New Pool SWG & other questions

[maglib]

New 41k+ plaster pool and I have a couple of questions and opinions to ask?

1We got a SWG and so far without shock we can't get it to produce chlorine levels higher than 1. I have a couple of issues, first the pool is over 41k gallons and the SWG is a Nature2 Fusion Soft 1400 which after reading directions has a maximum size of 40k gallons. Is this a material difference that I should require pool company to replace with one that is compatible with my size? Pool company states that as long as we don't have algae it doesn't matter if the chlorine reads 0 but we don't let algae grow and shock it once we see small black spots on the plaster. We did have a extremely high phosphate level and now got that under 100 and still can't get decent chlorine readings.We also note that it keeps going to "no flow" and just pulling the cartridge out gets it back to flow. Our hardness levels were low and there are no noticeable deposits.

The only levels we can't get correct other than chlorine yet are Ph and we've been adding a half gallon of muriatic acid ever week or more.

2.The pool company promised us a DE filter and put in a cartridge filter. We want DE as we had one in the past and had no issues and loved it. We are now told that they can't install the DE one until after we have final inspections as it requires some drain per code. They said we'd have to put this drain in if we wanted to follow code (nice ethics). Per our contract it says DE and it also says the pool had to be done in accordance with code but there is nothing of course in writing about who would be responsible for the DE drain system (the rep who sold us the pool no longer works there and she said it would be done but it's not specifically written) but now we believe they purposfully put the cartridge filter in and keep trying to convince us to keep it. We met another couple who told us they had a contract for DE and the same thing happened to them. As per the contract the filter is an integral part of the pool and for the DE filter to pass local code a drain is required so hence I would believe the pool company should pay. Thoughts?

3 a return has rocks or plaster peices in it about the size of a half pinky (a couple of pieces). The pool company says will dissolve on own and not to worry.

4. concrete was contracted through pool company with 3rd party. Concrete cracked immediately and is discolored and has rolling edges, sloppy repairs, yellow and dark discoloration (45 days later) and is dirty from plasters boots along with just sloppy workmanship. What would you do if you were in my shoes. They already tried to bleach the concrete and the pool company's guy said it was one of the worst jobs he's seen but I'm sure he wouldn't repeat that to his boss. I want the cracked and severely discolored blocks replaced but 1 is near filter basket and another is a corner. Of course they don't want to do anything. I can't believe they just want to fill it and nobody wants to clean it. They are blaming my loamy orange soil. Hello, they knew what soil i had and they also need to deliver me a clean finished product as i didn't buy a broken, cracked pool. Note they've been paid and the only $ I have is still the $250 for finals.

5. How much water can I expect to lose when the temps hit 100 degrees for 3 days? I have full sun. Would 3" be a lot?

Any help and opininions would be extremly nice. Note I did check the company out in advance and amazing still have a number of issues. Thank you in advance.

(Note we've been running the filter almost 24 hours for 3-4 days and 12-15 the other days.)
