Would You Change Water?

[fluffycabbage]

My fry tank is fish-in cycling atm, nitrates are holding at 25 (have been last 3 days), ammonia 0, nitrites are 0.025 - would you change the water? Just wondering if that small amount of nitrites is just whats in the tap water anyway

If you want to try it with the fry today then yes do a big water change to refresh the water then move the fry over. Leave them alone for a few hours (3-6 hours ish). Then test the water to see what the stats are. Worst comes to worst the filter wont be coping and they may have to go back to the main tank. But at least you'll have boosted the filter abit so it has something to cycle with.

I would do a 50% water change right away. I have already said something similar in the common livebearer section but will repeat it here. When caring for freshwater livebearer fry, do whatever water changes it takes to keep your ammonia and nitrite levels at less than 0.25 ppm, which of course means that a reading of 0.25 ppm before the change is not acceptable. Livebearers, my own personal focus, do best when kept in a tank where their water is changed frequently, even if measured parameters are OK. The speculation of livebearer breeders is that the fish release hormones into the water that inhibit the growth of the fry, and that changing lots of water promotes the growth of the fry. Our experience bears out the veracity of that assumption, even though none of us actually can measure any such hormones.

I fixed my post FishieWishie. I had not noticed the extra 1 in my 50% suggestion.
