240G Upgrade

Yeah dinos are a real pain and it is amazing how fast they can overgrow a coral in such a short time.
 
So despite increasing my peroxide, keeping the lighting period very low, keeping feedings to a minimum, changing filter socks daily and not changing water, the dinos are steadily increasing. I'm thinking another 3 day blackout period might be in order. My corals and fish are already stressed a lot, but I'm just not sure what else to do. My nitrates are starting to creep up, but still very minimal.
 
So I decided to start my tank black out on Mar. 20/15, and do it until Mar. 24/15. I also upped my peroxide dosing to 400ml on Mar.22/15, then 450ml today. Tomorrow, I'm going to stop peroxide and start dosing Bioptim and BioDigest to see if that works.
 
Have you measured silicates in your water? If they really are dino's that you're seeing, they make their tests by absorbing dissolved silica from the water. Silica can come from your aquarium's glass for a short initial period, from your substrate if you went cheap and got silica sand instead of aragonite sand, or from your replacement water if you're not properly monitoring your sediment filter on the RO/DI unit.

No, I haven't measured silicate. I'll see if I can't find a test kit for that. My sand was all aragonite.
 
So I got impatient yesterday afternoon and took the cover off after about 75 hours of blackness. No Dinos showed up yesterday and none has showed up today. This is the longest stretch I haven't seen it since I first figured out what it is. I started dosing the Bioptim and BioDigest today and stopped the peroxide treatment. I'm going to keep feedings down, light period down and white light very low and hope it doesn't come back.
 
Updated photo's with the lights on low.

I know someone who has a radion that is mounted at 18in above the water line and he has the intensity set to 90%. What intensity are you running? You should be fine if they are set around there. Also since the tank is 24in deep, you are asking the radion to penetrate 48 in to the sand bed..may be a little much..but PAR meter would be nice.

I lowered my Radions to about 13 inches above the water surface and have intensity at 100%. 1 of my Radions malfunctioned though so I am waiting for parts to arrive as it is on warranty.
