From brackist to fw....need to cycle again?

[1puff]

I'm going to be converting my brackish tank(1.003)back to fw. Will it go through another cycle?

[Pufferpunk]

Not with that small of a SG change. What's up with the FW change back?

Lorteti.

Ar specific gravity 1.003-1.005 the nitrification bacteria are still FW forms.

You'll probably want to do it in two stages over a few weeks to prevent a partial dieoff.

i`ve done 2 50% water changes since sunday and the sg is still showing approx 1.002. Should i rinse the filter media?

[Pufferpunk]

Don't bother, that bacteria's been through enough.. Check your hydrometer against your tap water.

[1puff]

if the bacteria is still fw form at an sg of 1.003, why would it get affected?

[Pufferpunk]

What we've been stating is it will not be killed. Doesn't mean they won't get stressed. Stress can kill. Rinsing out the bacteria in your filter media is not a good thing to do at the moment.
