You never want to just take out the old media and put in new without seeding it, it will cause your tank to relapse and you'll basically have a 'mini-cycle' where you'll experience ammonia and nitrite spikes that, if not caught, could kill your fish.

You want to make sure that when your media starts to look dirty that you gently clean it in emptied tank water during water changes. I know for mine i have two large sponges in mine and some bio ceramic balls so when it looks dirty or there is debris caught in the filter I'll dunk each piece in my water bucket with the dirty tank water and gently wash them clean before putting them back. When it comes time for me to change sponges I'll remove one and place in a new one (great thing about haveing a filter that requires two sponges and not one, double the space woot woot) that way the 2nd one can seed the knew, then after awhile I'll remove the last old one and put in another new one. :)
Hmm well since I have just a standard filter I wonder if I could slide in a new filter while leaving in the old filter for a few days..

I agree with everything dragon said. Very good advice.
I buy cut-to-fit filter pad material and keep an extra layer or two in each of my filters. Then when the filter cartridge disintegrates and has to be replaced, I'll keep the extra pads in with the new stuff. I only change cartridges maybe once or twice per year.
Good luck!

Well I got the liquid test kit and it read .25 ammonia, 0 nitrites, and 5 nitrates. I still don't know how the ammonia is going down but I continue to has no nitrites?

There might be bacteria there, just a little bit, eating that ammonia and creating Nitrites in just too little of quantities to be picked up by the test kit. It happens :) Better that it's going down and not up right? hehehe

reduced ammonia & no nitrites, ...

could be the limits of your test kit (not likely)
could be you've got the bacteria in place to do that process in sufficient supply already (more likely, but i don't think it's realistic, but who knows)

after that, ... i don, lots of blanks from this mind.

on plants and ammonia

in all my research i have not heard of plants consuming ammonia directly
i have heard the internal pH of plants is expected to be low enough to ensure it's all ammonium
plants will directly use ammonium

ammonium is not detected by any test kits i know of, if looking at your test kit for ammonium it lists ammonia and a number relating to your pH, ... this turns into math so you can get an idea of how high things are by a mathematical multiple when your pH is lower

I tested my water and guess what?
It has .25 ammonia in it. I also tested the tank 24 hours after I had changed the water and it was still at .25...It might be ammonium that the test is reading as ammonia? I hope so.. I'm not really excited to try and do water changes with store bought water

might be the lighting you're reading your test results with.

that's my first default thought when every test reads the same and you're sure it should be lower.

test kits don't test ammonium, and the ammonia that is tested is only going to be a fraction based on pH the rest being ammonium. the two convert back and forth in the aquarium easily as H ions roam around back & forth

if your pH is changing, (and the water your adding has no ammonia/ammonium), ... a changing pH can give you different readings leaving you scratching your head twice as hard wondering WTF is going on here?

Haha yeah, well I've tried looking at the tube in different lighting places around the room but it still looks like .25. It's at the very least not at zero and continues to remain the same color so..
I'll check my pH again to see if it's been changing..

i had a sudden thought.

if your ammonia test kit also conditions the water to a high pH and you have enough ammonium in your tank ...

everything i've come across ammonium is safe, but ... you can't remove/process ammonia to get only ammonium, it's fraction ratio thing, remove X amount of ammonia, the ammonium will just balance out till the same ratio exists again (i dono if i said that clearly)

i don't know if this would be good or bad as a low ph (i think 6.4 or 6.2 and lower) your tank will have no significant ammonia, even if it's all ammonium, it will stay ammonium and you'll have happy fish... a test kit changing ph and testing will then give a higher reading then what your tank is actually experiencing.

again, this is just a sudden thought, does not mean it's real

Well I do have high pH..Are you saying that because of this that means that what's in my tank is actually ammonium?
