I have a 100 or 110 gallon tank (Not sure on exact size). here is the background I got the tank 10 years ago, and moved away about 5 years ago and left the tank with my parents. I bought the house (which included the fish tank). But my parents did not take good care of the tank. I bought a new filter an emperor 400. Vacuumed the tank, and cleaned all the algae off the rocks.

Now my Nitrate levels are extremely high. Not sure on exact number but had tested at the fish store. I did a 25% water change twice, and still very high nitrate level.

Can the high nitrate level be because the filter is to small, or can it be because there is still to much fix poop in my rocks? My bed is some type of crushed coral. The bed has been in the tank for the whole time the tank has been setup. Right now I have on Chichlid and an algae eater in the tank.

Sorry to ramble on, and if this is in the wrong forum group please move it, and thanks in advance to answering my question.

Ok for that pacticular filter, it is only for aquariums up to 80 gals. It's flow rate is 400 gph.

I would say you need a larger filter. Also when trying to reduce nitrates in an aquarium, you have to know what the number value is of your nitrates is in order to determine how much water to change. Ex... If you tank is reading 40 on nitrates, you want that number down to 15. Since there is always nitrates in water, you will never be able to get it down to 0.

So lets say you are sitting at 40. A 50 percent water change will take it down to 20 or approximatley, (in theory).

If that being the case you do another nitrate check in a couple days, take that number and do another water change until you are seing 15 or less. Do NOT do a 100 percent water change in the same day just to reduce nitrates. You will end up stressing your fish out. There is an exception, that's if your nitrates are reading over 80. Then you have to do 75 percent water change because your fish are in severe danger. Check in a couple days and do water change according to what your nitrates are reading.

Typically, we do a 25-33 percent water change every week until you get your numbers in check. Then after you establish your numbers, you can move up to one time every two weeks.

Understand?

Can I keep the emperor 400, and add another filter that is good for like 50 gallons? Which then if you add 80+50 gallon filters will give me a total of 130 which will be bigger than my ~100 gallon tank.

Thanks,

you can add another filter plus add some power heads to stir up the water more there liek $25 and some pump up to 100 gph so that can help to add to filtration if you place a spoge on the bottom

Good suggestion! Powerheads are a great way to help dull down on nitrates. The more water movement the better at keeping your nitrates under somewhat control. I have a powerhead at each end of my tank. Powerheads also come with (forgive me for not knowing what they are called) a tube that connects to them with what appears to be an airstone connected at one end. It puts oxygen into the water and you can control how much with a little lever kind of thing on the hose. Well to be honest I don't know if all powerheads come with it but mine did. I got the Top Fin brand. I bought little sponges to cover the intake under the powerhead and I rinse them out every few days and they basically act as another filter.

yea the thing your talking about mother is it realy sucks air in and is liek a 2 in 1 thing its like having a bubbler and a powerhead in one i got these

https://www.thatpetplace.com/pet/group/11463/product.web

you can set the as undergravel but i dont like it like that it comes with several attachmetns so you can just use it as a regular power head and they work good and catch big debris

These are what I got. This paticular one is for a 30 gal tank but they look the same. They don't show the little hose I was talking about. But they do have directionals on them which are real handy but must admit they are very hard to turn to position. But they work great. The bigger powerhead the more expensive, that's for sure.

One more thing when dealing with powerheads and sand. don't put the powerhead to close to the bottom of the tank where the sand is or it will suck the sand up into the impellar.

absolutly not and I don't suggest undergravel filters. They do not work as well and they need to be cleaned every now and then which means tearing down one's aqarium.
Here is one of my powerheads circled in red.

Malawi mother you said you bought little sponges to put in the power head, what kind of sponges did you buy? Did you buy filter sponges and cut them down? I don't think you can use reguler/household sponges because they may conatin some type of cleaning solution (correct me if I am worong).

Thank You

The sponges I got are for powerheads. There are all kinds of sponges for powerhead filters but these ones are for a different kind of powerhead but they work just as well on my powerheads. They work great for little cichlids that have a harder time fighting for food, when you feed some of the food goes right for the sponges and the little ones will eat from the sponges with no injury to themselves. Here is a picture of them. They are Elite sponges but I don't remember the brand name. The LPS carries all different kinds so you may just have to go and look. These one's paticularly have a hole in one side that slips right on to the intake of my powerheads.

yes, NO household sponges for any use in the aquarium, not even to clean it with. A lesson I learned a long time ago.

i would suggest when putting another filter on get another emporer 400 if any thing you want more filteration on the tank that big and it doesnt hurt to have more bio filteration for the tank to hold cycle better.

I am getting a new filter this weekend, probably the emperor 280 (I think that is the smaller size), or an aqua clear filter for about 50 gallons or so. My local fish store recommends the aquaclear filter. I still have not researched which I think is better.

I have limited budget right now, but if I can get a total of 130+ gallon filter capacity I think I will be OK. Plus my dad just bought me a power head with 170 gph capacity.

I am buying my new filter tomorrow, I have a question. After I add it how long should I wait before I change the media on my old filter (the emperor 400). I have been working on changing my water over and vacuuming my tank to lower the nitrates.

In vacuuming my tank I found the cause of my high nitrates. Since the tank had not been cleaned in a very long time, there was a lot of fish poop in the gravel.

I have down 3 25% water changes, and still need to vacuuming at least one or two more times to get all the fish poop out. I think it is fish poop, it looks like dust that I have been vacuuming up.

I know I shouldn't change the media in my old filter at the same time I do big water changes. I hope I did not confuse you all to much with question/post. My question is as follows, How long should I wait to change the media after a big water change, and adding a new filter in the tank?

PS I have been taken pictures during this whole process which I will post when done.

Ok you can either wait 6-8 weeks before changing the old filter media or

You can cut a four inch square off the old media and stick it in with the new media. Do NOT rinse the old media when doing this. Leave it's slimy coat and just put in with the new media.
This is the best way to establish new bioshpere quickly.


Important note. Every 4 weeks or so, vacuum one side of the tank. Never both side in the same week. The gravel hold important bioshpere and never ever do it while changing old filter media.

Now here is the thing about water changes when doing filter change. At all times when you put a new filter in, you should also be cutting a 4 inch square off old media to keep biosphere strong. I have heard several people say they have heard never do a water change after doing a filter change.

I have never ever gone on that info. When you do a water change, you should only be taking the water off the very top of the tank. Not in the middle or the bottom. The top is where all the dangerous ammonia and nitrates can mostly be found. I always do a water change BEFORE I do a filter change. Maybe that's what the difference is. When I do a water change and filter change, I do the water first to take old ammonia out or nitrates and then when I put the new filter in the canister filter, all the old junk comes out into the water and the filter sucks it back up leaving valuable biosphere in the water.

So key points
-only half the tank vacuumed every 4 weeks.
-only take the top water off during a water change
-and when replacing old filter media, cut 4 inch square and place with new filter media.

Hope that helps.
