Numbers are Nitrates 10ppm using salifert and 0 with elos, phosphate .0 salifert and .03 hanna phosphate.
Randy im thinking same thing but if it lowers anything will be a good $20 spent and im thinking may be good media for a quarantine or even to start a new tank off. I was thinking also of running less rock in my 200 build coming soon and thought these could help out. These things are super light and very porous so has plenty surface area. Hey we have spent money on plenty other things thinking they will help so one more thing cant hurt. My tank seems so much happier feeding more but would like to lower nitrate to about 5ppm and would rather it be naturally. The less time I have to spend working on tank the more I enjoy it. The apex was some of the best money I ever spent, can automate about everything and just have to check few times a week instead of dosing manually and all the other stuff too.
