    Dinos showed up while using Chemiclean

    Hi all, I've had my reef tank up for a little over a year and a half. I have learned a lot in that time, specifically that keeping a reef is much more intense than I originally thought coming from the freshwater side of the hobby. Before I decided to jump in to reef keeping, I thought all the...

    I've had my 20 gallon tank (LS/DR/RODI) for around 2 weeks and I've recently started getting brown growth (with stringly bubbles) on the sand and eventually the rocks. When it just appeared, I suspected dinos so I started overfeeding a bit and removed my chemipure blue. My nitrates and...

    Well I’m having a little issue. Seems it has gotten out of hand pretty quick. Can you tell what this is from the pics? I don’t see any air bubbles at all, anywhere. So hoping not Dino’s. Was thinking Cyano but chemiclean isn’t doing anything to it.

    POLL for those who have had DINOS

    Trying to gain some insight into conditions that might point to a trend. I personally have come to think lack of bio diversity and too low of phos and nitrate are the primary conditions that cause dino outbreaks to bloom, but since no one knows for sure, thought I would give this a try. Thanks...

    Dinos on Corals

    Couldn't get a response last week, so gonna ask again... maybe I'll get lucky and find someone who knows, lol. Any advice on how to "clean" a coral from a dino-infested tank before moving to a dino-free tank? You think a peroxide dip would be enough?

    Moving corals from tank with Dinos

    Im going to break down and disinfect my coral QT that has been overtaken with dinos. I need to move my corals to my DT. Besides a good dip in some CoralRx to catch any bugs, are there any other precautions I should take to ensure the dinos dont transfer to my DT? Peroxide solution dip possibly?

    Can Dinos cause really low ORP?

    So after reading Randy's excellent simple version of the guide to ORP, I get that ORP mostly is the battle between oxydizers and reducers. A reducer can be food, waste, dead things and probably a ton of other stuff. Would it be fair to draw a conclusion that Dino's killing microscopic things in...
