algae

Hello! Tis the season to start thinking about opening my pool. I live in Illinois and I have a 15 x 40 inground swimming pool with a deep end and mesh cover. I had a very similar pool growing up, and I remember opening it to clear water. (We had a solid cover). Last year when I opened this pool...

Hi everyone! I live in Orlando and just bought my first home, which came with a pool! It was a nasty swampy green before, but I've been doing a crash course this week and the rehab is going well. I have a company coming Friday just for good measure. I am noticing these white spots on the...

Backstory, bought a house in Wisconsin, with an in-ground, 30,000 gallon (large deep end) vinyl (w/ aluminum walls) swimming pool approximately 4 years ago. We had a leak in the 20 year old liner (pool was installed around 1980) that we needed to replace in 2021. Last year everything was...

This is our 2nd summer with our pool & last year we had zero issues! This year we've been gone a lot, the weather has been crazy hot, then super rainy and we have an absolute mess! Our pool currently looks like a yucky green pond & I am ~this~ close to throwing in the towel & crying! I...

I am having extra trouble this year with all sorts of algae due to the Texas heat. Our pool is about 36,000 gallons (we think) and is about 20 feet from our lake. This means we end up with all sorts of critters in our water daily: frogs, snakes, turtles, mice, you name it. We have a tower for...

Hello Friends, I am so happy to have found this forum. Just a couple of months ago my wife and I bought a little soft sided pool for our little girl - a Bestway 12 x 22’ x 48” oval. On the cheap side, I know. Again, I can’t overstate how educational this forum has proved to be. I...

This will be my first year winterizing a pool. I have kept my pool crystal clear all year using liquid chlorine and the occasional muratic acid. My pool also has about 30 ppm of borates in it. My question is when closing for cold Ohio winters should I add anything to keep the algae away or will...

If I have green algae on the floor of my pool, is it better to vacuum the pool before treating it with CYA, shock, and algecide? Or can something like that only be treated with chemicals and I shouldn't bother vacuming until After the algae goes away with chemical treatment? Thanks!

Our new pool has turned green (sadly it was crystal clean when we purchased it a month ago) then went to Hawaii and came back to this. How do I save it before I fork over $800 to pool cleaning. FYI, I know a big rookie trying to understand my pool.

FC: 12 CC: 0 CYA: 45 PH: 7.8 TA: 100 Hardness: 125 Above ground pool, ~6900 gallons 14 inch Intex Sand Filter I used a TF-100 test kit My pool is green and has some sandy-like yellow debris at the bottom (I believe to be mustard algae). I have read the SLAM process and have been maintaining a...

Hello! This is my first post here ever! So.... My out-of-ground 15,000 gallon pool has been greenish and cloudy for two weeks. TWO /HOT/ WEEKS! I used a bunch of pool store :poop: on the pool to no avail. So, I found this place (thankfully). Here's where I am right now: I flocked the pool...

Hello All, New pool owner. Bought a house with a pool almost a year ago in Southern California. I hope that someone can give me more insight on what they think the staining could be in my pool? This isn't something new and has been there since we bought the house. The pool is roughly 26 years...

Hey TFP, Long time reader first time poster here. I'm hoping to try and get some help figuring out what the heck is in my skimmer. I've got Chlorine and PH in a good place and I recently shocked my salt water pool. I've attached a picture of what I'm seeing every morning I get out to check the...

Hi, everyone. I’m dealing with a small outbreak of algae. This is my first experience with it, so I have a couple of questions. We accidentally left the chlorine generator off on our SWG and, with weather too cool to swim, I didn’t pay much attention to the pool. That was a mistake...

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, so I have pictures of what the water looks like along with the readings: FC: 1.5 CC: 0.5 PH: Unable to determine (more info below; see pic of attempted PH measurement) TA: 50 CH: 200 (using 25mL sample) --- 250 (using 10mL sample) CYA: 0 (I...

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...
