    Problem with algae growing behind pool lights

    I have an issue where green algae grows behind my pool lights. I have no issues with algae anywhere else, the pool is crystal clear and well balanced. I pull the lights out and clean them but a month or so later you can start to see it again. The algae mainly forms on the pool wall where there...

    Is my SWG cell worn out?

    Thanks, I will try this. Must it be liquid or is granular ok too (Calcium Hypochlorite with no added CYA)?

    Is my SWG cell worn out?

    Ok here are some results. Chlorine went up yesterday, pool cover was off all day. went from 4 at 8am to 5 at 6pm on a cloudy day, then down to 4 at 6.25am this morning, so a loss 0f 1 overnight. I want to repeat the OCLT as I tested not long after the SWCG turned off so would like to test again...

    Is my SWG cell worn out?

    Thanks for the ideas, I will begin with an OCLT and will come back with this. To answer your questions: * Yes it is a G25, CRAD_oz what formula do you use to calculate 3.3ppm/hr? * 7 down to 4 over 3 days with the output at 95% approx (1 day the cover was on all day), I don't turn it to 100%...

    Is my SWG cell worn out?

    The FC level in our pool is dropping, I have the SWG turned up to almost 100% but it cannot keep enough FC in the pool. Over the last 4 days it has gone from 7 down to 4 The pump and SWG are running 10 hours each day The pool is being used almost every day There is adequate salt in the pool...

    How often do you brush your pool?

    I have a concrete tiled pool and brush it once a week, I don't have a robot but in the future I would like one to lower the amount of manual cleaning needed. I listen to a weekly podcast that runs for around 18 minutes. I haven't been able to get my pool brushed and manually vacuumed before the...

    pH is not increasing

    I must get around to testing my fill water. Thanks for the reply

    pH is not increasing

    Yes just the grout in between the tiles. Certainly not complaining, just trying to learn and understand as everywhere you read talks about pH constantly increasing and I am not experiencing that.

    pH is not increasing

    The pool plaster is certainly not new, the pool is 25 years old The test kit is also quite new bought in June, however I also have an old 4in1 test kit that I inherited with the pool, I sometimes use this for the pH test only as I find it easier to read the pH test with this kit and I like to...

    pH is not increasing

    From everything I have read and been told the pH in SWG pools always increases and you use acid to lower it to keep it in the range. The pH in my pool has not notably increased in over 2 months. It sits happily at 7.6 and barely increases. Every time I test it it reads 7.6. It *may* have been...

    Is this algae?

    Thanks, I will try this and see how it goes

    Is this algae?

    I think I have fixed my issue so my PM logs should now be viewable. I am hoping someone knowledgeable can confirm that this is just staining, the fact that it only appears on the bottom of the pool not the sides, plus the fact it is only in the grout and not on the tile itself and a passed...

    Is this algae?

    ok worked it out, but I worked out my account is not linked to this one, anyway my test results are above. Hoping for another opinion on the above, I am hoping that because it is not on the sides as well that it is just staining from the leaves

    Is this algae?

    ok does anyone know how to make my PM logs visible? FC 5.5 CC 0.0 (0.5 yesterday) pH 7.6 TA 60 CH 400 CYA 60 SALT 3600 I only have a manual vacuum, no suction cleaner or robot, so its just brushing and a manual vacuum once a week, twice a week if its windy and I get more debris.

    Is this algae?

    Settling in to around 10 months of pool ownership and I like to think I have the basics worked out now and generally maintenance is going well. I have started to get what looks like algae growing in the tile grout. The brownish/black spots you can see in the grout. Though this is only growing...

    Will low CYA cause green algae?

    Other thoughts that come to mind are, I tend to test in the morning so with a low CYA perhaps the FC is used up significantly during the day and replenished by morning so I never see the drop. Also I recently had what may be considered a FC sucking event (see my other thread) I cleaned out the...

    Main drain and where does this skimmer pipe go?

    Hi Jim, only benefit I thought was I have read that some main drains also act as a return and help keep the floor of the pool cleaner and to improve water circulation. Other than that I just wanted to confirm how I thought it was plumbed simply to understand how it works better. Cheers

    Will low CYA cause green algae?

    Thanks for everyone's answers. I test FC, CC, PH every week and TA and CH every other week, just didn't test CYA untiI the pool would be used again. I don't believe the FC dropped below 6-7 at any point but what I do think is that with a CYA of only 40 with a SWG that 6-7 FC was not enough to...

    Will low CYA cause green algae?

    Using the TFP FC/CYA chart my chlorine is too low for CYA of 40 with a SWG. I am wondering if this was the cause.

    Will low CYA cause green algae?

    Pool water has been warming up with solar heating and currently around 22-24c, 72f The SWG was running as normal over winter, pool wasn't closed. FC levels were 6-7 over winter consistently.

    Will low CYA cause green algae?

    I have a small green algae outbreak so am performing a SLAM currently but would like to learn why it happened. I haven't tested CYA in 3 months over winter (Australia) and it last tested at 70 but when tested today it is now 40. All other results were good FC 8.5 CC 0.5 (first time it has been...

    Main drain and where does this skimmer pipe go?

    Here is a photo of under the skimmer basket, just the one return to the pump, and a pic of the equipment pad. There is only one return to the pump so I don't believe the capped off pipe leads to the pad I believe now that the blanked off pipe in the skimmer DOES lead to the main drain which is...
