ok, can sombeody explain why I get salt creep around my hood, fixture, overflows etc... But, you never see salt creep around pier pylons, seawalls, buildings or rocks that are near or in natural seawater?
I think yeah rain has something to do with it (have you ever thought who Does the Top-offs in the Ocean?).
But i think, it mostly has to do with the fact the the Ocean is Huge and it works like a well oiled Machine and that's why we don't see salt creep. There's no HOB on the middle of the Ocean or a Skimmer.
Saltcreep accumulates when water splasing occurs ON a surface and it sits Still & it's followed by touch of air. Which usually happends Out of water.
When you go to the Ocean and look around the rocks or ports or buildings, You never see Saltcreep, you see green algea which is because those areas are polluted or stagnant or both.
Because the ocean has waves that constantly wet the surrounding area. The ocean also does not have walls like our tanks do. Also the water level in the ocean goes up and down every day, the tide comes in and the tide goes out.
Simply rain and/or dew. No way is it because the wind blows it away, the wind can blow on shore too. Who does the oceans top-offs? Remember in grade school, they taught us that the rain collect in the ground and runs through underground aquifers and also into all the tributaries which lead to big rivers which make there way down the ocean, here the mississppi is the largest "drainer" of the USA. Its fresh water(but not clean imo), so it would be considered "top-off" lol
In general I would say that our tanks are not exactly approximations of the ocean...these environments have tidal changes, rainwater, etc that don't let areas dry out a lot.
But if you compare it to a more similar environment, such as a hypersaline lake where "top off" is limited...you have a lot of evaporation, no tidal impact to redissolve salts, and so salt crusts will form around the margins.
i work in construction on lbi in new jersey everything is covered by salt from docks to cars and houses, variations in tide heights tend to keep large build up on things like bulkheads and pilings
my friend has a fishing boat and when they take their boat out for winter there is some salt that is on it that they just hose off with fresh water. some saltlakes have large areas of salt flats where the water has receeded and just leaves salt.
