Re: Newbie, advice on scrubbing walls while pool is near emp Here are the aerators in action. 1" pvc, not to be used while pool is occupied :wink: [attachment=1:gwesk7l7]aerators(lo_res).jpg[/attachment:gwesk7l7] The downside of a clear pool - the defects are plainly visible. Like rust marks on...

Re: Newbie, advice on scrubbing walls while pool is near emp Now have Hardness Plus and acid/aerators. Does it matter whether I go after CH first then TA? Or the other way around? Simultaneously? Thanks to Rangeball for the aerator design and Bama Rambler for the help. BTW, the pool, even at...

Re: Newbie, advice on scrubbing walls while pool is near emp Rechecked the CH, still came up 140. Saw many examples of aerators on this site - should have looked first before wasting bandwidth asking. Anyway, will build one tomorrow. Then will start the lower pH, aerate process. CYA being added...

Re: Newbie, advice on scrubbing walls while pool is near emp Hmmm, don't have 'eyeballs', just pipe flush with the walls of the pool. Maybe I can rig up a shop vac to blow into the pool. I'll measure CH again, maybe cockpit error. CYA - The Pool Calc indicated a target of 30 - 50 so I'm going...

Re: Newbie, advice on scrubbing walls while pool is near emp So I decided to empty the pool since the remaining water was too dirty after cleaning the sides. Pool now filled. Results: FC = 0 CC = 0 TC = 0 pH = 7.5 T/A = 220 CH = 140 CYA = 0 Temp = 67.3 CSI = 0.02 I'm following the...

Re: Newbie, advice on scrubbing walls while pool is near emp OK, the pool is now filling. This may take a day. Should I add chlorine as it fills to stop any algae growth? Is it worthwhile to test the water during filling? The next several days will be hot - 100+. Cooling comes by Thursday...

Re: Newbie, advice on scrubbing walls while pool is near emp Thanks Bama Rambler. Here are the results with water as is. FC=3 CC=3 TC=6 Ph=7.2 T/A=240 CH=620 CYA=400 (sample was 25% pool water, 75% well water) I won't be doing anything more until the pool is mostly drained and water replaced...

So I joined last week and been reading posts as I have time. My pool used to be green and cloudy. This season, it's been better, only accasionally cloudy, usually after I brush it or it gets heavy use. Some backgound - plaster is rough, not smooth, black algae present and hard to eliminate; pool...

Just discovered this site. Been struggling with the pool for years - mainly because i didn't appreciate the importance of correct chemistry. just ordered TF100 so there may be hope after all. Thanks to the moderators and others that keep this going.
