Hi there,

I have noticed that my nitrATE has slowly over time built up to 30 and then stayed at 30 constantly it did used to be at 5 when the tank was first set up.

My ammonia and nitrite are both reading 0

Will a few extra water changes help to bring this back down? I would like it down as much as possible.

I would just like to find out about a few diffrent easy ways this can be lowered back down in the tank.

Thanks

Water changes is an easy way to dilute pollution (in this case nitrates). You need to check your tap water for nitrates though, you won't get anywhere if it's got the same nitrate level :)

You may need to do more frequant or bigger water changes then you are currently.
Ideally your nitrates should stay under 20ppm.
How frequant are your water changes at the moment and how much are you changing?
while your there give us the rest of your details about your tank. Dimension,volume, filtration etc

My tank is 200ltr
Juwel internal filter with uprated 1000ltr hr pump
Fluval 4+ Internal Filter
Not sure of dimension but it is a Juwel Corner Tank
Lots of surface movement from both filters and air pump

Weekly water change of 50ltrs

Fish are fed 3 times a day on NLS.

I have never once had a reading for ammonia or nitrite so i assume its not because any of the filter pads need sqeezed more than i do it now. Is this right?

I will check my tap water later on but i assume the Nitrate is very low from the tap because my 2ft growing on tank is reading nitrate 5.

So upping mu water changes might be the answer?

I do have a old Nitrate removal sponge in the Juwel and i was going to change it a long time ago to a diffrent sponge but i never because the fish shop told me that the nitrate removal sponge would just turn into a normal sponge after it had used up all the nitrate removal stuff thats in it. Is this right?

Look forward to some replys.

Nitrate removal sponges are useless, save your money. Larger water changes are the best way to keep nitrates in check, provided your tap water is nitrate free, or at the very least, low. Try changing nearly half the tank volume each time. You really can't overdo a water change.

Feeding NLS three times a day is excessive. NLS goes a long way and most people overfeed with it, which is a leading cause of climbing nitrates. Try feeding once a day.

Higher temp = faster growing = more food = more poop = more aggression = less O2 in water, etc. If your temp is around 80, try gradually (over a week or 10 days) moving it down to 75 and start feeding twice a day.
