Heres the situation though. The tank has been cycled and established for months now. I recently had a problem with the tank water being very messed up and I had to do 30-40% WC for about a week and thats when the water was crystal clear. All of those water changes were done with a gravel vac. I just dont get it. Is there another way that tanks get dirty very quickly?
This is what you called a "crashed" system. Follow my sig.
 
Everyone that is getting on their soap boxes about the size of the tank just relax. I understand the size of tank that they need. I have a 125 sitting waiting to be set up but its old and ugly so I was waiting until I need to upgrade so I could decide if I can afford a 150 at the time or if I have to use the 125. As I said the largest is the RTC and he is about 5-6". I have another month or two before he needs to be out of there.

Now before you get on your soap box again about a 125 or 150 not being large enough, I also understand that and will be building a ]V[onster indoor pond.

While everyone on this site seems to be very knowledgeable which is why I posed the question but it seems like everyone just wants to give their input on tank size. I fully understand the size these fish grow to and will handle it accordingly and responsibly.

I am a novice at this hobby so I will admit when help is needed. I do not need help trying to figure out what size tank these fish need. I need to know why my tank keeps doing this.

Any more information on your filtration - are you using adequate mechanical and chemical? Could there be a dead fish or large chunk of food hidden somewhere in the tank or filter? The story seems quite strange as you tell it. At the very least, check out your filter really well, and add some new, quality activated charcoal.

When the water was "messed up", did you use any additives (chemicals)? If so, that might have shot your biofilter.

If you have ammonia and nitrite in an established tank, you have a problem. Along with finding the problem, you need to do daily 50% changes until ammonia and nitrite go away.

Thank you for helping with the situation I presented. I did not add any chemicals but it is quite possible that the ammonia destroyed my BB. I have 2 HOB filters which cycle the tank 13-15 times an hour. I'll do the WC until the water is clear again this time and see if it just keeps doing this.
 
what are you feeding your RTC? i feed both of mind massavore sink pellets. when they poo, it turns the water alittle murky. in a couple hours its clean again. you might want to start cycleing your 125 or 150 now, in 2 months the cat will be 9 to 12 inches.
 
The thing is people are mentioning the tank size because it is a factor.. I didn't mention it because I know thats the first thing people mention.

Also.. when you do your water changes / gravel vacuums if you clean or replace the media in the filter at the same time it can cause a mini cycle.. just something to keep in mind.

Which HOB's are you running?
 
Part of the problem is the design of a 60 hex itself. I wasn't blowing smoke, I was trying to point out the largest factor of your problem itself. A 60g hex is very inefficient when it comes to gas exchange at the surface which is crucial in the nitrification process in an aquarium. An airstone may help in this aspect.

I would get that 125 up and going as quickly as possible. RTC's grow very fast from what I understand, so it would probably be wise to get going on that indoor pond as well.

Something else that would be useful to know, what type of HOB's are you running? Do they have bio-media? If you don't have sufficient surface area for beneficial bacteria colonization, you'll be fighting to keep that water clean anyway.
 
To solve the excessive levels of Nitrate and Ammonia problems, I added aquarium salt and let the tank set up with everything running includes: filter, heater and powerheads to cycle the tank for 2 weeks before I introduce my fish in. Keep that in mind, the smaller the tank, the harder it is to maintain water quality. I had a 135 gallon tank set up at home with Oscar, Silver Arowana, and 2 Plecos in it and the water is still a little bit cloudy eventhough I did my water change every week.
 
i completely agree with hawkfish and gomezladdams, even if your tank is still cycling a heaxagon style is completely inappropriate for these fish, just goldfish-in-bowl syndrome. No matter the size, these species are well known for their messy natures and need a larger tank.

These words will come back to haunt you some day very soon. I would estimate that about 99.9999% of novice fish keepers that decide to buy one of the Biggest species of fish in the entire hobby right off the bat...fail

This current problem is just the tip of the iceberg

I'll give a member the benefit of the doubt at least once. When he says he's going to build an indoor pond, I figure I should at least encourage him to move in that direction.

But yeah, I agree. How does that old saying go? "The road to Hell is paved with good intentions..."
 
get a big high volume filter with sump....your going to need it later with the bigger tanks you are moveing them in, so why not now.......do some more research......
