[sjm1978]

Hi i set my 24g aquapod up 3 weeks ago today i used pre-cured fiji from liveaquaria.com. my water tests at salinty 1.025 ph 8.3 ammonia 0 nitrite 0 nitrate about 20 i have a blue/green chromis in there. im starting to get major brown algae everywhere sand glass rocks. should i be doing water changes or should i just leave the tank alone? if i should be doing water changes how much should i change?

yes- imo 10 percent and test

Are you done with your cycle? If so, yes.. 10%. If you are still cycling, I recommend not to. Let the tank do its thing.

I think water changes are fine at any point. They are useful for a number of reasons. In this case, I'd consider doing one or two larger ones, maybe 25%, to help remove any metabolites from any decay that might have occurred.
