dino question

[Wiz]

Ok so I had dinos a while ago. No doubt it was dinos. Took months and great pains to be rid of it.
My tank ran for months without seeing it. Then I installed my 30 gal dsb fuge. I bought 80lbs of oolitic sand and transfered about 2" of sand from my sump fuge for a top layer. Shortly after I started to see brown streemers and air bubbles off of my macros. Super scared I cut out any algae that showed this imediatly. After 4-5 days of spot trimming every 30 mins, it stopped.
So a month goes by with no issue. Then I trimmed my algaes. Cut out quite a bit. Shortly after trimming the streemers returned. Same thing. 5 days of frequent spot trimming. :-( this happened every time I cut the algaes. I couldn't figure out why.
Two trimmings ago I cut out 90% of my macros. Only keeping enough of each type to grow them back out. Its been about two months and two trimmings since then and no sign of streemers.
So the question, do you think its possable for dinos to sit dormant in sand or in a reef and then cone out all of a sudden? Do you think agitating the algae it lies in can cause it to grow when it has not been? What is your assesment of this situation?
When the streemers came in, they grew off the ends of macros. Especially the chaeto. But all of them. It would grow new streemers in 5-10 mins after I clipped it out. They had the telltale bubbles. And it dId not grow in matts. Only streemers off the macros. defanitly seemed like dinos not slime. I've had both. But beng a bacteria, how could it only grow when I clipped the algaes back? Confusing

yes I fully agree they can stay dormant in sand as a colony and then express when conditions arise. Russ might agree
the only helpful takeaway I can discern from that fact is that we should be trying to bring them out into activity, not keeping them suppressed as crazy as that sounds. stir the sandbed. let some nutrients spike a tad, try to get them out in the open to be killed and warred with accordingly. id keep trying to get them to express and then if they don't for 6 mos I might feel better.

they are obligate hitchhikers, dinos can not be made present in my tank even if someone dosed freshwater planted tank ferts into my tank, and that means something. it means when truly eradicated they cannot come back unless reimported, so this invader may be mean but theres a light at the end
