So this FOWLR 100g tank I got has a Bio-Filter built into the back of it. I've never dealt with this kind of filtration before. Personally, I don't think it works very well. I hope this makes sense, The rundown of its flow: It starts with an tall compartment that has a filter media, that blue/white kind that you cut to fit. Next compartment has a heater, then if flows over a long horizontal compartment with a tray and more of the same filter media. Under that is full of those blue bio-balls, and a pump (it's on the bottom so I never saw it, don't know what kind but it seems to be working)

I have added a pouch of carbon on the tray part, I keep a polishing pad in, which works great at getting all the little stuff out of the water. I also add phose-zorb because my phosphates are high, it seems to be helping.

Should I ever empty everything out and clean the whole filtration system? I usually only rinse/change the filter media.

Oh yea, and is it normal for it to run low on water and not see the whole tank run low?? I add water to it weekly, but the front of the tank doesn't look low.

So like I said I don't like this kind of filter but I'm kinda stuck with it, what would you change or add?

To eliminate the question....I don't have a skimmer, plan on getting one eventually.
 
The display section of the tank will be the same all the time and the tank will only show evaporation in the back because the display overflows to the back.

What I would do is remove the bio balls and then come up with a way to remove all of the filter pads and make a tray to hold a filter sock in in its place. You can also keep media in one of the trays.

Dont know your whole setup or tank husbandry habits but removing the bio balls and adding a skimmer should help a lot you can keep the pads if you dont want to or dont have room for socks but you must clean or replace them like every 3 or 4 days same thing goes for the socks. The goal is to remove the organics before they get broken down into nutrients. Bio balls do the opposite to some degree they tend to trap detritus and break it down into nutrients

I'd remove the bioballs gradually to prevent any sudden changes in the water chemistry.

Yes good thought

I'm in the process of removing mine and so far haven't had any problems. I took out three yesterday, will take out another few next weekend and remove the rest the weekend after that. Good luck!
