Are all plastics safe in teh reef?

[EpicWin]

So i made a skimmer stand using a silverware basket I found at lowes... It is not food grade or anything like that just black plastic. I also had to silicone around the plug of my skimmer pump because it had come loose... I used reef safe silicone (rtv 108) and let it dry a week out side tank... today i came home and foudns ome sps that had previously been doing great STN... im in need of some serious advice. The tank has been super stable for months so the issues pretty much can be narrowed either to teh new skimmer or the stand..

Only plastic that is BPA free should be used.

Any plastic that has recycling numbers other than 1,2,4,5,&some 7s are bad if I can remember correctly. I do know that 2 is the best. There should be a stamp on the plastic with a number inside a triangle. All of this info is on the Internet.

If using an unknown plastic i wouldnt use any for ref tank that doesnt have the NSF tag. Means its food safe and wont leach chemicals

Do we all agree that egg crate is totally safe?

For sure it should be as much as its used. I think it gets used in aquariums.more.than a light difuser

Some egg crates will leach phosphate. I do not use it anymore but was told if you give it a vinegar bath it will be ok.

If you can find acrylic egg crate that is preferred over polystyrene egg crate.

I actually prefer acrylic racks like The Blue Glow makes.

What about lighting diffuser is it definitely reef safe?

Im not convinced it is the skimmer or the plastic. that seems like a chemistry issue to me based on what are you seeing. double check params and params swings is my thoughts

It turns out it was a gfo issue. I added gfo and things went bad

Guessing you probably.used the recomended ammount? Thats way to much and striped your tank to clean. BRS GFO needs to change the ammounts this happens all the time. I see many posts about the same thing.

Yep I used a little more the. The recomended because it says 2x dose is ok.
