Your first problem is your CC substrate. These are also know as Nitrate Factories. Crushed coral makes for a lousy substrate. First it's very hard for your cleanup crew to get between them to clean it up. Second, because of this you will start to get nitrate buildup due to this.
Well, you should try to remove this in the near future or you will have nothing but trouble with it.
Okay, for now you will have to be very diligent and vacume as much as you can. You can't be moving all of your LR
every time you vacume and that's where the problem lays. with Aragonite sand your CUC can get under and between those rocks and clean them out for you.....You see where the problem lays.
I would vacume the best that you can without moving your LR
and try to remove the CC and replace it with the Aragonite sand in the near future.
Are you going to be using RO
To the container of RO
water mix in your salt, stir and get it as close to 1.025 SG
as you can. Use a power head to mix the water. Add a small heater to get the water up to the temp. of your DT. Let this stir and mix over night. Measure SG
again and add more water if it's Higher then 1.025 or add more salt if it's below that.
Do your syphoning out of water and crud and replace with the water you made up the night before.
I hope you have a Refractometer or at least for now a Hydrometer...
