The filter is allready installed. Its inside the cabinet. Its a external canister three stage filter/ pump combo. It filters about 500l per hour and costs about a grand!
I am thinking of installing a UV waterflowed canister to sterilize the water from algae and kill bacteria, but it costs about R700. The person at the fishshop said the filter will be efficiant enough. I'll install the UV light if the filter does not do the job.
Scrat please understand that i am talking from experience. That tank that you have is about 300+ litres u ideally want 1o times the water capacity turnover in your tank so a filter that does 2500LPH+ (will be too expensive in shop) to ensure that you are filtering effectively. Take into account that you are going to be keeping preditors and when they poo its gona be alot.
The filters are there to trap the dirt that the fish make and also biologically filter the water so convert the ammonia that the fish produce(toxic) to nitrite then to nitrate and then to nitrogen gas that leaves the tank.
The UV filter does none of that but removes any diseases that you may have in your water.
I would reccomend that you get a few more filters even the internal ones are fine (except for them being an eyesore) just to be on the safe side
Or alternatly if u keep a few small fish and make sure u do at least 25% water changes a week(minimum) the filter that you have would be fine
