Should I do another large water change?

So, I've noticed a spike in my nutrients in my 24g nano. I did a 5 gallon water change 2 days ago and today I'm seeing Nitrates pushing 20. Ammonia and Nitrites are zero. Without getting too far off subject, I'm just wondering if there is any reason I shouldn't do another water change tomorrow of 10 gallons to keep the nitrates below 10 for the sake of the livestock.

It's a very new tank, cycled with bio spira (and dr tim's actually). I saw a bit of algae pop up, but it looks like it's died down since (maybe causing some of the nitrate rise).

Anyway, what would you do? Let the nitrates rise or go with the agressive water changes every few days to keep them below 10?

Possibly relevant info

5 hermits

You can always do water changes and they are a good way of reducing nutrient levels..
Change away to keep nitrates low if you want..

20 isnt bad at all for a new tank but it can get out of control quick... Id just recommend you stay with a 5g change once a week at this point and see how it trends

Being blunt and having fun

Thanks for the feedback! I'm going to check my nitrates and probably take your advice if they haven't risen much over night.

How old is your tank? Have you properly cycled it? When did the livestock go in and how long before each addition?

Water changes are the easiest way to reduce nitrates.


The only thing to fear is fear itself....and spiders.

Just make sure your fresh saltwater is warmed up close to the tanks temperature. Have you tested your fresh saltwater for nitrate? I had a buddy who got some bad water and it started a algae nightmare.
