algae

Hello everyone, I’ve got a crystal clear pool that always has dead algae at the bottom whenever shock is added. I have to add shock even though I have a SWG because, I assume, the algae keeps eating all of it. I am in the process of SLAMing. I have scrubbed every inch of the pool except behind...

I have the dust at the bottom of pool. If I vacuum it returns. It is super fine and puffs up in clouds when approached by broom or vacuum.I have this problem every single year at this time. I can't believe it would be algae? My water is balanced and my FC has never dropped below 4. My oclt is...

I am a new pool owner (or renter to be specific), I went on vacation for a week and came back to a very green pool. I watched a video online that said to "triple shock" your pool if it is a dark green; I did so and it improved but it was still green, so I triple shocked again and now the pool...

Hi All, I've been trying to resolve an issue with green algae in my pool. For the past couple of weeks I've been following the SLAM guidelines documented here to the best that my schedule allows and don't seem to be making any progress. The pool isn't getting worse but it's not getting better...

My chemistry reading are. Ph 7.2 Free chlorine 5 Residual 3.0 All 80 ppm First time pool owner, 20 foot round, 48 in pool. Heads up our phosphates were 2400+, and I used phosphate remover, twice. The whole 32 oz bottle over 2 days. We have added stabilizer, and finally have this much chlorine...

Hi there. My water levels are balanced yet I have random spots of algae that appear in my corners and on my ladder, along with other various areas (inside skimmer box). I walk around and brush it away, vacuum, add chlorine if needed. The water is crystal clear otherwise. Is there something...

First, thank you so much in advance to anyone who is able to offer advice. We became new pool owners last summer, and an algae issue completely got away from us. We followed advice from the pool store and spent 6 weeks trying to fix it before closing it for the winter and never really enjoying...

Hey, folks. Hope everyone is well. Pool is doing awesome here in central Illinois. Can’t thank you enough for liberating me from the tyranny of the pool-industrial complex. Question: The little glass window on the pool filter is filled with green stuff… algae, I imagine. I don’t...

So at about my breaking point with this pool so I decided to post for some help from the experts. Pool was closed by local pool store and for the first time - when I opened this year it was the greenest I've ever seen. (1st photo) I'm wondering what caused this in the first place as I had...

Can anyone help me identify what type of algea this is? We just opened the salt water pool and this algea is everywhere. The water is clear by now but these stains will not scrub off the walls. The pool is older and has a slightly rough Gunite finish. We have balance and shocked and added algea...

Stay true to the Slam Process, it works. One thing I will say though, make sure your equipment is working effectively. For the last 2 seasons I had my pool chemistry on point but the pool didn’t look like I wanted it too. I finally cut the piping this year to open up the sand filter and there...

Hi there, A pool company just opened up my pool. FC: 1.5 CC: 0.5 PH: Unable to determine (more info below) TA: 50 CH: 200 (using 25mL sample) --- 250 (using 10mL sample) CYA: 0 (I think; more on this below as well) Chlorine I'm sure the pool company added chlorine because the water is a...

Hello i recently opened my pool and had a bunch of junk in it from winter and waterr was really cloudy . Within a few days i had the water sparkling and everything was looking good. That until i noticed that some junk that looks like brownish dirt kept accuumulating on parts of the pool floor...

Hello! I am finally hopping on TFP because of all the issues that began last year and continued into this season. Sorry for the extremely long post. Here is the problem that I CANNOT seem to fix no matter what I do. Last year mid summer, the pool got a little hazy and had a green tint. I...

Hi Everyone - I have some questions about pool opening and pool covers. I have an old loop-loc cover that probably is in need of replacement. Each spring, I spend about a week sanitizing the water in my 43k gallon pool. When I remove the cover, the water is black – it’s disgusting. It entails a...

Hi! We just did the "paper towel in the skimmer basket" trick and within a half hour, it was brown! We fought with a green pool all last summer (first season with any problems of our 5 years with this pool!) and the pool store said it was algae so we shocked and shocked and shocked and finally...

Hi everyone and thanks in advance for any help… so I am a new fiberglass pool (21k gal) owner and although I’ve had the pool for a little under a year, construction is lingering on it on and now we’re getting ready to complete everything. We’re just north of Atlanta so you know what the weather...

Hi, I have this exact problem that is described below in an old/inactive thread in this forum. I have spent thousand of dollars on chemicals of all kinds and vacuums ( thrown out my back). It is not just in the shade and always comes back in the same places. I cannot vacuum (tried manual vac...

Hi everyone, I have multiple green algae spots around the pool walls that I can’t seem to get rid off, I put some muratic acid in yesterday and then shocked the pool 4hrs later… Some has gone but these remaining spots won’t budge! Any help appreciated! Thanks Steve

I posted another thread a week or so back stating that I was going to SLAM pool due to algae (See thread here). After much discussion and an OCLT which produced a result of 0.5ppm it was decided a SLAM might not be needed. On to this week... I see what I think is algae appearing, yesterday...

Hi All, I'm preparing to do my first SLAM starting Thursday night. I'm keeping my water balanced as best as I can until then. I'm waiting until then so I can give it the attention that is needed. Also, it is supposed to rain today and tomorrow, so I'm hoping that will drop my CYA to an...

Hi there! Been reading all of the forums and went through "pool school" twice, but I'm at a little bit of a loss on what to do. ~15,000 Gal. Saltwater Pool Measurements: FW:1.2 Total Chlorine: .22 pH: 7.8 TA: 96 CH: 167 CYA: 5 Phosphates: 495 Salt: 1263 Water Temp: 62F Any thoughts on what...

Hi all , I’ve had a 14” above ground bestway pool for just under a year - and I left it to stew over winter (here in cyprus we have a 3 month winter and then it’s back to warmer temperatures) due to the pool cover being shocking and keep blowing off. When I started cleaning it was a green algae...

Is it true that the use of a chlorine salt generator eliminates the appearance of algae in the pool (I read it here: Why is My Pool Green? | Discount Salt Pool Blog Or is it just a marketing ploy?

Hi guys I have noticed slight algae growth in my pool and cloudy water. Can you help me out a little. I bought a test kit from clear choice labs ... Australia here are my results. Only 2nd time using test kit so highlight issues you may have with results please. Cya. 45 FC. 6 Cc. 1.5 Ph. 7.8...

Hi everyone! I am pretty new here so learning lots. My pool has been difficult this year. I’m either battling a leaky liner, cloudiness or algae. I’ve been in a SLAM for well over a week. The green is gone but like every other time, it stays cloudy. I’d like to close it up but they say must be...

Over last winter my salt water pool was apparently infiltrated with frogs. I removed over 20 by hand so I can’t imagine the amount of tadpoles spawned in there. Unfortunately this resulted in not being able to use the pool all season because we could never get it clear from what appears to be...

When I opened my pool at the beginning of the season, I had an algae problem which might have been mustard algae? I wasn't sure and just treated it that way with directions from this site. The water cleared up and the pool has been running clear all summer (Thanks TFP!). Now that I'm getting...

First year pool owner. I’ve been following the pool stores directions on how to care for my pool. The pool store is also the same company that put the pool in for full disclosure. My pool is now completely green. They keep selling me I’ll decide to pour into it and telling me to turn my...

So, back in July I went through a algae problem which I was able to successfully overcome through SLAM. However, since then, I feel like it comes back so easily even though I have been making sure to keep the chlorine over the recommended levels for my CYA and I feel like I am constantly running...
