i am looking to identify this algae outbreak I am having.... Nitrates test at 5 ppm (redsea) and phosphates are at .002 ppm (redsea)

I've tried using vibrant reef and it hasn't done much .

Am I dealing with typical GHA or maybe bryopsis? Or is it something else? Any assistance is appreciated.

Predominantly GHA. It appears you have a system that is less than 2 months old (clean bottom beneath rocks and very little coraline algae on rocks).

Vibrant is fine, but no need to go beyond label dosing recommendation. Consider Dr Tim’s one and only and seed with that over a period of 2 months (dose 2x at 1/2 strength).

This tank itself is 3 months old. it was an upgrade from my 30 gal (now 90). When I upgraded I seeded with Seachem Stability using their schedule (7 days). Should I still go the Dr. Tim's route or dose some more with the Stability?

It appears that your system is going back through that 2-4 month “ugly” phase. Since the rock is from an established system and you have already dosed at least one bacterial product (maybe two), I would let the GHA (and potentially coming dinos and cyano) run their course. It could simply be that disturbing the rock as well as having all new surface area in the tank was a big change (disturbance) and all needs to just find the new balance.

What inhabitants, if any, do you have in the system (fish, inverts, algae)?

Is the sump, skimmer and other filtration components new or carry-overs from the 30 gallon system?
 
Yes the sump and skimmer are new as well with the tank upgrade.

The tank has 2 clowns, 3 yellow tail damsels, diamond goby, cleaner shrimp, and a lawnmower blenny that all moved over from the 30. The only new additions are 3 turbo snails.

I was guessing it was a case of the uglies but wanted to make sure it wasn't something else first

I will let it do it's thing then I guess while maintaining nitrate and phosphate levels in acceptable ranges

Sounds like a good plan. I’m sure others will post with additional advice. I anticipate some will suggest bolstering your CUC; and will have some good specific recommendations.

Your lawnmower Blenny may help you with the GHA, but sometimes they just like the food we feed them. You might consider some other larger herbivores. Tangs really did a number on my GHA. A Kole tang should be fine I’m a 90gal. Maybe a Yellow Tang would be okay, maybe the tank is too small for that. Right now, I have 2 yellows and a Kole in my 135Gal and that seems to be the limit for my system.
 
That's exactly what I was thinking too I am keeping my eyes open for a a Kole Tang. My LFS has a nice powder blue right now
 
PBTs are great algae eaters but need about a 6 foot long tank. I had one in my 135Gal and it got very fat. But then it nipped at my goniopora and I had to sell it back to the LFS. Workers actually fought over who would have the rights to buy it. The goniopora eventually died. PBTs sometimes take a liking to LPS corals. I’ve never seen a Kole or yellow tank nip at corals.

I would hold out for that Kole.
 
Thanks for the tip! Kole tangs seem to be hard to come by locally (Ontario)
