  1. damsels are not mean

    Can I test for nitrate in freshly mixed saltwater as a "control" to make sure my test kit is working properly?

    Just got some new hanna checkers today and tested high range nitrate. The result was too high to read, and the instructions say to dilute it if that happens. I cut the sample in half and added more water, same result. After a second halving I got 52! This result seems ridiculous as I'd expect...

    Got my ATI results back and need help with a game plan.

    I just got my results back. I took my sample the same week that I started a chaeto reactor so know my nitrates and phosphates will come down, but am concerned that my nitrates are 135x my phosphates instead of about 10x like I see being ideal. I’m thinking of starting to dose NoPox but am unsure...

    What are Acceptable Nitrate Levels to Acclimate Fish

    I recently purchased a 65 gallon Red Sea aquarium on Offerup. I currently have a 32 gallon Biocube stocked with 4 fish and I am planning on transferring these fish into the new tank.

    Water testing apprehension

    I know I ALWAYS have a little ‘test anxiety’ when performing my water tests every week (alk every other day). I always hope everything turns out well and it usually does. Problem is, when it doesn’t (or I have missed a few weeks of testing), it can sometimes bring on a little panic as the...

    Will chaeto drop nitrate and phosphate to zero?

    I have been consistently getting 0 on Nitrate and Phosphate. I have chaeto in a back chamber that’s literally doubling in size in about a weeks time. I give it 18 hours of light which I’d read was recommended. I also have green hair algae forming on the sand. As of yesterday, my ammonia level...

    Top Three Parameters

    Today I came across a YouTube video... I know,I know, don’t trust YouTube vids. And that is why I’m here asking. The video claimed you really only need to test Temp, Salinity, and PH. What are your opinions on the top, or most important parameters to test?

    Maximum nitrate levels

    What is the maximum nitrate reading you know of where corals were kept successfully? What is the “breaking point” for the hardiest of corals? What corals are the most tolerant to high nitrates? Please input especially if you have large predatory fish! Thanks!
