I have finished my transition from a 14K abv to the new ~32K igv. Last year I used lc (had too many higher priority items to replumb for the swcg.) Typical usage was 1gal per day. Cya then was 30, kept the water at a FC of 4-5 perfectly. This year I installed my RJ30+ (1.5# per day.) Knowing that it was undersized by TFP standards I opted to install a Speck VS pump to run 24/7 @ 200 watts (I may drop that as I fine tune the system) rather than replace the cell. Why throw a perfectly good cell away..... My expectations were that 75% run time might be sufficient to maintain 5% with Cya of 70. When my FC reached 15 I started backing off the run cycle. I'm now down to 40% run cycle and the FC has slowly dropped to 10. The shape of the pool makes it hard to estimate - 19X39 with an 8 ft deep end, sloped sides. Either the RJ 30+ is overproducing or the pool is a bit smaller than the volume I'm using. The previous owner said it was 35K per the pb. I didn't argue but knew better. Is my math off that far or am I just having good fortune from an exuberant swcg?
