I had a GT, JD, Blackbelt, pleco, and a catfish in my 90G tank for about 6 months. I had be cycled already and everything. But about 1 month ago I had to move the tank into differnet room. I took out everything, all the plants and rocks, ortaments, filters, and heater. I just put them off to the side to start taking all the water out. About 2 days later my fish start acting strange. Then started swimming around like crazy hitting their heads on the glass and then they would just fall to the bottom of the tank and gash for air. They did this for about 1 week or two. Yesterday I walked in to find my GT, balckbelt, catfish all dead. Now all thats in the tank is a 3 inch JD. I have no idea what to do. I did a 50% water change last night and now the water is even clouder then before, like it's going though a cycle again. The ph is at 8 and the ammoina is at 0. I think it might have been the nirites in the water but I have no idea.

I seriously need some help becuase this is really stressing me out. What do I do? If its going though a cycle again what do I do about it? I really haven't done a fishy-cycle before. Please help me. I have a 100G filter and a 35G filter going it the tank. Thakns
 
You had a bad day . Take a deep breath , And .Start from the beguning , Did you use any sop , was water temp good ,Did you add any water treatment .
:confused:
 
ammonia is at 0? what are nitrites and nitrates? if you are showing nitrites then you are going through a cycle, if there are none then that is not the problem.
why did you move the tank?
did you reacclimate the fish to the temperature of the new water?
how often did you do water changes in the past? (when a tank doesn't get regular water changes, all kinds of things build up in the water, making the tank water very different from tap water, and therefore putting the fish in 100% new water can shock them).
were the ph of the old tank water and new tank water the same?
did you remember to use water conditioner?
do you have gravel or sand? how often did you clean it?
put some water into a clear glass and hold it in front of a piece of white paper - is there any greenish coloration? you could be having an algae bloom.

all you can do until we have more info is more water changes.

I really have no idea what the nitrites and the nitrates are because I haven't had a test kit in sometime. I thought I had everything under control so I didn't get a new one when it was gone. I haven't had this much bad luck with a tank in a long time. I have 5 all together. I moved the tank because the sun was hitting it all the time for about 3 hours a day, and because my wife didn't want to there anymore:huh: .

The water stayed the same, I just changed like 25% of the water when I moved it.

I usually change the water in all my tanks about every 2-3 weeks and about 20-25% of the water.

I actually found today that the ph of my tap water is about 9. but in my tank it's around 7 to 8. Before I add new water how do I get the ph down to a good level?

Everytime I do a water change I add a chemical called AquaSafe. This is a water conditioner that I use.

I have gravel in my tank. I clean it when I do water changes. I use a gravel vac to clean out the gravel.

I know that I had an algae bloom because of the sun hitting the tank and that why I moved it in the first place. But it really never wentaway all the way. My water has had a greenish tint to it for about 1 1/2 months. I've tryed treating it but I just comes back.

I need help and everything that you can tell me because I need some help. Thank you for the help and I hope to get some more inforaiton from you in the furture.
 
you should def. pick up those test kits to see where your cycle is.

as far as the ph, it's probably not that big of a deal, when water first comes out of the pipes it has a lot of dissolved gases because it has been under pressure, once it has been out of the pipes for a few hours (overnight or so) all those gases come out and the ph drops down. if you wanted to add water that was the same ph you would have to get some buckets and let the water sit out for a while. there are several people here who use aged water on thier tanks regularly. you should definitely be doing more water changes anyway, at least 25% every week, more when you restock the tank.

you say you only changed out 25% of the water when you moved the tank - what did you put the other water into when you moved it?

your timing is kind of confusing. if it happened a month ago and your fish just died then i don't know what the problem is. any power outages? if it was just one or two weeks ago, it could be some kind of reaction and poisoning from toxins introduced into the aquarium accidentally.
 
I don't know, no power going out lately. So if I go pick one up tomorrow and test the water and there is nitrites or nitrates in the water then it's going though another cycle? What do I do during the cycle? I mean how do I help it though the cycle fully, so in like a month or so I can add the fish that I want? So I need to do more water changes and age the water before I add it to the tank? That sound do-able. Thank you so much for the help, I really thank you.
 
You will be stuck in a fishey cycle. Get your test kits, do water changes to keep ammonia and nitrite below .25 and nitrates less than 20.

You could push the cycle with somr bio spira or media from your other tanks that you mention.
 
So if I have no nitrite/ammonia in my 90G tank that means that I'm ok and that the tank is not cycling. If it is cycling all over again then I'm going to leave the JD in the tank throughout the cycle. Also you say that it takes about 30 days to completely go though a cycle? Ok, how do I know when it's gone cycling? And when it's done cycling how do I stock the tank again? Because I plan on adding a convict 6 inches, JD thats 5 inches, and a oscar thats 8 inches. I won't add them all at the sametime but over a period of three weeks? Thses three fish live happily in a 100G that is owned by my dad. When should I do water changes if my tank is indeed cycling again? Like every other day?
