I’ve ordered some to dose my mixed reef 180g as I have a really bad crysophyte issue that a buddy told me pp fixed. I do have a dragonette pair though. Do I risk starving them by killing off all the pods or with a full 180g mature system the pod population should still survive?
Peroxide vs algae is a bust...MANY threads on it here and elsewhere. Success rate is similar to doing nothing...some blooms just die out.
You need to determine what caused the bloom if possible, then remedy that situation.
At the same time you ought to be removing as much algae by hand or by syphon as you are able to.
Finally, make sure your cleanup cew receives an upgrade.
The one thing peroxide can work for is spot treating algae, but you need a whole different approach for that. (i actually have a thread for that if you wanna look it up)
