Is it ok to replace my current sand filter (Hayward 220T) with a Hayward 244T? Will the larger size affect pump performance, etc. See my pool specs below. Thanks

My 23 year old pool is still in great condition. The Hayward sand filter is the original filter and still works well after all these years. Sooner rather than later it will probably need replacement. I have an opportunity to buy a used 2 year old filter - same make and model -for a very good...

I live in Florida where we are experiencing an early winter. My SWG is no longer producing chlorine because the water temp is too cold so I'm adding bleach the old fashion way. I have the SWG turned off but I'm wondering if it is ok to unplug the unit? I don't know if it draws any power while...

This week, I'm going on vacation for 9 days. Right now my pool is perfect, balanced and sparkling. It has been that way all summer (knock on wood)! The pump, filter and SWG are on a timer and come on automatically so the water will be circulating and chlorine will be generated. While away...

The product is a two step process using a liquid and powder. I've searched but unable to find what exactly each product contains. Anyone know?

I have a Hayward Swim Pure Plus T-CELL-9 SWG that is almost a year old. Up until November I was getting a flashing indicator to inspect the cell on a regular basis, approx every 3 months. According to the manual the reminder/flashing indicator will occur after approx 500 hours of operation...

Current reading: FC = 15 PH = 7.5 Alk = 80 Salt = 3300 CYA = 70 My FC level has been high since mid October and after adjusting the SWG output knob down several times, I finally turned the switch off. The switch has been off for a week now and the FC reading hasn't changed. I'm using the...

In the 60-80 CYA range, why are the Minimun and Target FC ranges much lower for SWGs than non-SWG pools? I've only had my SWG 2 weeks, but I'm getting algae at the lower target range. I'm in NE Florida and we've been getting monsoon rains and perhaps that is influencing the water balance.

I have 2 large tubs of granular tri-chlor. Will I harm the SWG if I add the granular CL through the skimmer? Right now I need to raise my CYA and CH and I'd like to use up at least some of the granular tri-chlor that I have left whenever possible. FC = 3 PH = 7.7 CYA = 50 CH = 50

Want to have a screen enclosure built for our pool. Live in Florida and would appreciate any advice on what to look for and ask contractors as they visit and quote?

Added 32oz of granular stabilizer yesterday morning and have had my pump running 'round the clock. After what period of time should I expect an accurate reading?

Installed my SWG yesterday and added the salt. Salt came from Pinch a Penny in 40# bags. This morning the Polaris was cleaning and picked up quite a few hard white particles - looks like coquina. At first I thought they were PVC shavings that came from the pipes that were cut, they weren't...

Purchased a Hayward SWG and prior to installing, the mfg recommends adding metal remover and algaecide to the water. Manual states for all pool sizes: "The pool's chemistry must be balanced BEFORE activating the SwimPure Plus. NOTE: If the pool does not have new water, add 1 quart (1 liter) of...

Added borates about noon today. Just checked my PH and TA. PH went up to 7.9-8.0 from 7.4 and TA went up from 85 to 110. When should I add more acid to bring down those levels?

I finally have my CYA down to 90 from a whopping 160+. Getting ready to make the purchase and would appreciate your recommendations on the size I should get. Right now, it looks like I'll be going with Hayward and getting the SwimPure Plus or Aqua-rite. I believe they are the same systems...

I'm going to have a Hayward SWG installed in the next few weeks and in preparation - read Waterbear's SWG Water Balance guidelines. He recommends: Are those parameters for all SWGs? If so, help me understand why in simple terms. The Hayward manual recommends TA of 80-120 ppm. For a vinyl...

I read the PH/TA articles in pool school and have a process question. When adding acid to lower my alkalinity, can I keep the fountain on during and after this step? Or must I first ensure the PH has lowered, then start aerating? I wasn't sure whether aerating during the entire process would...

I'm in the process of draining some of my pool water to reduce the CYA level. During the process I started using the magic eraser to clean the vinyl above the water line which has turned gray and black. This stuff works like magic without a lot of scrubbing. It is even taking some of the...

I was a long time trichlor user until I found this site. Made the switch to bleach a few months ago. When I used the tabs, maintaining the pool was very easy in that I didn't need to tend to it each day after coming home from work. That has all changed since the switch to bleach. I find it...

I don't have it yet. But I usually have to treat mustard algae a few times in the heat of summer. Now that I'm a BBBer, I want to acquire the knowledge to prevent it - and if I do get it - be prepared to treat with chlorine rather than supplement with yellow treat or something similar. What...

Just started the BBB method a few weeks ago after finding this forum and learning my CYA is high. Below are today's test results and I'm wonderering where I should start? I will be removing water - slowly - probably to just below the skimmer, so I know I will have to do that often. I'm going...
