Calcium build up in my Arctic Spa Hot Tub

I have an Appolo spa by Arctic Spa, each time when I drain and clean the spa, the calcium build up is something aweful. I have a water softner however the water in my area is hard. I was told by Arctic Spa to buy a product called ''aqua finesse''. I am not sure this product will fix my problem.
Can you help me????

The worst calcium build-up I have seen on an Acrylic shell was actually caused by incorrect use of chemicals by the owner. The owner was dosing in very large quantities which was the cause of their issues. Little and often is the best way to go when adding any chemicals to a hot tub.

I don't rate Aqua Finesse at all. I have seen cirulation lines partially blocked due to similar products, I wont recommend it to any of my customers or use it myself.

If you were my customer, I'd be running through your chemical routine and the quantities that you add at any one time. It's possible that you are over-dosing and causing the problem to get worse.

Kind Regards,
Ian Kime.

Our hot tub temp keeps dropping daily into the 90's temp when it is set at 104 degrees. When we turn the high speed blower on, it seems this is the only way we can get the temp back up to the

calcium will stick to heating element 1st and make it less able to heat water , eventually it will consume the entire surface and insulate the water from touching it and warming it and finally overheat it and cause burnout , high calcium (limestone) is usually a condition that occurs when filling via a well or stream , consider getting a load of pre softened water from a municipal water system , there should be a list of haulers in your area that can provide this service

I have brown gunk sticking to the walls appearing to come from the pipes in my Spa

You have one of four possible issues in your hot tub.

  1. Mold
  2. Algae
  3. Hard water
  4. Calcium
The first thing you want to establish is if the problem is organic or non-organic, because the solution to the issue is different for both. If it is organic mold or algae then you need to drain clean and sanitize everything, tub, filter, hot tub cover etc.. and it may take more then one refilling depending on what it is. You could try and take a sample in a clear jar and put bleach in the jar. If the substance in the water disappears you know its organic.

If the issue is water hardness or calcium then you will need the corresponding chemicals to deal with these issue. We have a chemical called spa control that deals with water hardness. You may also want to use a a pre-filter when filling your hot tub to rid yourself of high content minerals in your water.

Maintenance led is lite. I do not have a manual. Every thing refers to the manual for service. What type of service is required to check and clean? If cleaning is required what is needed to clean?

You must clean the electrolytic cell. Remove the cell, cap one end, soak with vinegar for 6 to 12 hrs to remove the calcium build up. Rinse and repeat until cells inside are clean. You can use light water pressure to remove the calcium..If you have not done this before, you may have excessive build up and will need to repeat this step several times.. Do not poke at the cells as you may damage them...A water hose nozzle should blow out the white stuff inside..

Good luck!!

If you do not keep close watch on your water chemistry, depending on your location , you could have a large calcium build-up or salt build up on your electric heating element. Also, these models are meant for spas, and depending on the weather in your location, the heater might have trouble keeping up.

How do you drain the spa?

There is probably a drain valve somewhere near the control panel ... forgetabout it ... too slow.

Best way is to get a small pump and pump it away. Next best is wet dry (shop vac). My favorite is siphon ... dont have to buy anything or drag anything out ... only a hose. By the time my water is out ... I have had time to do the necessary surface cleaning and waxing.

We have a dreammaker spa, how do we drain it? the model is Fantasy

The Fantasy has a drain located in the toekick of the spa. You have to first remove the drain cap, attach a hose if you wish, spin the outer black ring counter clockwise to start the water flow, then pull the outer ring out away from the tub to increase the drain to full flow.
I understand that a screw driver is often needed to pull the outer ring out to achieve full flow. Therefore, I suggest another method. Take a garden hose and place it in front of the jet while the spa jets are on. This will force water flow thru the hose and prime the hose. Once you see water running from the other end of the hose, drop the hose in front of the spa jet into the footwell and as long as the loose end is lower than the end in the footwell, a siphon will drain the spa as fast as the spa drain will. Remember to turn off electric to the spa once you have established a siphon. You may have to bucket the last bit of water in the footwell. Goodluck.

Have a hot spring spa,i notice a layer of oil in

You caused it, MOST likely

Possibly, it came out of your well or out of your city water supply.

Don't be alarmed and don't be mad. I maintain a hot tub in a resort and in the summer we change the water weekly to get rid of this stuff. We have this trouble to a lesser extent in our other bodies of water at the resort.

What can you do? Go to the pool place and get some of the blue stuff. (comes under several names) The blue stuff works best when the chlorine is low. Put one ounce in a bucket of water to mix then put it into the tub - run the blower and the jets for 15 minutes wait 15 minutes and do it again. Let it run on maintenance speed all night. (never add water to chemical ... always add chemical to water)

What is happening is the blue stuff makes the disolved solids in your water (oil, etc) bind together and either float or sink depending on their specific density. This gunk will be mostly removed by the filter. Clean any you find from the tub (ring around the tub)

Treat your tub weekly (not weakly) with the blue stuff. And also, be very particular about your water balance; pH, Total Alkalinity, chlorine. Calcium is unconsequental in your case unless it is extremely high (above 800 ppm) I presume you know you should have about 7.4 pH, 3 - 10 ppm CL, 80-100 TA or 100-120 depending on whether you use liquid or dry CL.

And lastly, Take a good shower before you get into your tub and insist others who use your tub do the same. I presume swim suits might be optional in your spa (they are in my home spa) if not - make sure they are CLEAN CLEAN CLEAN - after a trip through the washer, rinse them again and let them dry.

This is what I call a 75 cent answer for a 50 cent question. I'm sorry if I overwhelmed you. If I missed your question, please re-ask

Above all else, enjoy your spa.

Vibrations and banging when heater is turned on

wow! That heater that you have is meant for a very large swimming pool, quite a bit oversized, i bet i gets the job done quick though. I have seen before that somebody plumbed in a heater backwards, there are elevated arrows on the black manifold of the heater, make sure inlet and outlet are plumbed in correctly. Make sure you get your water tested. Because the water in your hot tub is no circulating as often (I assume) as a pool would be, the stagnate water sits inside the heat exchanger. What can happen, for instance, if you have high calcium, is the certain tubes inside the heat exchanged can get so clogged with calcium and they are completely shut and the banging noise is due to excessive heat build up inside the heat exchanger. This can ruin a heat exchanger very quickly and the heat exchanger is half the cost of the heater if you were to get a new one. You can check and see if tubes in the heat exchanger are clogged by taking the manifold off of the heat exchanger, and shining a flashlight down the different tubes. However you have to disassemble quite a bit to actually be able to do that.
