so i'm doing my first water change but i added cured live rock so there wasn't an ammonia spike, my nitrates are still pretty low. all i have in my 65 gallons so far is about 40lbs lr 2 damsels and 5 astrea snails. i have my salt water mixed in a bucket and i'm guessing i should wait about 24 hours to be safe? my question is do i have to siphon out the substrate aswell? my substrate is pretty fine so im worried it's gonna siphon some of it out. it's the caribsea brand. should i just leave the sand alone?

OncE in a blue moon I vaccuum the sand and if your running a sump you will have to turn it off

Salt mixes up right away. Some people like to wait a period of time to let things settle but personally, I take a bucket, fill it water, add salt and then dump a powerhead and heater into the bucket and let it sit while I'm at work. I do this so the water comes up to temperature; no other reason.

You can leave all your pumps and powerheads going depending on where they are. Let's say you're doing 5 gallon change; when you sipho-off 5 gallons, does the water level go the level of the pump intake (or close to it) ? If so, turn everything off.

When you add your new water, if you pour it from a bucket, it will stir-up every piece of sediment in your tank. What I do is dump a powerhead into the bucket of new water and put a length of tubing on it and pump the water back into the tank, being careful to aim the hose at the tank wall. When it gets close to the bottom, I remove the pump and gently pour the remainder in.

You'll develop a system. Spend some time getting it to work with a minimum of effort because regular water changes are important and the easier (and faster) they are, the more likely you are to do them.

good idea about using the pump to pump the water back in. i was trying to siphon it but since it was so low, as well as my sump, the pressure was crappy. i got fed up and used a bucket to scoop it out... lol
