I think I’m going to add some more sand to mine. Do I risk kicking off a N cycle when I do this?
Nope. I do recommend rinsing as there's little lost benefit to an existing tank other than clouding and otherwise mucking everything up.

Heads up, I tried to not sift my 1-2" sand bed for almost 2 years. A couple weeks ago I decided to actually hit some dead spots. About a week later I had a Velvet outbreak. Come to learn from a fish disease expert that velvet cysts (or tomont stage) go dormant and can live in low oxygen areas of your tank like sand for a year or more. Currently, My tank is now fallow, I was able to save a dozen fish, and he recommended sifting all sand under my rock work to stir up any more velvet tomont cysts and start my fallow stage then. I only mention this because of the sand discussion. I only have 1-2" sand in my tank.

This is what I have seen and heard discussed regarding sand beds:
1. They trap all sorts of garbage
2. Need to be vacuumed regularly
3. Are required for certain wrasses who bury themselves when scared or at night
4. Depending on flow and grain size can be a pain to keep how you intended
5. You could go without just make sure your rock work is stable enough
6. I am sure everyone will agree and disagree with my thoughts (flame on)

Here's a topic we never talk about, Sand Depth.......NOT!! Well things changes, people change, ideas change so let's talk about it some more today! I personally love the look of sand. But how much is too much and how little is too little or does it even matter? Let's discuss!

1. How many inches of sand do you have in your reef aquarium?

2. Is there a reason that you chose the depth of sand that you did?

Tomont is a funny word.


On the subject of inches, I started with 2" but aggressively syphoned it the first year and closer to 1.5" now. I stopped with the heavy sifting and syphoning and I ended up (not saying its the root cause) having an issue with nutrient decay. I started stirring up my sand bed with a backend of a toothbrush for about 2 minutes a day and things have greatly improved in the tank(though other changes could have been a factor as well)

I feel like one of the coolest substrates is a fine Oolitic aragonite, followed by a bacteria infused fine white sand "some recommend against buy wet sand" but I like it. Then you top it with a cap of course aragonite, I suppose it would cost an arm and a leg but my idea is that the different substrates promote unique environments for a bigger variety of colonizing bacteria and even multicellular life, diversifying your tank and increasing overall stability.

I got about 2in of sand most spots but I can see under almost all the rocks little holes and caverns where my Pistol shrimp has made, he always gets mad whenever the watchman goby starts moving sand around I’ve seen him stare at him and go back and forth moving sand to each other’s dens

I have around an inch and a half to two inches. I intended to have 1”, but I got a 20 pound bag for my 15 gallon tank and didn’t want to waste half of it, so I put as much as I could that looked nice. 1” was a little skimpy looking IMO.

Back in the hobby after 6 years and went with 2 inches. I like the look, plus I plan to get a goby and shrimp pair
Oh yeah! That was me too a little over a year ago. Was getting back into the hobby had plans for a goby pair and put in my sand. Over the next 6 months I had 3 gobys jump ship before I called it quits and wouldn't kill anymore. best laid plans lol
