I'll try and watch the surface next time the cover is off in the daytime, and let you know how the surface flow looks with the VF running at 23 GPM.
Related to the Sunken Treasure, I do find my cover deteriorates. I do use chlorine floaters. My covers (12 mil) currently last about three years before they need replacement, it appears that the water side of the bubbles go first.
While the flow rate is lower, I'm pumping more than double the number of hours right now. So, I'm not sure about the higher chlorine concentration on average over the whole day. The chlorine concentration would certainly be the highest when the pump was off, and there was no flow.
There is another short thread about the Sunken Treasure here:

There were concerns about plaster mentioned.
I wrote an email to the safensavepoolchemist website, and received an immediate response from Kim, the inventor. It still sounds pretty interesting, and she has a US patent on it. Wrote back asking about plaster damage, from tabs directly on plaster, or just off the bottom in Sunken Treasure, here is what Kim replied:

Hi Jeff,
Yes, if you put the 3-inch tab(s) directly on the plaster, chlorine will burn (so-called chlorine burn) the plaster which cannot be removed (like when wood is burned, you won't be able to reverse it back to wood). On the other hand, the Sunken Treasure is well-designed - it rarely stands still in one position and the plaster is protected by Sunken Treasure wall materials. The chlorine tab never comes in contact with the plaster, nor is it possible for the tab to get close enough to the plaster to cause damage. With over 15 years of the Sunken Treasure on the market, no one has ever complained about stains on the plaster due to the Sunken Treasure itself.
