Folks,
I've been doing the TFP method all of 6 weeks so far with great success. But I'm noticing weekly a very slight amount of greenish algae in a few 1' diameter spots and barely visible. You can't see it on a photo at all. When I see it I run my PoolCleaner and it's gone in a few hours. Other than this my pool is perfectly clear. I've kept within range on all the tests (see below) only my CYA has been low. We departed the house for 3 weeks so in preparation I raised the FC to 16.5 ppm with liquid chlorine, pH went up to 8.4 and was adjusted back down to 7.4 in a few hours with a split dose of muratic using the Pool Math tool. I also loaded the chlorinator with 5 trichlor tablets and a lowish setting of 1.5 out of 5 that seems to be sufficient to keep chlorine levels adequate in normal operation. Each time my filter pressure drop increases a little over 1 psi I clean it with a comb-hose cleaner. This is where I can confirm I'm getting green algae. The filter has what I'd call a light coating of this plus a little sand and dirt. It cleans off very easily and the filter lasts about 2 weeks before I see the pressure drop increase slightly. I'm running the pump 10 hrs per day which should be giving about 3-4 turns per day (based on pump curve and discharge pressure).
I live in S Florida and we get a LOT of sun and a lot of rain (short bursts). The solar heater alone gets the pool around 88 each day. So here's my question about algae: Should I slam any time I see any algae? I've got a feeling I may have to be doing it all the time if that's the case as there is a swamp behind my house that continuously "inoculates" the pool with algae via wind. Other than the green algae in the filter it isn't a problem. So I'm not sure if I'm on the verge of a green pool one day or if I'm seeing what I should expect in my situation. I should also mention we have a light load of my wife and I for an hour or so in the evenings and the pool is screen enclosed so we have almost no leaves etc. I'm hoping the consistent 0 CC reading and the two occult tests I've done with 0 readings(not shown below) indicate I'm OK.
I'd appreciate much if you experienced people here could just do a little "hand-holding" for this newbie that lacks confidence even though the pool looks perfect.
Here are my test results and actions:
