Anyone see Vittle Vaults leaching phosphates?

[MrSquid]

I've been using two Vittle Vault Outback 80's on my mix station and after having been fighting hair algae in my tank for a while, tonight I tested my RODI line, my RODI container and my mix container using my Hanna phosphate checker. Has anyone else used the Vittle Vaults and seen them leach phosphates? (they aren't 100% sealed - there are holes up top for cords & the hose from my ATO pump)

RODI line = 0.0
RODI container = 0.08
Mix container = 0.11
Aquarium = 0.17 (it was 0.09 last weekend, then I did 2 water changes throughout the week - the 0.17 is what made me test the mix station containers)

My setup is only 35g and the vaults were perfect sizes because of the small footprint & large opening for adding salt - I need something vertical I could replace them with something like this, but I'm hesitant since like the Vittle Vaults, these too are food grade HDPE, so I may not be any further ahead.

Look for NSF - food grade material.

The vaults are FDA food grade. Is there a difference between that and NSF?

I found 10g Brutes on Amazon. I'll probably just play it safe and go that route.

Yeah that's where I'm confused. The vaults say they are good grade HDPE.

Regardless of the how/why, they seem to be leaching.

Brutes are NSF, so fortunately they'll fit for me.

Yeah, all plastic are made HDPE, but NSF certifies food SAFE. Only thing I use for my tank and restaurants.

Your safe with anything NSF.
Did you try looking at tractor or boat supply? Water storage tanks are NSF.

Oh. I just saw you found the brutes.
Good luck
