I've gotten back into the hobby and I totally cleaned out my 10 gallon which housed one lone bronze cory. I kept the media, but ditched all the substrate and cleaned off the decorations. The tank was a real mess so I unearthed another 10 gal I had, decorated it and put bronzy back in along with the media. Then I decided he needed buddies and got 2 peppered cories, 2 sterbai cories and 2 black kuhli loaches. The sterbai cories are super small, 1/2 inch if that. The peppered cories are about an inch. I also bought a new pump with bio-wheel - Marineland Penguin 100 and put the media in that. I also added a few pieces of ceramic media to help house more, cuz more is better right? I did all this on Sunday, except for the filter. I got that Monday. Also on Monday I checked params and now have a ammonia spike. I've been doing approx. 1/2 tank water changes and dosing with AmmoLock, which I had for the pond because I wasn't sure if the Prime I had expired. Google searched yesterday and found out that Prime is good, so I dosed with that last night with the water change. I had also drastically reduced feeding due to the ammonia. 3-4 ppm Ammonia - will Prime protect that high? AmmoLock will protect to 4 ppm .50 ppm nitrites 10-20 ppm nitrates - color is hard to determine with my old eyes Here are my questions: 1) Hindsight (story of my life) I probably added too many fish at once correct? 2) Am I overstocked? 3) Will the bio-media start compensating and cycle for the additional load or will I have to remove fish? 4) Ordered safestart, but read that I can't add it with an ammonia binder. Is that correct? I appreciate any and all help!
