Rust In The Pool That Looks Like Algaeby Tommy
I think it is algae. It will not rub off. I put in Yellow Out, shock, algaecide 60, 6 gallons of bleach and nothing seems to work. Also cleaned the filter. Now I am lost all of this was over 2 week period. Thank you for any info. Thanks for the question Tommy First, I'd like to have your complete chemicals readings: Chlorine CYA (cyanuric acid/stabilizer) pH Alkalinity Calcium Hardness Metals (iron/copper, if applicable) What's the size of your pool? It makes troubleshooting much easier and the process of clearing up your pool will go much faster. You can get your chemical readings at your local pool store. And get a good pool test kit. A Taylor FAS-DPD K-2006 is one of the best. Pool Water Testing Water Testing Kit Without these numbers I'm just guessing at what the problem is. You probably know that bleach is watered down chlorine, about 1/2 the strength. Are you sure you put in enough bleach to reach 12ppm? Do you have an inground or above ground pool? Does it have steel walls? It could be rust from the steel, or the early stages of an algae bloom. First, you need to determine if the spots are organic or mineral. So here's what you can do. Get some ascorbic acid, which is nothing more than Vitamin C. Check your local pool store for this. Put the acid in a sock and place it on the spot for about 1/2 hour. If the stain lifts or fades, it's mineral, or high iron and/or copper. If not, get a sock, put a chlorine tab in it, and put that on the spot. If it fades, it's organic (algae), and then you'll need to shock. For an ascorbic acid treatment, you can go to this page that outlines everything you need to do: Brown Algae Won't Come Off Of A Vinyl Liner For a pool shock, you can go here: Swimming Pool Chlorine Pool Shock Pool Chlorine If you can get back to me with a little more detail and answers to the questions above, I'm sure I can help. Hope to hear from you soon. Robert Comment: Cloudy Water After Ascorbic Acid Treatment By: Tommy Date: July 15, 2011 Thank you for your help the ascorbic acid worked great I could not beleve how fast it worked then about 3 days later it got very cloudy can't see the bottom. Pool is 16 X 32 inground, no heater, pH-7.2, total chlorine-0, free clorine-0, total hardness 100, total alkalinaty-180, cya-30-50. This pool is pain in the butt this year. Thanks again Answer By: Robert Date: July 15, 2011 That's great the ascorbic acid worked. Testing the problem is the first step. The acid treatment wouldn't cause your pool to become cloudy. Be sure you're still filtering 24/7. By the looks of the chemical readings, there are some things that can be fixed. First is the alkalinity. The proper range is 80 - 100ppm, 120ppm being to top end. Pool Alkalinity Total Alkalinity You'll want to add the acid in the evening with the pump off. Very gently sweep the bottom to break up any acid spots (acid is heavier than water and will sink to the bottom). Let it sit for 3 - 4 hours, turn the pump back on, allow for one turnover of the water, 8 - 10hours, then retest and make another adjustment if needed. You can get a 5 gallon bucket with pool water and then add the acid. Remember the gloves, goggles, and long sleeves. Do this in a series of steps. Don't add all of the acid at once because if you overshoot the mark, you'll need to increase the alkalinity costing more time and money. You're not far off at 180ppm, maybe 2 applications should do it. The FC is low, obviously, but the CYA is right in there, between 30 - 50ppm. This is good. Slowly bring up your chlorine level. Use maybe 1/2 a gallon at a time. You'll have a higher than normal chlorine demand. This is normal after an ascorbic acid treatment. Swimming Pool Chlorine Pool Shock Pool Chlorine Do this in the evening as well. Put the acid in and wait the 3 - 4 hours, then turn the pump back on and add the chlorine. Remember to sweep the bottom and sides to break up any hot spots of chlorine. You'll see how the chlorine holds through the night when you retest in the morning. Take both (TA & FC) readings in the morning. You can use the 5 gallon bucket technique with the chlorine as well. Use a PVC pipe or stick to stir it up. Be sure you rinse the bucket out before each use. Get the chlorine in there quickly because if you don't you might on the verge of an algae bloom and that'll be alot of time, money, and chlorine. Hope this helps and let me know how it turns out for you. Robert
