New SWG Pentair IChlor-30 in my 20,000 gal. pool. Everything has been fine up until now, but unit suddenly shut down due to low salt (flashing red light indicates <2000 ppm salt level). Did a complete analysis two days ago and everything seemed fine: pH 7.5 FC 6.5...

Greetings, all. It's been some time since I have posted on any forum, mostly because my pool has been "trouble-free" thanks to this website. I am now dealing with the hot tub at my vacation home in PA, where I am isolated due to the virus. My usual service guys are prevented from working due...

I have been using BBB for several years and have been entirely satisfied with the results. I generally follow the simplified FC/CYA chart and do an OTO test and chlorine addition each evening to adjust to the recommended target or slightly above. Depending on sun and bather load, I stay above...

BBB working great so far after Spring Baquacil conversion but I am a little concerned about getting accurate CYA readings. The test is so critical to proper treatment yet it is so subjective. Today I did my normal Saturday am readings and got an initial result of between 50-60. Last week I...

Everything seems to be going well in my first BBB summer, but just wanted to get a little fine tuning advice (or at least explore differing opinions, as I know that after a while pool control becomes quite a personal process). Saturday am numbers are: FC 4.5 CC 0 TC 4.5 pH 7.6 TA 100 CH 70 CYA...

Recent convert to BBB and looking good so far. Reading as follows: FC 3 CC 0 CYA 30 CH 80 TA 80 pH 7.5 I check pH and FC in the evening, add bleach as required. I shut the filter down before I go to bed and turn it back on in the am. Saturday morning complete chemistry with the TF100...

I know aeration can reduce TA at low pH (7 - 7.2). I reduced mine from 100-90 ppm merely by directing the flow outlets upward. Pool now in balance: FC = 4 CC = 0 pH = 7.4 CYA = 20 TA = 90 CH = 125 (at last check) I like the effect of directing the jets upward. It keeps the surface moving...

New to BBB after Baquacil conversion. I understand that proper balance and maintaining the right FC will generally prevent algae. However, stuff happens, right? I have read about borates and also poly-quat 60 as acceptable algaestats (note: I believe only chlorine to be an effective...

After suffering with Baq for the last few years I am ready to switch. I started last season by withholding the Baquacil and leaving the pool open longer than usual to aid decomposition. I used sodium monopersulfate regularly during that time. I did not want to chlorinate as I have a DE filter...

OK....so I toughed it out this Summer with Baq and developed my back muscles brushing nearly everyday to fight off the algae. Tried all the new hyped additives (CDX, etc.) and am convinced that conversion is the only way to go. Pretty sure I know how from all the great posts, but I want to...

Reading all the conversion posts. Have used Baq knock-off for many years (6 or 8, I can't remember). Convenient because I travel a lot and it needs less attention than chlorine. Last couple of years I have battled algae continuously. Water is clear; growth is on walls and bottom. Getting...
