Cyno after moving a tank

I know there is like a million Red Cyno threads but i just cant figure this out.
I moved my 40gal breeder to a new place about a month in a half ago and have been having some super bad cyno issues. So i thought id post up some things that i changed around after the move because of spacing issues and general convenience.
I removed all the tank water and discarded it. I had the access to all new mixed saltwater to fill the tank back up. I removed all the sand and and rinsed it. The live rock was all moved in tank water and wet newspaper. I set the tank back up in a very fast manor.
There are a few things that i changed when getting the tank back up and runnin. I am wondering if any of them are causing some extra nutrients in my water.
1. I changed my ato water reservoir from a large clear rubbermaid to a small tall, and narrow storage container.
2. My ceiling is now higher at my new place, so i had to hang my radion a lot higher than normal. Its around 19" off the surface of the water which is about 2 times as high as Ecotech recommends.
3. I got a new stand during the move and the stand is shorter than the old one. This is causing my Calfo/coast to coast overflow standpipes to fall a little further under the water line in my sump. They are not quieting down and there quite a bit of bubbles coming into my sump.
4. I lost my sand sifting Diamond Goby after the move and he kept my sand really clean.
5. I rinsed out my refugium pretty well with the move.
6. I added a piece of live rock w/polyps to my sump from another one of my tanks.

There are some things i have done to eradicate this cyno.
1. Started feeding less.
2. Increased the flow in my tank.
3. Tried to skim more wet.

Thats all i can think of at this time but i will think of more soon. Im really curious as to if any of these changes or a combination of them has contributed to this issue?

 

I'd attribute it to disturbing/rinsing the sand bed. You may have been better off to use new sand as opposed to re-use the old.

 

Rinsing with tap water , did you allow it to dry?

 

Oh. That would of been kinda expensive and I washed to sand pretty good in the old tank water I removed.

 

I rinsed it with the old tank water I removed. I couldnt let it dry, I was moving it. Had to move fast

 

Rinsing sand/ new water/moving LR prob caused a lot of good bacteria die off. I bet if you get Dr Tim's waste away bacteria, it will take care of your cyano very quickly and naturally. Very cheap and effective way IMO.
