    Is this 'dirt' algae?

    I'm not sure what happened to my signature. I was posting from my mobile - maybe that's why. It should show now. There is nothing in the pump basket, there was water leaking from the backwash hose; however, I took apart the multi-port top, took off the basket, cleaned the rotating wheel behind...

    Is this 'dirt' algae?

    FC 5 CC 0 PH 7.4 TA 70 CYA 50 Since yesterday my sand filter has been running much louder. When I went to check on the pool and noticed it, I saw that the pressure was in the mid yellow zone. I backwashed but it didn't help. I shut it off for the night but that didn't help. We had a small storm...

    Is this 'dirt' algae?

    I had shut off my SWG for a day because the FC had been consistently at or above 5 for a while. I allowed it to come down to about 3 after getting the pH down to 7.5 and TA to 90 (although it needs to be a bit lower). You're right my CYA was 35 or 40 depending on lighting, so as you said before...

    Is this 'dirt' algae?

    Last night after sunset 11pm FC 2.5 CC 0 This morning before sunrise 5am FC 2 CC 0 PH 7.5 TA 90 FYI I still get that black stuff at the bottom of my pool that looks like dirt, but it always vacuums right up with no trouble. Maybe it's debree from the pine trees overhanging my yard?

    Is this 'dirt' algae?

    Thanks kcindec. I didn't see your reply before I posted for some reason. I suppose you're right, but I did need the new test cylinder and block, I noticed that the new cylinder is MUCH clearer than my old one and my old Taylor block is missing its top and I used to hold my fingers over it to...

    Is this 'dirt' algae?

    The new Taylor kit is in and here is what I've done and what my readings are now. Initial Reading: TC Above 5 (new oto taylor regent) FC Above 5 CC 0 PH 8.2 (acid needed taylor drops said to add 9.8oz of acid) TA 100 (new taylor regent) I did not test CYA because I did not get a new regent...

    Is this 'dirt' algae?

    Right now I am using an HTH TA regent that I've had for 3 years stored in my garage. My CYA is from Taylor - but the small cylinder that has the black dot has some sticky brown residue on one of the sides. The CYA liquid from Taylor is also about 3 years old because we moved to a temporary house...

    Is this 'dirt' algae?

    It is NOT taylor OTO and it being a good idea to get a new Taylor kit is exactly why I ordered the one I did. So I know it's Taylor regents, so I know I have the right regent for the right block, and because that is the only new kit I can afford. BR I got just from the block, it shows BR on...

    Is this 'dirt' algae?

    I do have a FAS/DBP and OTO test, but the kit has a new ph, new TA, new test tube, and comparison test block in it. That way I can be sure that i'm using new regent along with the correct block/tubes, that haven't possibly been contaminated some how - maybe by time, by residue, or whatever.

    Is this 'dirt' algae?

    I just ordered this kit: Taylor Troubleshooter DPD Pool and Spa Water Test Kit - K-1004-6, but I probably won't get it until next week.

    Is this 'dirt' algae?

    Water is crystal clear. SLAM was completed. OCLT passed. Today's Fresh set of Number: FC = 3 (FAS DPD) FC = 6 (OTO liquid) BR = 11 (OTO liquid) CC = did not test - need new regent, but was .5 this morning PH = 7.6 TA = 60 CYA = 30 (probably because I added water the other day)

    Is this 'dirt' algae?

    Great, thanks. Yes, I did pass the OCLT test. Sorry for it being confusing. I will add some stabilizer to bring up the CYA today. I decided to test the pH with the extra refill bottle I had and I got much better results. Maybe the other regent is bad. With this result, I think I'm pretty on...

    Is this 'dirt' algae?

    I know the r-0014 is recommended, I was just out and found the refill kit with a small test kit from AquaChem on sale so decided to get it. I'll order some for the Taylor kit as soon as I can. In the meantime, what do you all suggest I do with the water? Should I keep my FC where it is in the 5...

    Is this 'dirt' algae?

    I double checked my regent and it's actually from AquaChem not HTH and the test comparison block came with the AquaChem kit originally. Here is what I'm seeing now:

    Is this 'dirt' algae?

    My pH regeant is brand new but from an HTH refill pack of ph and oto regeant only. My swg is off when I do the OCLT test. This morning I wasn't able to get out b4 sunlight but it was only about 3 hrs after sunrise. My FC was 5 which is a 1.5 drop in FC. PH this morning was nearly clear so it...

    Is this 'dirt' algae?

    I guess I'm posting too much since I'm not getting any replies, but I'll give this one more try. Tonight I retested and it seems that my TA is declining, but my pH is still very high. FAS-DPD FC = 6.5 FAS-DPD CC = .5 TA = 50 pH = ? Still very light pink and I guess it's too high to get a...

    Is this 'dirt' algae?

    I did add more muriatic acid yesterday but my ph is still light pink. Is there something really weird going on with my pH or am I doing something wrong? The water is clear, but a tad cloudy underwater. When I put in the pH drops, they suspend in the water and doesn't sink or disperse. I have to...

    Is this 'dirt' algae?

    I'm using 10ml. Thanks for pointing out my mistake. I was counting it as .5 before, but some how must've got mixed up with the TA test procedure. So that means my FC last night was 3.5 and this morning it was 3. But my OTO test looks much higher.

    Is this 'dirt' algae?

    Thanks. I know, what I meant is that the water was clear at 6, but it seemed to clear a little bit more with the extra drop. I'm not positive it got more clear, but it seemed to be a bit more clear. This morning FAS DPD FC was 6. This is consistent with all other OCLT tests I've done. pH this...

    Is this 'dirt' algae?

    FAS DPD FC was either 6 or 7 (clearer water on 7) - which is consistent with what it's been. This was taken after dark. I will do another one before sunrise to double check the overnight test.

    Is this 'dirt' algae?

    Okay, I've added water and lowered PH and tested again. Can one of you please look at these two tests and let me know what my PH is. It doesn't match any of the colors on either of the test tubes. Did I lower it too much? CL 6 (I think) PH ? please let me know what you think TA 80 CYA 35 or 40

    Is this 'dirt' algae?

    Last night my OCLT FC was 7, this morning it was 6. CC stayed the same at .5. I did the night test at about 10pm (after dark) and the morning test at about 5am (before sunrise). Water is crystal clear, no more cloudiness, but there is still black stuff in creased areas of the pool daily. I'm...

    Is this 'dirt' algae?

    My overnight FAS DPD test is: FC 6 CC .5 ** Note, my 003 regeant for the CC is yellow so I'm not sure of the accuracy of that reading. It's been consistently .5 every time I've tested with it).

    Is this 'dirt' algae?

    One more thing, my water level is low due to backwashing multiple times from high pressure on my sand filter. Should I wait until the water levels are right before adding water? Final question this thread: I used morton water softenser pellets the last time I added salt because the store was out...
