algae

So I'm treating a neglected pool... my neglected pool... alkalinity is ... 0 PH is about 6.5 hardness is 33 free chlorine at 0.4 total chlorine at about 3.5 CYA at 76 (although before finding this website i added more chlorine stabilizer, so its safe to say its a bit higher now maybe 80+) I...

We are new pool owners of a 6,000 gallon above ground pool and we have been plagued by algae problems since the beginning. We have already drained the pool twice because it seems to be the only way to rid ourselves of the algae. We are running the sand filter (1,500 gallon/hr) Sand Filter Pump)...

First time pool owner. I forgot to add chlorine to pool going away for a long weekend, and came back to a green pool. That Tuesday I followed the advice on the taylor kit booklet table in the back and added 4 gallons of chlorine to add 30 ppm. Killed the algae overnight since the pool was blue...

Hi! During a multi-day rainstorm, I couldn't keep the chlorine within range. So, we ended up with outflow hoses that are now yellow-green on the inside. My consistent, non-stormy pool maintenance keeps my combined clorine tests at 0.0-0.2, my free chlorine within range for my CYA, and slamming...

Hiya - I'm new here. I have read many posts and responses about algae. I'm not seeing anything that is what I experienced, so I thank you in advance for your patience and help with another algae question. First - yes, I know I need a test kit, and I do not have one yet. So... while I wait...

Long time pool owner trying to fight an algae problem

I’ve been living at the pool store daily, followed their advice and while a couple of things have helped a little, my pool is still green. We have an 18x48 above ground with sand filter (we switched pump to the one it came with yesterday). My first test results (last Thursday) I was told to add...

I’ve been fighting back on algea growth the past few weeks. I’ve finally got it mostly clear, but I just got my TF-100 kit and am seeing numbers that aren’t great. Here’s what I have: TA: 240 Ph: 7.8 CYA: 30 FC: 4.5 CC: 0 (didn’t switch color) I think I need to lower the TA first. I have 128...

My dad's house has fallen into decrepitude the last several years since he's had more and more trouble moving around. The backyard especially has grown into an awful state. The old in-ground pool in particular is one of the large hurdles I'm trying to leap. It's a concrete pool that is 4ft deep...

Hi Guys! I'm new here :) We are in the very LONG process of building our inground pool so we bought a 16x48 vinyl intex pool for the summer. We put it up at the end of May and things have been great until last week. I will be honest, I have never owned any type of pool before so yes, I am a...

Hello! We recently remodeled our pool and added two Hayward Colorlogic Bubblers to our sunshelf. I noticed some water inside the housing shortly after we filled up the pool but didn't think anything of it. The water inside the housing does not have any easy way to circulate, which has resulted...

Hello pool experts. For the last week or so our pool has been a cloudy, possibly from some hard rains we have had recently. I added some Clorox Clarifier/Flocculant yesterday (https://tinyurl.com/jx5dd9bz) and today things seemed to clear up pretty good as everything was now sitting on the pool...

Does anyone have one or both setup on their pools? I am looking for the ionizer to help prevent algae by raising copper levels (clear blue ionizer) then a UV lamp to also help treat the water as it passes through the system. I'm hoping this helps my sanitizer work more efficiently and can be...

Hello again, This last weekend I changed the sand in my filter, retightened all the connections, and drained and replaced more than half the water (removing algae and higher copper levels from previous system). I tested the water Saturday afternoon and continued with SLAM. FC 8 CC .5 PH 7.2...

Hello, I opened my pool on Monday and was treated to a green mess. I brought up my CYA to 30 from 0 and maintained a FC level of 12, checking every 3 hours. After about 24 hours, the pool turned blue, but even now, 6 days later, it is still very cloudy. I have a very oversized DE filter for my...

I have a 16’ round above ground pool. Went to drain the pool the other day (after no use for about a year) and it has algae or something stuck to the sides of the liner that doesn’t seem to come off with anything but scrubbing with a magic eraser. (Which would take days to scrub the whole thing)...

hi, just got back from vacation for 3 wks. Gf added chems while I was gone. I now see some stuff sticking to some of the sides and on steps/loveseat. I think its somewhere between faint yellow and faint greenish. I had her putting in MA and liquid chlorine while i was gone. Test numbers this...

Hi guys, I need some serious guidance here.. my pool installer did a terrible job installing our waterline tile on our saltwater fiberglass pool which we installed last fall. What seemed like just a sloppy install is not turning into a algae borne mess... it seems water is now behind lots of...

We are shocking using the slam method for mustard algae and we are not making progress after about 32 hours. Chlorine just dropped in the few hours we were at a baseball game after holding for most the day. I’m even using a bit higher amount of chlorine to try to beat it. Our alkalinity will...

We installed a pool about 1.5 years ago. We have a VS pump with a UV/Ozone system that uses chlorine pucks. The company is maintaining our pool. We have had nothing but trouble. We have severe burning of the eyes, dry skin, green hair after 1 swim, and now algae. They have tried everything it...

Hi Everyone, I opened my pool last week and got almost all of the visible organics out. I’m on Day 3 of the SLAM. My CYA was high 70, so I needed to get FC up to 28 according to the chart. I’m almost there - FC dropped a little bit after the first day, and I added some additional chlorine...

Hi all. I started a SLAM 48+ hours ago because I noticed what I thought was yellow colored algae in various spots around the pool. It doesn't seem to be disappearing and I can't rub it away with my finger with vigorous scrubbing so could these spots be some sort of stain in the plaster? And if...

Can anyone tell me what this is? We have had this problem since last summer. We have shocked, SLAM’d the pool, taken out the steps and bleached them, changed the pump and most recently the sand. After the pump runs several hours it’s back! We run the vacuum with filter (Dolphin E10) every couple...

I’m a first time pool owner and my pool was super dark green after opening. I have an above ground 18’ round 4’ deep and I can’t see more than about a foot down into the water. I have tried manually vacuuming as much as I can from the bottom but it is hard to tell what I’m doing since I can’t...

I live in Southern California. My chem has stayed within normal limits. However, my pool timer clips slid together and my pump didn't run much for a few days and white mold developed on pool surface. I'm wondering what this brown stuff is. Is it dead Algae? I been trying to waste water...

I seem to have what is either Algae or some sort of stain. My free chlorine has been elevated for over a week and have brushed daily and it does not seem to be helping the stain. When I look closer under water, it has a brownish tint to it. Any advice? Picture below, although I know it is hard...

Hi! Brand new member, and new to pool ownership. In fact...the pool isn’t even finished yet. We bought an “as is” property in July that came with a derelict pool, if you want to call it that. Here is what it looked like in July: By September, we finally got the pool repaired, and the liner...

I'll admit i have slacked off on brushing the pool in the last month because it is still record Dang heat, and I have this dermatology thing going on that i can't go in the sun, but i am surprised to see a little algae forming in the crease of the steps and on the love seat. How can i fix it...

I'm new to the forum and to pool maintenance. I have two questions: 1. I've neglected maintaining the pool the last couple of weeks and it's turned green. It's time to close the pool for a long Wisconsin winter. Is there any good reason to clear up the algae problem now or can I just cover it...

I had some algae grow recently. I kicked butt my first summer with this pool, then I wasn’t able to stay on top of it for a bit and some algae began. 😞 So I SLAMmed, and after a week of removing light enclosures, scrubbing everything, removing skimmer flaps, scrubbing stairs, etc. I passed the...
