worrying about ammonia. Fish are looking and acting fine, but I am seeing debris on the bottom. Red Sea Ammonia test kit is reading .4, after adding Prime the reading is still .4. Is there an accurate way to test ammonia with CP present? Did the Prime take down...

    After this, there is no turning back. You take the blue pill - the story ends, you keep believing that nitrate and phosphate are the cause of your algae problems. You take the red pill - I show you how deep the rabbit hole goes. This image was created by @Fish_Sticks, ©2019, All Rights...

    Sustaining a newly-cycled unstocked tank?

    Hi all, I did a fishless tank cycle and am getting some nice diatom growth. I am going to wait until after the first of the year to stock my tank, but obviously want to keep the cycle going. I'm assuming I need to continue to add some ammonia every so often to keep it going? Has anyone done...

    New Live rock leaching ammonia

    I bought around 7 pound of live rock from a local reefer the rock was sitting out of water but was still moist for about a day and had some green hair algae on it. I scrubbed all of the algae off and let the live rock cure in a bucket for about 10 days with a powerhead and heater and have done 2...

    Ammonia in QT

    Not sure if I should post this here or in the disease treatment or tank emergency forum, but it's mainly a chemistry question, so here I am. I got a beautiful purple tang about 4 days ago and put it in my QT. The QT was cycled from the last fish I got but had been empty for 2-3 weeks (with the...

    Too Much Matrix?

    So, I recently bought a 250ml bottle of Seachem Matrix. It says on the bottle that I should use the whole bottle for 25 Gallons of water. Currently, my water volume is about 13 Gallons. Can I use the whole bottle? Or should I follow the instructions? Also, in which part of the sump should I put...

    hey everyone. I experienced some die off in my tank and have an ammonia spike. I know the cause and working to fix it. The closest store to me only had API ammo lock. I see that’s it’s saltwater safe but is it reef safe? I have some corals zoas and euphyllia. I want to neutralize it so it...

    Tank crashed

    I started a thread in the emergency threads the other day. I just transferred all of the content/livestock from a friend's tank to my tank last week. All was well, but ammonia started to skyrocket. Well, pretty much everything is dead now. Deaths included the CUC, 2 peppermint shrimp, 1 Skunk...

    Ammonia spike in transfer tank

    I just took over a tank from a friend. She gave me about 45 pounds of live rock, 2 ocellaris, 1 dottyback, 2 striped damsels, a decorator crab, and 1 cleaner shrimp. She had them all in a 40-gallon breeder with a cheap protein skimmer. I just moved it all to my 50-gallon with a 20-gallon sump...

    What in the heck is happening?! Where is my ammonia going?!

    My cycle completed, and I did a complete water change, the nitrates having skyrocketed. Everything (but the pH..) showed up at zero. Nothing at all. So I added a few drops of ammonia. Ammonia began to read, then faded. But nothing else changed. I've noticed this yellow/peach layer developing on...

    How a noob is cycling tank

    Hey guys! I set up my saltwater 10g tank, using live sand, Bio Spira, and Dr. Tim's Ammonium Chloride to start. I put a way too much of ammonia, but it's hard to tell the exact ppm. My question is, will I need to do a partial water change after cycling? All of this excess ammonia will be...
