Looking for help ID my new friend

  • We are currently upgrading MFK. thanks! -neo
Yes. All done now. I got this fish and tank by accident. And there gad been no fish care for a. Very long time. And I'm learning on the job. I now have a siphon and filter wool which I haven't changed yet. Any pearls re changing filter wool. Through them my way. I am a complete newbie
 
Nitrate zero! Will post some new tanks photos soon. I've given him a whole stack of rocks from the Kimberley. Not shale but pretty and about as close to Amazonian as you get in Australia.
 
Oic. Well good job doing your homework and what not. I'd definitely check Mfk general discussion if you haven't already. I'm hoping to catch some good progress on your thread. Good luck.

**** **** ****. what is going on? 18 hours since last water test.

Ph 6.2
nitrite 0
ammonia 0.25
nitrate gone from 0 to 120ppm

not fair!!! I'm new to this and should have a sensible tank. I don't know what kind of tank I have.

i think I have ****ed the tank.... Yesterday I cleaned the gravel. I took it out cleaned it because there was so much crap in it. I'm now thinking that this was the filtration system. The tank is completely home made. Fish shop guy and I thought there was wool and bio balls in the back of the tank. I bought wool for a filter change. I've now had a close look behind the fake rock wall and there are no bio balls no wool. There is no mat under the gravel so it's not a gravel filtration system. But given that this is the highest nitrate reading to date there was obviously something useful living in the gravel which I think I've killed.

ill try and draw diagram of tank. Note I do not know terms
 
That green filter looks like an Ehiem 2260/2262 canister, which is a GREAT filter..if it's still working.
looks like when you were messing around the gravel you kicked up a lot of debris and causing ammonia to rise then the filter is converting all the ammonia to nitrite then nitrate, so you seeing some ammonia (caused by all the stuff you kicked out from scooping the gravel manually, if you siphon them then this shouldn't happen since you will be removing them directly out of the water) 0 nitrite (the bacteria is doing great job at converting all the nitrite into less harmful nitrate) and high nitrate (can only be removed by doing w/c).
so frequent small water changes and siphon out as much crap as possible, stop feeding the fish until water is back to control, that's pretty much all you can do now.
the tank looks like it could use a good clean up too, wonder when was the last time any maintenance was done on the tank/filter. would be a good idea to clean the filter too, just make sure you clean it under tank water and not tap water so you don't kill of the good bacteria.
 
Thanks for prompt response so the green canister is the filter and what is the black box to the right of the picture/schematic?

everything looks completely sealed up. I'll visit the fish store next week and see if I can convince him to come and check out the piranha first hand and get some advice on the tank cleaning.

I've searched tank cleaning but nothing looks like what I have. Can you give me a generic term to search re cleaning eg should I search "canister cleaning"? Or is there a better term that will find this style tnk set up? Cheers and thanks again

40%water change nitrate at 50ppm
dont think tanks has been cleaned for years
yesterday's water test showed ammonia at zero after the gravel clean process - could the ammonia have spiked during the day, been converted to nitrite and now nitrate in the 18 hours since last water change and test? Cheers Jen
 
Ehiem 2260 filter cleaning <try youtubing that. Should be something on there.
