    Default First time fish owner - cycling and water changes


    0 Not allowed!
    Hi all, I have a bit of a story and a question. I got my tank on a Saturday night (Used a started kit, so TopFin 20 gal with their size 20 filter), set it up with API Quick Start, some sand substrate, and some Anubias and Java Fern. Went back on Sunday to get some slate to make a bit of a shelf and added more Java Fern and Anubias. Plan was to get fish on Monday so I'd have all week to monitor the tank from home before I start new job the following Monday. Started reading forums about fishless cycling, nitrogen cycle, etc. and panicked, realizing I hadn't given myself nearly enough time to do this right. I also read that the quick start had probably started my cycle, but without fish in there, that bacteria would probably just disappear. So I quick threw some of the food I'd purchased in to keep the cycle going. (Not sure if this was a good call or not)

    On Tuesday morning I took the uneaten food out of the tank and went in and had my water tested, noticed they used strips, but all the water parameters looked okay. My Ph was a little high at 8.2ppm and my ammonia was slightly elevated, sitting between 0 and 0.25, and my water temp has been sitting right at 80 since I started.

    I bought three Sterbai Corys that morning (Tues) and brought them home. Introduced them to the tank over a period of about 35-40 minutes. While I was introducing them I used the API Master Test Kit and re-tested the water, and got similar results to the lfs. The fish have been fairly active since I got them. They swim together, hide out for a bit, and then dance across the tank walls. I tried feeding them last night, but it went untouched so I pulled the pellet out. I noticed they were swimming up to the surface quite a bit, so I took some of my water out to cause more of a water drop from my filter to make sure there's more oxygen. I tested the water before bed got 0ppm ammonia, 0ppm Nitrites, and 0ppm Nitrates.

    When I woke up this morning I tested the water again. My Ph has gone down from 8.2 to right between 7.8 and 8, my ammonia is sitting between 0 and 0.25ppm, and my nitrites and nitrates are both at 0ppm.

    I added another food pellet and all three are huddled around it, under a plant leaf. (They're so incredibly adorable) They don't seem to be eating it, but I'll wait until they move to take it out.

    Thanks for sticking with me to this point. My questions:
    1. If my ammonia continues to read ~0-0.25ppm should I even do a water change? I was prepared to do them daily since I didn't cycle properly before getting the corys, but is there any reason to do a water change if it doesn't increase?
    2. I don't have any kind of aeration except my filter, but they do seem to go up for oxygen quite a bit and have been playing a lot in the bubbles. My plan was to introduce RC Shrimp in a couple months once I got the corys settled, so I haven't gotten a bubbler or the like. Plus I have quite a few plants. Do I need to be concerned about oxygen levels?
    3. They don't seem to like the pellets I have. TetraPro Cory Wafers. I know they could be not eating due to stress, but they seems to be digging in the sand for treats, so they do seem hungry. Suggestions?

    I've added a couple pictures, because they're cute.

    Test the aquarium for ammonia and nitrite daily
    If there are any signs of ammonia dose with Prime daily, double the dosage once it reaches above 1ppm for either ammonia or nitrite. Plants will eat the bound ammonia (called ammonium)
    Do a 50% water change when ammonia gets above 0.25ppm, you need to keep the ammonia no higher than 0.25ppm
    If ammonia is at 0.25ppm, do at least a 25% water change since ammonia continually rises.

    The pellets are hard, and cories look for meals they can easily swallow like bite size pieces. Let the pellet sit a few hours and see if it is still there.
