Skimmer remove salt?

[novanosis]

Just wondering since a skimmer does remove water, does it also remove salt?

Say skimmer does remove water, can I just add ro as top off?

Or am I suppose to worry about salinity?

Don't worry about the water in the skimmate. It isn't enough to make any difference.

Skimmers do remove salt and if you are hooked up to an auto top off you need to check the salinity often. I test it about every other day. Especially when my skimmer is running overly wet.

i run it dry? but i will take your word for it.

Common question. "Was does it seem my salinity is always low beofore my next WC" Reply: "It is your skimmer. " If anyone has any doubts stick a conductivity meter in it. Organics which are high in skimmate have no charge, thus can not conduct on that meter and add to the reading. Only - or + charged substances have conductivity. It makes no difference if it is dry or wet but wet will have more salt in it. it also depends on how much skimmate you produce / day. Now, if you do weekly WC and adjust for Salinity then it is not much of an issue, especially if the top-of has kalk, which adds to the salinity reading, as Ca(OH)2 ----> Ca++ + 2-OH -

Very interesting. Thank you Boomer.
I wish I knew that BEFORE I did the finger taste test!!

Yah Franky but the finger taste test works great and is done in a second, with no calibration or test tubes
