Hi there, my name is Bianca. I'm new to this forum and a new spa owner greenhorn. I'm having problems with cleaning. Using the spa or not does not make a difference in the yellow-greenish "bubblegum" lines that appear on the walls on the waterlines (load with 4, 2 or no person).
Please bear with me, I'm not a chemist and don't know the difference between chloride and chlorine in their different forms like granulate, tablets etc.. I only know that I use NaCl in my kitchen
Our spa was delivered 4 weeks ago, completely new. We filled it up, the technician ran some tests, shut the thing down, disconnected the electricity and in the next few days my husband built in a RVS heat exchanger from a secondhand central heating system (gas-driven), and filled the empty spaces between the frame, the tub and the floor plate with extra rockwool insulation. Now it only takes 5 minutes to heat up 1 degree Celsius on natural gas, which is the least expensive heating source over here.
But:
After using the spa about 4 times, a yellow-greenish "glue/bubblegum" layer appeared on the high, middle and low waterlines (4 people load, 2 people load and empty). So we emptied and cleaned and flushed the system... Takes almost a full day and tons of waters, but okay.
We've been cleaning and filling and cleaning and filling every weekend since.... But once the water level is high enough, and the heat has reached 32C, the bubblegum lines reappear.
All readings from the test strips (came with the spa) are good, over and over again. Our local tab water is the best in the Netherlands, German Hardness less than 3. But we put 2 chlori-thingy tabs on the tray as soon as we see the old ones have dissolved, just to be safe. Our tab water has a light green transparent hue. We use chlori-thingy granulate to shock, but the manual does not recommend that when using the chlori-other-thingy tabs. The packages do not indicate any specifics about concentrations of chlori-thingy, nor is there any mention about the type of chlori-thingy or something else. But up till now we have not seen an indication on the strips that we are doing it wrong. One simple unloaded run and the readings are just fine, within the safe perimeters...
Can someone please explain what this "bubblegum" is and how we can get rid of it? It costs us 2800 liters of fresh water every weekend cleaning the tub!
Thanks so much for "listening".

PS: Vendor/importer has been unresponsive and shown himself to be an absolute ignorant where alternative heating sources is concerned AFTER the sale....
