    First opening

    Hello all. This is my first spring opening. I just tested my water and p,urged the numbers into the calculator. I am confused. First let me say that the pool is at 66degrees and is clear. Hooray! It is still covered but circulating. We are constructing a deck and I don't want to uncover until it is built. Numbers are FC .5. CC .5 TC 1 TA 50 CH. 100. CYA 20+ ( real confusion here) and PH 7.5. Do I really want to use bleach instead of trichlor to raise chlorine? With cya so low and ph at target, I am not sure what would be the best route here. I know that the few weeks we were running last year, I struggled with low chlorine and CYA levels, but got by ok I guess. Our pool was installed in August and this site was so helpful. Anyone have some guidance for me? Thanks- Melinda

    Your TA is too low for using tablets - the ph and TA will drop like rocks if you use tablets now. Do you already have the tablets? Using bleach and bumping your CYA level manually with an addition of stabilizer is cheaper in the long run. I would only use tablets if you have them already on hand, just get your TA up to 120 before you start.

    You probably struggled maintaining chlorine because your CYA was too low last year.

    Re: First opening

    No tablets. Start with the huge quantity of chlorine as per the calculator? Baking soda also huge amount, calcium chloride and liquid stabilizer? I am going to add the recommended amounts and test again? I keep telling myself that I can get this. If I could maintain a 100 gallon marine tank full of living things I should be able to do the same with a pool that will be safe to swim in , am I moving in the right direction? Thank you so much for the quick reply.

    Re: First opening

    Unless you have a brand new heater with a warranty to maintain you can skip the calcium chloride because it's irrelevant in vinyl pools. Skip the liquid stabilizer it's too expensive. Get Walmart's stabilizer/conditioner for $16 for 4 lbs. Let it dissolve in an old sock or nylon knee high in front of the return. Don't test for it for 5-7 days but 'ASSUME' its in there and maintain the FC according to the CYA chlorine chart. Use the pool calc to determine how much to add to get you to 50 ppm. How much baking soda are you calculating and what are you targeting? 60-80 if you are going to use bleach is fine.

    If I can survive my induction into pool ownership, (see screenname) become a Moderator on TFP and then start my own pool service, you can absolutely do this.

    Re: First opening

    Thanks, frustratedpoolmom. I am using TFP target numbers. For TA you are recommending 70? According to calculator I need 6 12lb bags of baking soda. I am not sure what you are referring to in your recommendation of 50 in your post. Will you clarify for me. Thanks for your help and motivation.

    What does your water look like? What is your current FC reading this morning?

    Re: First opening

    I'm recommending if your TA is 50 your target should be 80 if you are going to use bleach. I calculate your pool is about 20,000 gallons? That's about 8-9 lbs of baking soda - you sure you are calculating correctly?

    I calculated 25000 based on the length and width and depth of the pool as per TFP.

    Well, that's a nice closing job.

    If it were my pool, I would put a small jug of clorox in (stir it around a bit with a board or boat paddle) and then adress TA when I took the cover off and got the more important parameters adjusted
