does it clear out the dead algae that lies on the floor of pool? the stuff that if you stir it up, it makes the pool cloudy?

I can't answer your question directly. My issue was the cloudy mess that was left over from the dead algea and yes, it did clear the mess up after a couple of days of running the filter. I hope this helps you.

When I had algae on the bottom of pool, I stirred it up by brushing first (which made pool water cloudy and nasty) while pool was running, then I poured the Pool First Aid into the pool. Then let pool ran for more than 10 hours for 3 days before seeing sparkling water in the pool.

Yes...our pool has constant debris from the woods that we live in and this stuff is absolutely great for our pool. Some people may not have as much organic material to deal with and may not have such raving reviews about this product, but our pool seems to like it!! You do have to vaccuum a couple of times a week though until your pool is clear.

Yes it does clean everything off the top of the pool surface. We run it, non-stop, taking it out only when the pool is in use. Well worth the money. We did add one length on hose to it, as we have a very large pool.

No. The vacuum will remove the dirt but will not take care of algae spores or rain related pH balances. You still need to check your Chlorine/Bromine levels and pH. A pool your size should only need little corrections with the appropriate chemicals.

Yes it kills the good bacteria also, but only the bacteria that runs through the machine. You water is cloudy because you have too much bacteria in your aquarium so killing some takes the cloudiness away. Just a note...I got cloudy water because I was feeding too much. Remove 20% of the water weekly and lower your feeding amount and you shouldn't have trouble with cloudy water.

The algae needs to be DEAD to sweep it up with any vacuum. So either shock the pool, or get an algaecide. This vac will sweep the dead stuff up just fine.

I have not had to clean it. While I have not written a review, I believe if your pond already has a full algae bloom, this product will not help. If you are using it as a preventative maintenance, then it should be ok. It did not clog at all while I had it running (one month).

I know from reading that it have copper in it that help..i add it 2 time to my fish tank and its been 2 months now still no algae ..even the filter is clean. i have shrimp and neon and there are doing good.

It works great on algae on a concrete pool, but I haven't had a lot of luck with calcium deposits (or rust for that matter).

Depending on the size of your pool, this product takes forever to clean very little. It picked leaves and larger items up well. Sand and other residue - not so much. It stirred more up than it sucked up. I have a 16' x 4' round above ground pool. --edit - just realized you have a spa. May be ok for that. I just wouldn't expect a lot of bang for your buck.

Yes, I blew it last year not putting chemicals so had quite a clean up with serious stuff. I had a pool cover which kept the leaves out so didn't get one of those floaters to keep the pool in balance. Good luck and enjoy

It does make the water slightly cloudy. At first it appears clear, but after awhile a cloudy substance settles to the bottom and doesn't go away when swirled around.

I have tried to keep it away from direct sunlight and sources of heat, and that has worked for me for a few years. I also try to keep it fairly full or I'll notice condensation on the top of the bottom segment that holds the filtered water (that is visible in the clear container). Hope that's not confusing. I would make sure everything is fully scrubbed before starting a fresh batch - it only takes a little bit of algae to grow into a mess you don't want to deal with. You could use a diluted bleach spray to get rid of it....just make sure to thoroughly wash it off!

We have a vinyl lined pool, and don't get a lot of algae, or perhaps the Zodiac takes care of it. From time to time if I don't run it or keep up with the chlorine I feel the bottom and sides of the pool are a bit slippery, and after a run it seems ok. I'd generally say it works fine on algae.

it clears the water of any cloudiness. it does not turn the water blue. pool water will always reflect the color of your liner.

We filled our 20,000 gallon pool with our well water (which has a ton of iron in it). When it was full the pool was orange. We used chlorine and pool magnet plus and the water was clear in 8 days. The pool magnet helped the iron not stain the liner or stairs. If you just want help with cloudiness, this is not the product for you. I would overcompensate with Clarifier.

No. Algae usually sticks to the pool walls and this doesn't work. You have to use algaecide and treat it well then brush the walls and backwash. As a preventative measure I use a chemical called "Phos free" it neutralizes the phosphates in the water so there is no "food" for the algae. Algae uses phosphates for their intake just like plants. With no phosphates algae cannot survive.

Actually, it reduces algae in the water. The decorations will still collect weird little globs of algae. It more for water clarity than algae remover.
