    Is there a dummy's guide to how hydrogen peroxide helps with nuisance algae?

    I used it recently to help fight back against cyano, and I see it being used quite often to help with algae. How does it work? Why does it kill the bad stuff, but the tank seems to be perfectly fine? Why is the good bacteria spared? How is it affecting the inverts? Does it accumulate and need...

    DIY trace solutions - How dilute is too dilute? When should I remake the solutions?

    Hello @Randy Holmes-Farley. You mentioned in a few threads that the less concentrated a solution is, the less stable it is due to air oxidation. I understand that the rate of air oxidation is different for different elements but I don't know how long will my DIY trace solutions last in...

    Spawning/reproduction

    I'm very new to this so this is very far off for me but to me this is the epitome of coral husbandry so everything leads to it. Its the reason I got into the hobby. From what I know, getting coral to spawn/reproduce instead of fragging is few and far between. Ive only personally read about it...

    The Ways Alkalinity can Accumulate in a Reef Tank

    The Ways Alkalinity can Accumulate in a Reef Tank @Miami Reef "Why is my alkalinity rising?" is a seemingly simple question that consistently pops up in the chemistry section of Reef2Reef.

    I currently dose 1mg kno3 and 0.04mg kpho3 weekly but since it's weekly i often forget to do it, sometimes a couple weeks in a row with visible degradation to acro health, so i want to automatically dose it. I only have one channel free on my kamoer dosing pump. Can i mix potassium nitrate and...

    Calcium and ALK levels - are mine ok?

    I’ve been in the reef game for a long time, but took a break for a while and just recently got started again. This time around I’m trying to make sure I really stay on top of water parameters, so I’ve been testing regularly. I started this time with a used tank from my dad, a Red Sea 350 and re...

    Add phosphate with doser then remove it with gfo reactor on timer?

    Is it possible to dose phosphate during the optimal period of the daily photo cycle, based on the best time corals are known to absorb phosphate from the water? Then to keep it from climbing, and reduce the time spent monitoring, remove the phosphate daily, with a GFO reactor on a timer, running...

    NO3 and PO4 chemistry

    I have a question about NO3 and PO4 chemistry. Usually when PO4 drops NO3 would drop with it right? I've been having problems keeping PO4 up, so far I removed pellet reactor and disconnected the refugium. But as soon as I turn the fuge back on the PO4 drops too fast, is it possible that the...

    Is Anyone's Hanna Magnesium Checker Not Reading High?

    I've heard about the problem of Hanna's Magnesium colorimeter reading high and recently learned that you can fill out a form on the Hanna website to get them to send out a new Reagent to correct the issue. But has anyone not had to do this and is getting similar results to other tests they do? I...
