Hi guys thanks so much for the warm welcome and advice.
@RedneckPoodle I went on the site but they did not list my Filter so i selected user defined and inputted the power of it on the box its says MAX 1000l/h. I will attach a pic of the filter.
After adding my 17 fish (1 betta splenden, 4 pygmy cory, 1 apple snail, 1 ghost shrimp, 5 chilli rasbora, 5 white cloud mountain minnow) i got the following results:
You have plenty of aquarium filtration capacity.
Your aquarium filtration capacity for above selected species is 949%
Recommended water change schedule: 24%
Your aquarium stocking level is 67%
Not sure if its good or not?
If any other feedback can be given id appreciate it. ps the list of fish I got off this website: http://bettacare101.com/tankmates/
