I'm new to the spa thing. Exactly 2 months since delivery/fill. I have a Marquis Quest with the SpaFrog bromine and mineral inline cartridges and UV ozone. I've had in ground pools for the last 8 years and the chem balance on those was no problem, but this spa is driving me nuts.
I've tested the water myself and taken samples to a local pool supply place for testing (the dealer I purchased from is in the DFW metroplex, but still 25-30 miles away). Everything tests near "spot on", PH 7.6, TA a little low @ 60, hardness 160, zero metals, not tested for TDS but the guy @ Leslie's said with convincing authority that 2 month old city of Dallas water would be fine on TDS. Other than the SCUM, I have had no other water issues.
Problem is the SCUM that forms at the waterline. It looks like chicken fat. Totally gross. I've tried the enzyme scum eater products. I can't see that they help at all. I only rinse out the bathing suit, so soap is not the problem. I don't normally shower before soaking, but I don't think I should have to under normal conditions. Cannot believe that a little antiperspirant could cause all this.
I use the spa almost daily. Recently just me for 45 minutes in the morning, at least 5-6 days a week.
I get what I consider to be normal foam levels with the air on (small clear bubbles that dissipate quickly and virtually none with the air off) except that I do get larger greasy looking bubbles/crud in eddys, and that is where the scum forms.
I first thought that I was keeping the sanitizer levels too low, and maybe not shocking enough (I use MPS for that). This past week I've upped both. Bromine has been 3-5 PPM and I've shocked it hard 3 times this week. Don't think I'll be able to get back into it for at least a day since bromine is reading over 10 PPM.
I've cleaned and swapped out filters.
I did try a cationic polymer clarifier after I did get soap from friends bathing suits, and am thinking that may be the culprit, but that was over 2 weeks ago and I would think that it would have worn off or whatever by now.
The water is crystal clear except for the SCUM.
Any help will be greatly appreciated. I really don't want to drain and refill yet.
One last thing. A question about bromine levels indicated on test strips after shocking with MPS. After a shock the bromine reads really high. Is this due to the shock reverting combined bromine back to free bromine or something else? Does the MPS cause the test strip to read inaccurately for some time (MPS does not directly increase the bromine level does it?)
Again your advice will be greatly appreciated. I'm probably overly obsessive about this, but if I can't get this under control it is bye-bye spa.
Thanks,

OK Willie, lets not do anything rash. Put the sledge hammer down.
My suggestion is to actually switch the sanitizer you are using. One of the problems that some customers of mine have with bromine is that it is harder to work in maintaining a level. and problem solving.
What if you try switching to di-chlor granular chorine. put 1-1.5 tsp evertime you get out ( or 2-3 x's per week.) and use your MPS as a suplement to that and use it once a week.
This will give you a boost immediately after you get out when you need it most and by the next time you get in there will not be any chlorine odor.
I would think that this would help eliminate the scum.
Or maybe stop eating KFC in the hot tub. ;D

Three steps:
1.power off to spa.
2.drain and scrub out spa.
3.refill and reheat spa.
I have told my customers for two decades now: water change at the end of the first month of ownership. Also: water is the cheapest (and most effective) chem you can add to your spa.

2A: rinse out the spa

Chas:
Scrub it with what? Just water and a brush/rag, or is there a "product"? What about vinegar/water solution?

You don't say if you have a dirty duck (or one of the other ones on the market). If not I would recommend it. I had scum line too, did the drain, clean, etc and added one of these. Not sure if Mr. Duck should get all the credit but he sure is doing his job. :)

I bought scum balls from Doc's site. I had also heard people using tennis balls, so that is what I have now. (Hubby found a bargain.)
They sure have helped. I don't know how they work, but I had some of the problems you described at first.
Good luck!!!
You might consider a partial drain. I know others, (wmmcall, for one), who swear by it.

You mentioned pool experience. Water gets nastier faster at hotter temps. Add in that your ratio of bathers to gallons is a lot higher in a spa, it is more difficult to manage, but we all get there eventuallyI initially had scum problems, then started doing just what saledvl suggested. Now the only scum problem we have is shown below.

Now that's funny--I don't care which team you root for!
Thanks for the laugh, Terminator....... ;D

What the heck is a "dirty duck"? I've had real ducks in the pool before and there is nothing that messes up the water faster than duck poop. Seriously, I guess the duck is like a scum ball? I've had one in there, and yes it attracts the scum, but it does not do enough and the scum still forms at the waterline.
Think I'm gonna drain it today. I'm gonna stick with the bromine for this next fill cycle. Main reason is that with my purchase, I got a year of bromine cartridges for the SpaFrog and since I have it, I'm gonna use it. If this fill goes south, I'll probably switch to di-clor. The bromine cartridges are just so easy. Are the di-clor cartrdges for the SpaFrog? I've not seen any on King Technology.

Scum bugs are a cheap accessory. Every spa should have one. You can use your Frog mineral cartridge with dichlor but you will have to eliminate the inline bromine cartridge or just keep it empty.

this spa is driving me nuts.
A pirate walks into a bar with a steering wheel sticking out of his zipper. The bartender says, "Hey pirate, you have a steering wheel sticking out of your zipper!" The pirate says, "Aye, it's driving me nuts!"
Didn't fix your problem, but I bet you're laughing. ;D

Still sitting here shivering me timbers over that one...

Thanks for the laugh IBinit4fun!
Next question: what's the best way to get that last few inches of water out that wont drain since the rocket scientists over at Marquis could not figure out how to put the drain at the bottom of the spa. I quickly looked at home depot hoping for a sump pump for about $30, but the cheapest one was $70 and I still would have had to rig up discharge piping or a hose connection. Since I was pressed for time, I did not want to build up something right then, but probably will for the next time. I'd bet some of you have come up with some clever ideas. Maybe using a cheap pond pump or something.

Hey Txwillie (neighbor to the south)!
I use a wet/dry vac! Gets the last remnants of water out for me!
-
Hey, Hey Lori! GREAT idea. Simple and I already have one.
And look, I'm not a newbie any more!

Remember that old "Make a scoop by cutting off the bottom of a bleach bottle" trick? They work great for bailing out that last few gallons of water that doesn't make it down the drain. Simple and fast.
I use one to scoop the water from the spa seats to the bottom of the spa.

Shop Vac. Not terribly expensive and you'll find lots of uses for it.
The good thing about the Shop Vac is that you can get all the water out of the jets too. Just put the hose up to the jets (start from the bottom jets, work your way up). You'd be surprised at how much water is in there. I don't know if this is necessary for every drain and fill--but definitely if you are switching chem systems.
-
I used a wet vac on the jets when I switched from Baqua to bromine. It was suprising how much water I removed that way. But on other water changes I never bothered to vacuum.

OK, I'm reading from the last post to the first, the pirate joke got a chuckle but this killed me!

I didn't think anyone got that one!

I got it, and it was very clever.
And the irony that you brought "him" up in a thread with the subject of this one wasn't lost on me either!
