Is it safe to use these crates like in the attached picture in our tanks, will it hurt the tank in anyway.
Plastic crates safe?

Can't speak to the plastic, i've used similar items before with no issues. On another note, get rid of those ceramic rings which i'm assuming are intended to be "filter media," much better options out there. Look into sintered glass media.

Most plastic is fine but can't say those for sure. As for the ceramic rings, not a fan of them but while you save the money for good media use those

A good replacement/upgrade to media in those crates. This new media comes in many shapes and sizes. http://www.bulkreefsupply.com/marinepure-ceramic-biomedia-plate.html BRS has a video on rocks/media surface area.

None of you have any idea what your talking about... The media in the crates is Sera Siporax, far and away the best media you can use, way better than anything BRS sells

This is my buddies tank, he and a few others in the area have had good luck with the rings. I have some one order and wanted to make sure I get a container that is safe. I also already have the media blocks as posted above. I think a few varieties we work good.
No need for the insults friend, simple disagreement. I've gotten more mileage out of alternatives, hands down. To each their own.

If the crates are made of polyethylene or polypropylene, they should be fine. Check for a recycling code on the bottom.

missed it thanks. I still would remove media in crates and add more ceramic blocks.
What codes would those be? 1s and 2s?

Does the Block not release aluminum? I thought I read people having issues with them. I will have both just for the variety.
There's a monster thread out there on this very debate. Per triton tests, those using marinepure have shown increased levels of aluminum. I think the debate is really what affect it plays on your livestock. It seemingly has a harsher affect on soft vs stony corals. I would also imagine it depends how much of the stuff you have in relation to your total water volume.

I currently have 4 blocks with about 450 gallons of water.
So I should look for 4 and 5s on the bottom of the crates for best results?

These both have a number 5 on the bottom. So does that mean they are ok to use?
5 is polypropylene, so as randy said, it should be safe.
I dont like the dye, and would be sure to use activated carbon.
Also, id take those handles off, they could be anything else.
