So, my diatoms are seriously less than they were. I got 30 turbo snails and 20 cerith to try to help clean up all the junk. It’s helping tremendously. I got a conch for the sand bed. Just love those things. They’re very efficient. I still don’t totally understand the radions so I’m renting a par meter tomorrow to see if I have them on too high or not high enough. My zoas aren’t real happy, but everything else seems to be. I added a second DI resin filter to my RODI and am happy, embarrassed, excited to say this is the first time ever I’ve had zero TDS. LOL. I tested my water today and all checked out good except calcium. It’s 320. [emoji37]. I used Hanna, Red Sea, and API. All were with in a couple hundredths of each other on all parameters. I’m not building a watch here, so I’m gonna stick with api for awhile bc I’m lazy when it comes to testing and they’re easy. I’m also happy to report to Ty, that when I added the po4 reactant to my sample it didn’t turn blue!!!!!!! [emoji122][emoji122][emoji122]. My po4 was .22. Also lowest it’s ever been. Lol. Will bring it down a bit more, but excited about that. I’m going to begin kalk in my ATO when it arrives from BRS. That’s the best route for me. I have the 2-part and dosers, but think I’d like the simplicity of the kalk better. Sent from my iPhone using Tapatalk
