Tri color valida

So, I had another idea to use the Hanna Phosphorus Ultra Low Range Colorimeter for a different purpose than it was intended for. This time, I wanted to see if my water has a yellow pigment. I started with a vile of saltwater using RO/DI water then testing it against a vile from the tank. My...

So, I have this idea to use my Hanna checker to check the color of my Nyos Nitrate test kit. I was wondering if someone can save me a water sample at the same time you take one to send to Triton. I'll get a number from my Hanna checkers, I can use both my Alk and Ultra Low Phosphorus checkers...

So, I had this idea to use my Hanna Ultra Low Phosphorus Checker to see the color difference of my Nyos Nitrate kit. I don't even register 1 with my Nyos kit but it shows 14 with the Hanna ULP Checker. I'm assuming that I'll be able to track slight variations in nitrates using the Nyos liquid...

Last Saturday, I posted to a Reefwise thread that I picked up an awesome gold acro frag. I went through my usual routine of acclimating it then inspecting it with a jeweler's loupe to look for bite marks, hitchhikers or eggs. So far so good, everything was good. I then made my favorite...

There has been a lot of talk recently about an alk continuous test device that Neptune bought the rights of. It looks like CoralVue may get the jump on them and theirs also doses alk. CoralVue to Distribute KH Guardian

My tank was running for something like 11 years. It was originally set up old school, a rock wall that that tappered from top to bottom. The top corals ended up shading everything below so things stopped growing low anyway and I hated all those mushrooms. I went form this: and this: To...

I remember the first time I saw one. It was back in Menard's store, ReefDweller, Reef Dweller's, in the early 2000's. I set a small one up once but it was pretty noisy. Does anyone still run one? What are your thoughts? I'm thinking of trying it again but insulating it for sound.
