Paul's 70 TEC v2.0

I'm having Bryopsis problems with my tank. After trying to beat it for about a year I decided to start over. I ordered some new Marco rock and went to town. I removed all the existing live rock which contained bryopsis and replaced it with new. I also decided to try out a deep sand bed this time around. The tank is deep so I didn't mind taking up the extra room. If this goes well it will be time to get some corals again. Let me know what you think. I am also thinking about replacing my 2 mag 7 pumps, one for the skimmer and one for the return with a single pump but not sure which to go with.

I used to use Kent M magneisum to fight bryopsis.

Raise Magnesium over 1500 with the Kent M and keep it there. That along with spraying hydrogen peroxide on the live rock taken out of tank.
 
Just replacing rock doesn't normally work since the algae is already in the tank. Unless you tossed everything and sterilized the tank, it will most likely come back even with the new rock. I killed off my bryopsis using Flux RX. Worked great. Was gone within 2 weeks. I did two treatments just to be safe. It also killed off all my GHA which was a great added benefit.

I agree with this, but if you don't see it now maybe try and get some emerald crabs or lettuce slugs to try and naturally control it. I somehow got bryopsis in my system but it only survives in the refugium. I manually remove it and am getting some urchins, turbo snails, emerald crabs and a lawnmower blenny for the refugium to help control it. While all those critters can eat bryopsis, it can be inconsistent and will vary depending on the individual. I've personally had luck with those and besides the blenny, thats all that is keeping it out of my display. I'm convinced my foxface and tangs eat it, they're ravenous.
