Such a good concept but they just don’t work

Most of the Rola-Chem installs on KZbin show the system components mounted outdoors but the literature says "Install the ROLA-CHEM® pump in an area protected from natural elements (sun, rain, freezing, etc.)." Apparently outdoors installations are standard?

What if the pH is only calibrating between 6.0-6.9?

Are you diluting the acid tank with water or just adding muriatic acid out of the bottles? I’m hand dosing about 8oz a day of Kemtec muriatic acid 34.5%. I am dosing liquid chlorine with a Rola-chem 12 gpd pump but want to feed muriatic acid now also. Of course I will set a timer switch so they don’t dose at the same time. I’m not quite ready for the ready to mount system yet.

When dosing with muriatic acid, for lowering the PH, are you adding/diluting with water the holding tank or just putting in the acid out of bottles? I’m using a 5 gallon Rola-Chem tank and would be adding just 2 gallons. I don’t want to add anymore since I’m only needing to dose at about 8oz a day of Kemtec 34.5%

How about some videos for us pool pros to send clients on what a rola-chem is and what the benefits are?

works great in my above ground pool. Gets everything including leaves off the bottom of my pool. I love it. I just ordered a new one after 2 years of use on the old one.

So what is really Does? Fills up the pool?

LEAVES GUYS, WERE AFTER LEAVES! - A TABLESPOON OF PEPPLES IS HARDLY A GAME CHANGER

MUSIC over the demonstration? How stupid?

Fast review 👍

big UP. One Day Everyone will love all! Can we be youtube friends? xD

Need some detailed installation videos using updated panels with relays. How to install roller with pump turn on and off. Would like to see a schematic at least. A way to purchase through your website would be nice.

Great concept. I am a little more picky about filtration. I replaced the 2 screens and filter with two parts that were 50 cents and it works amazing (Engineer by trade).

Great information.

so is the 300 series waterproof or something? what is the differences?

Muy Bueno!!!

good video, losing the music wouldn't be a bad idea!

Hi i work in a swimming pool shop in Auckland , Nz . At the moment we are desperately trying to source information for an older rolachem digital controller (RC-257) we are trying to source a manual that will help us re-calibrate the ph sensor , can you help at all?

one question. #1 if is it OFF - Orp will feed even though ph is out of rage? correct?
