Hi...
Hope someone can answer something that has been bothering me for a few weeks now

I have a 240 ltr tank with one Cichlid (Tiger Oscar) resident, I have had him for about 4 or 5 months now and he seems to be healthy and happy... he enjoys coming to the glass and watching my every move... he will even follow my fingers on the glass and if I put my face near the glass he tries to lip lock with me.

I use the API Master Test Kit and the readings remain fairly constant

Ph Low = 7.6, Ph High = 7.8, Ammonia = 0.0 ppm, Nitrites 0.0 ppm, Nitrates = between 5 and 10 ppm... still quite acceptable for Oscars.

Filtration System: Jebo 838 4 tray


OK the problem: in the past few weeks the water seems to be constantly cloudy and mostly has a light yellow / green tinge to it. Although all water tests indicate all readings are within normal and acceptable parameters.
I have performed regular weekly water changes of 30%... but the water stays cloudy.

About 4 weeks ago, the water was looking pretty dirty almost too dark to see into, so I performed a 100% water change, where I totally scrubbed the tank and removed the gravel and stones and thoroughly washed them, I then decided to separate the stones and disposed of the gravel and only replaced the stones and rocks.
Would this have caused me to loose any and all beneficial bacteria that would have been in the tank?

I also rinsed out the filter sponges and ceramic tubes in a bucket of the water I removed from the tank... which I then put back in the filter canister.

OK short question... is my tank cycling again?
or is this some other problem? I have thought about a bloom of some kind... but I have restricted his food to every second day to reduce any possibility and the tank light has not been on for a week and it gets very little natural light into the tank.


thanks in advance

Greetings and WELCOME to the site, red_101au!

I moved your question out of Introductions to this forum topic area so that it will be more likely to be noticed and addressed by those who are best able to answer it. Your question will get noticed much more here.

Introductions is for people to introduce themselves only, and we try to not ask questions there. We would appreciate it if you would return to Introductions sometime to tell us a little bit about yourself, if you would be willing to do that.

It can take awhile to get used to how to use this site!

Thanks!

Hi Thx for the welcome... yes sorry I didn't realize until after I posted that I had posted in the introductions area... again I apologize. I was just in the process of trying to find the pets section and place it in there and remove the first entry.

Hey, that's okay, red_101au!

Like I already said, it can take awhile to get used to how to use this site.

Now, it's just a matter of waiting until the right person comes along to address your question! That could take awhile though, because of the time of day and that fact that the best people to answer your question might not even be online here now.

Not only can it take awhile to get used to how to use this site, but using it can also take a bit of patience!

Thanks!

I believe your answer is here: White, Green and Yellow Cloudy Aquarium Water (http://www.fishlore.com/CloudyWater.htm)
