nothing has changed in the last 4-5 years apart from the skimmer. i use prime
just salt and i test the first batch and adjust the ca/alk / mg as needed. i roll the bucket first to mix it up, same chems Ive been using for years. last time I ordered a batch was probably a year ago but i use them in my dosing and nothing is out of wack. 55Gal plastic drum Ive had for 6-8 years, clean it out id say every 6 months.
my vertex in180 never had this issue. im just dumbfounded what would cause this. the skimmer neck is also clean.

it runs just fine for weeks i shut it off do a WC and 15-20 min later it wont stop overflowing

i usually do a WC fill up the mixing bucket and have the salt mixing until i do another change and turn the heater on the day or 2 before and exactly match the SG

Prime will do it. I have used Prime exactly twice and both times my skimmer went nuts for a couple days. Try your next change without and my guess is you will not have that problem.

Sorry to Hijack, I have been thinking about switching to tap water...have never used anything but ro/di and want to see for myself how tap water is actually different.

Myka, is there a particular dechlorinator you would recco?

Usually the prime is put in the mixing bucket and that's 2 weeks before it goes into the tank. The vertex in180 never did this.
I'll try tho and report back.

As far as I know, our lower mainland water is only treated with chlorine, a gas that dissipates out of the water all by itself, or faster with an airstone.
Someone a while back posted that the LM does not use chloramines.

I have never used prime as I always mix my water days in advance.
