I would like to talk to Randy Holmes-farley about beach sand

Hi all, I know there's a bunch of threads about using beach sand in a reef aquarium, but I bet there aren't any threads directly asking Randy Holmes-farley about beach sand in a reef aquarium!
Hi Doc, I just read a great article regarding silicate in a reef aquarium that you wrote back in '03. I Googled your name and here I am :)
I don't have a reef aquarium yet, but I hope to one day. Right now I'm putting together a 90gal marine aquarium, with the hopes of turning into a reef tank eventually.
I live on the tip of Cape Cod and have already decided to try using water on the ocean side. What I'd also like to do, is have a 4-6" deep sand bed using beach sand. Most people tell me I can't, but I'm not getting a satisfying answer as to why. For that matter, I also have a lot of people tell me I can't use ocean water, but I'm not listening to them anymore. I've made up my mind to try it anyway!

So Dr Holmes-farley I ask you, if I do a deep sand bed with beautiful (sterilized) cape cod beach sand, will I be able to do a reef aquarium?

Feel free to give me a 30 page answer, and thanks!
 
Hi accord, I'm waiting for the definitive answer from the park scientists, but I'd wager on it being 90% quartz. But I see Randy Holmes-farley lives in Massachusetts, so I bet he can answer that too lol
 
Hi albano, I just grabbed the sand a little while ago. I grabbed it from the beach and have it sitting in water in the buckets. I plan on rinsing and soaking it until the water is clear. Then I'm either going to boil or bake it. The sand is sugar sized. Thanks!
 
I'm no expert, but I would think that beach sand is the worst/dirtiest of all sand...probably better to collect as far out as possible

There are plenty of people that use ocean water, but I believe that it is collected a few miles out from land.
 
In general beach sand and water collected close to shore has the possibility of the most contaminates/toxins/nasties,etc... in it..
Could your beach sand/water be fine.. yes it could..
Could it cause problems.. yes it absolutely could..

The risk is yours to take...
I doubt Randy is going to bust out his chemistry set and go check it for you. :)
 
Ha mcgyvr! I wouldn't mind him breaking out his chemistry set on my water and sand, but I was more interested in how a reef aquarium, or even just a marine aquarium, would handle a deep beach sand bed.
Everyone I ask or talk to has an opinion. Most of the opinions are based on opinions. I'm just trying to get an answer from someone who can give me an answer based on science. I read a couple of articles/papers written by the good doctor, and figured he might be the most qualified to answer my question. I'm also waiting to hear back from WHOI and the scientists from the National seashore lol
 
if you want an answer based on chemistry get some test kits and a ten gallon tank and some dry rock. set up a tank and see what happens. Randy-Homes beach sand is going to be different then your sand.

Actually he might have a halfway decent idea about the makeup of the beaches around me. But I'm more interested in if it's possible to have a functioning deep sand bed with sand that's made up of mostly quartz in a reef aquarium. As opposed to a substrate made up of crushed coral/sand. He wrote a very interesting paper/article about silicate in reef aquariums and that's why I wanted to ask him. I had someone tell me earlier that some of his crabs died because he used beach sand (silicate) and his crabs needed coral. I've also been told that the beneficial bacteria needed in a reef aquarium won't live in beach sand. And I've had others tell me it's fine.
 
It sounds like you're pretty set on doing what you want to do, so why ask if you can? Give it a shot - what's the worst that can happen?

You also seem to have an odd infatuation with this Dr Holmes-farley fellow...
 
Glad Paul B's tank was mentioned.

The majority of people like to point out how "contaminated," "dirty," and "dangerous" collecting your own reef organisms is. But then there is Paul B. He's quick to point out that he has no degrees, and doesn't consider himself an expert, but his tank and method speaks for itself. He's a pretty big believer in adding stuff from the "wild" into his tank. The number of fish that have successfully spawned in his tank, and the longevity of his livestock say that adding stuff from the ocean aren't nearly as dangerous as some would have you believe. His tank will be 45 years old next year. Good luck finding anyone else on RC, or in the hobby, with that much experience.

Regarding your question, there shouldn't be any harm in it. While it's probably quartz based sand instead of the aragonite commonly used in the hobby, it'll work just fine. Again, some will say that you'll have silicate problems, some will mention the lack of life in the sandbed because of the sharp sand grain edges present with this type of sand, others have had success with it.

I say go for it. There's no absolute reason why you can't.

According to his first couple posts and pics on that thread...he has dolomite as a substrate, not beach sand
