Salt creep?

[MarkW19]

Will SG go down over time due to salt creep?

If so, I have a 35 gallon tank - what can I do to combat the lowering of SG due to salt creep?

It probably would, but regular water changes can help eliminate the problem

are you running any air stones?? make sure there is no splashing or bubbles in the water that will slow/stop the salt creep

 

[Atari]

Unless you only do water changes once every 6 months I doubt it's anything to worry about. Just make sure you're using a refractometer so that your water for changes has the correct sg. An inaccurate hydrometer could possibly make this an issue if it's giving you false high readings.

Like Atari said, just watch the SG with a refractomoter and if it goes down a bit top off with SW not fresh. But salt cannot creep that fast. If you let the salt build up too much, it can break off and cause problems by dropping large crystals into the water.
