I know it's hard but I would take most the fish back to the store and start getting the tank running properly. The tank is only big enough for a male jack dempsey and several females really. Maybe 1 pleco.


I can't take them back bought them off of a people not a shop but I'm working on getting another tank soon.
 
OK, you need to get the tank cycled asap mate.
You can buy beneficial bacteria in a bottle in good stores and possibly something to buffer the ammonia and nitrite....
Nitrate is the end product and we all have this, try to keep it below 20ppm with water changes.
A cycled tank should be showing zero ammonia and zero nitrite, both are deadly to fish.
Aps filters are supposed to be good, you need at least 1200lph turn over. Don't take your current filter off the tank for another month or two once the new one is fitted, the beneficial bacteria that cycles/keeps your tank cycled lives mainly inside your filters.
Good luck pal and keep on them water changes until your reading zero nitrite and ammonia.
You need a test tube api water test kit with the ammonia test in it.
Don't over feed your fish, this will just make it worse, only what the fish will eat once a day and net out Un eaten food.
 
Also when you wash your filter only do this in tank water or a bucket of water that's the same temperature that has been treated with aqua safe or you will crash your cycle again.
Cycle works like this...
Fish waste (ammonia)- then beneficial bacteria turns it to nitrite- then more bacteria turn it to nitrate.
This happens straight away if you have enough bacteria in your filter and enough water turning over.
It's called cycled when you have enough bacteria.
If your reading any nitrite or ammonia your not cycled or are going through a mini cycle from adding too many fish too fast. The amount of bacteria is equal to the fish that sustain it..

Good luck anyway mate, first class in fish keeping over!-)

Thank you so much mate your a lifesaver . I was planning on doing 2 --- 2000LPH aps ef+ filters with the uv lights . That will give me around 4000 LPH turnover and I will pick up some of that bacteria asap. I am thinking of selling my silver dollars. They are kinda boring now compared to the rest of my fish. Any other tips you might have for me would be greatly appreciated. Thanks again for all your help I will keep updating this thread with what I have done . This community here on monster fish keepers is amazing you guys are the best .
 
No worries mate, filters will be great.

Just aim for a bigger tank, look on www.aquarist-classifieds.co.uk
Then search your local area with the search tab top left, don't add anything into the search box and it will bring up all the adds in your county with the most recent being first.
There are usually alot of large used tanks at good prices.
 
The mariae will not quite double that size it is now.
I also agree with justarn, since your tank is only been set up about 1 month, unless you used seasoned media, it isn't fully cycled, and if you keep adding more and more fish, it is guaranteed to crash, and the most sensitive fish will surely die first, and agree there are already too many.
A newly set up tank should only start with a few small fish until there is no detectable trace of nitrite or ammonia.

Thanks for your help I'm in the process of sorting it all out with new filters and a new tank to move some of the fish into . I am glad you guys have helped me out like you have I will keep you posted with how it goes . Thanks again for your help .
