Can’t kill these dinos

[telsonman]

So I figured out a while ago that I had dinos I’m my frag tank. I did a 50% water change, twice. And did a three day blackout. Then did a peroxide dip of the frags before placing them in th clean water. I ran a UV skimmer as well. I didn’t see anything for a few weeks, nor did I add anything. Low and behold. They came back. I’ve been dosing peroxide at a rate of approximately 3-4ml/10 gallons. This is a 60 gallon tank. This still does nothing. I’m about to use Dino-x I guess, and if that doesn’t work then I’m just going to drain, scrub, and start over. I really don’t want to get there.

As far as the strings of the dinos go, they are really only on the egg crate. The frags all seem to have a fuzz that covers them, and it will snuff out my zoas. It grows around my mushrooms and SPS. Still on the plugs though. I’m attaching some pics of what it looks like on the frag plugs.

Any ideas would be appreciated. Parameters are all good, and I’m skimming quite a bit. My filter socks are getting clogged in about three days. I’m scrubbing frags off every other day, that’s how fast it grows.

#Chrysophytes @reeferfoxx ?

This is what they look like under a microscope

are you dosing vinegar/vodka ?or any other chemical to lower No3 ?

 

[telsonman]

No. I only run a skimmer and a dual reactor with GFO and carbon. I actually have to dose nitrates every now and then, and try to keep it around 1ppm. Phosphates stay around .02-.04. Alk at 8.5. I only have a damsel and a really small lightning maroon in there, and a couple crabs. Not much livestock except corals.

 

[wattson]

how old is your tank?
did you use live rock or dry to start this tank ?

 

[mcarroll]

Big cells dino.

Little cells chrysophyte.

Love to get another opinion on the chrysophytes...but from the macro and micro look I'm guessing that. Also on the behovior of snuffing out corals. Chrysophytes seem to go nuts on the mucilage generation and it seems to give them superiority.

Post on the dino thread linked earier to get the dino's ID'd more specifically.

#Chrysophytes @reeferfoxx ?

The problem/no problem about chrysos is they take a 2500x microscope to ID but are real easy to get rid of. With past experience, it's wiser to rid the tank of dinos before chrysos.

FWIW they look like ostreopsis. They have the sesame seed shape. I could be wrong.

What worked for me in both my frag tank and 180 display was based on what I learned from reading the thread referenced above by g5flier. There's a lot of good information there! My process: I manually siphoned dinos using rigid tubing (same as used on RODI hookups). I would do this with all flow off. Replaced all siphoned water with fresh water. Ran socks and changed frequently. I raised phosphates and nitrates more into the 0.05 and 5 region using neophos and flourish nitrogen. I added a lot of pods, and started dosing phyto. Took about 4 weeks to clear up. I would do the siphon weekly during this time. The display tank then got a huge cyano outbreak. I used chemiclean and about 2-3 weeks later the dinos came back. I repeated the dino procedure above and the tank has been clear for 6 weeks now.

Definetly chrysophyta on the plugs.

 

[telsonman]

What’s the best way to get rid of chrysophytes?

 

[mcarroll]

Manual removal as-needed to keep corals safe while you're dealing with dinos. Check out old threads on the #chrysophytes tag and @reeferfoxx's chrysophyte thread. They may even give up while you're clearing up the dino's.

 

[reeferfoxx]

Yeah the focus is clearing dinos first. The last reefer in the same situation decided to go the chrysos route instead. It created a sand storm of other issues.
