Hi everyone, a week from today I got a new 20g tank. I have been cycling it fishless. All of the levels look good and now I'm wondering if I could go ahead and put two fish in it for about a week then add some more. Should I do this?

Those readings would indicate a completed cycle, but HIGHLY unlikely that it happened in 1 week. How did you test the water? How specifically did you do the fishless cycle?

I would suggest getting the water tested at a reputable fish store to make sure.

I used some of my water out of my other 20g and i took my filter cartridge from it and put it in the water for a minute. It does seem unbelievable, but I did everything it said to hurry up the process. I also use test kits for these things.

I have only been at it since 1978 and learn new stuff all the time. Matter of fact I just wiped out some Saltwater stuff due to being complacent in my water testing, I just murdered two fish and am on the way to doing the same to a coral well. Makes me ill that I could let this happen!!!!!!!!!!

Yeah, I got complacent in my water testing, this SW tank had been spot on for over two years. Always about 8.1 to 8.3pH. This tank has a ton of buffering so I thought it was impossible for the pH to dive. So for two weeks I didn't test pH. Well some how I must have messed up in my dosing calculation and the pH dropped to 7.3pH-ish. I still feel ill.

There are numbers under or next to the colors. I have never used the strips - people say they aren't as accurate. I have used strips for testing things in the medical field and I know how carefully they need to be handled - any moisture can ruin them and it is easy to drop a few out of the container and contaminate them. Also if you do the math, in the end I am sure the liquid is much cheaper. OC also recommends an ammonia alert disc you can get for your tank which I think would be a really good deal. Just remember that won't solve all of your problems.

Yes, the ammonia, nitrite and nitrate are your most important. The API liquid test kit is probably the best way to go - it also includes pH testing, but that is not as important in your case (or mine). The cheapest I have seen the kit is $23 I believe. Petco has it on-line cheaper than in the store, but you need to pay shipping unless there are some other things you need - they have deals on shipping. It comes out of CA very quickly. There may be other places also. The problem I found with buying the chemicals piece by piece is it costs a lot more. I am going to guess if you buy all three separately they will cost between $25 and $30, but you can check.
