Hey guys! I just wanted to share my excitement with you all and maybe help someone else down the road
!
I currently have a 60’ish total water volume (3'x2'x20") and for the last 4+ months, I have been dealing with Dino’s.

At first, I didn’t realize it was Dino’s and did 4 or 5 consecutive 20g water changes hoping it would go away. It didn’t.

I probably should have went the route of identifying which Dino’s I had with a microscope but, I ended up adding a 36 watt UV sterilizer. The Dino’s I had did not disappear at night like most people online said there Dinos did but, I tried UV anyway. This ultimately did nothing.

I then researched a lot more and decided to raise my nutrients and dose bacteria. I was really patient with this and figured that my tank only being 9 months old, maybe it was a maturity thing.
Raising my nutrients didn’t do much other than bringing on a bunch of hair algae. Based on a Salifert test kit, my nitrates were around 50. For some reason I was having a hard time raising my phosphates but, the last time I tested with a Hanna checker, they were around .06.

I even tried changing my filter pad every morning and syphoning the sand bed a couple times a week but in the end, they just returned the next day.

Finally, I decided to do a black out. Not only did I turn my lights off entirely, I cut out card board and completely covered the glass.

I gave it a little over 3 days without touching the tank. The only thing I did was change the filter pad on day 2. I left everything running including my skimmer and UV.
Today I came home, took the cardboard off and EVERYTHING IS GONE!!!
Dinos are nowhere to be found and the green hair algae is gone as well! The few corals that I currently have don't seem to be bothered other than a little loss of color. The fish even seemed happy and excited to have the light back, swimming back and forth enjoying life.

I don't think I've seen my sandbed this clean since I started the tank up!

I turned my lights back on to only 20% with a 60 day ramp up and then did a 20g water change to lower nutrients (although I haven't bothered to test just yet) but, will do in the next day or two.
Since it's only been an hour since the water change, I don't know if the Dino's are gone for good or not but, I will continue my maintenance routine and keep an eye out.
I sure hope that I won this battle and never to have to deal with Dinos again. Only time will tell..
Fingers crossed!

Nice!

Eight month new cycled tank at seven months (month before) diatoms lessened and as well a cerith snail population occurred.
I haven't done a substantial water change yet for my 66 gallon. I daily add distilled water 1 gallon for evaporation and every month or two replace 4-5 gallons with salt when performing canister cleaning. A recent Reef Octopus HOB 2000 Protein Skimmer and six month in use 18 watt CoralVue Twist UV are part of my reef eco system.
I was debating about a sump/fug but at this point everything seems adequate. A sump/fug might present a cleaner rimless display but 40 pounds of live sand and 40 pounds or so of live rock are enough of a fug.

That’s awesome congrats! The blackouts and the UV are the only thing I haven’t tried yet. I feel like I’ve slowed them down by getting my N and P up but they aren’t totally eradicated. If in the next couple weeks they aren’t totally gone I’m gonna give it a shot.

To be honest, I never believed that Black outs worked until I did one. Not just lights out, a complete black out like I did with cardboard..

Yeah that’s exactly what I was planning on doing. I just got my skimmer running so I can feel good about oxygenation with everything all buttoned up, might go for it this weekend.

I've run an UV 18 watt sterilizer 24 hours for months. Now diatoms/algae are at desirable levels I made a slight change implementing a cheap electrical timer outlet from Harbor Freight. UV sterilizer is set to run during the day for 12 hours and off 12 hours throughout a night. A couple of days now my timer was installed and haven't noticed any increase of undesirable diatoms or algae.

Be neat if a "random" light setting could be set more or less recreating natural weather conditions at varying depths including black outs or storms for a few days. There's an idea wifi from whatever weather/forecast broadcast over seas where livestock originated. Might help fishy feel less home sick :)
