I have heard of people using a little bit of a commercial product called Salt-Away in rinse water to thoroughly remove ocean mineral residue and prevent that whitish buildup on camera housings. The effective ingredient is sulfamic acid, which is sold as a cleaner at places like Home Depot. When sufficiently diluted it is safe, non-toxic, harmless. The Salt-Away label says it is effective even at 1:500 proportions. I'm taking a trip soon with a Kraken rinse bag so I'll have a chance to try it on just my own gear when rinse and soak options are limited. To save weight and space I might take the crystal version instead of liquid Salt-Away. An old film canister full would probably last me the whole two weeks. Four ounces of the 99% reagent version is about $12. Has anyone here used it? Here's the wikipedia entry: https://en.wikipedia.org/wiki/Sulfamic_acid

Greetings, all, I’ve been taking photos underwater for some time, with a Nikon D300, then D850, and very recently a Nikon Z8 with Nauticam housing and Ikelite DS230 strobes. The only video I shoot is with a DJI Action 5 on top of the housing. I enjoy it all from supermacro to CFWA. On my next trip I'll be using the WACP with the Z8 and 24-50 lens, but I miss the range of the WACP with the 28-70 lens on the D850. I'm irrationally optimistic that the new Z 24-70 f2.8 II will work with 60-70mm of extension. I have land and UW shots on IG: https://www.instagram.com/rickfrancis.photos/
