THroughout the season I have used the TF100 FAS-DPD test quite a bit. There is a black film that has formed on the vial and I was able to get most of it off with just water and wiping it down good. It still looks stained. I have the same black residue over the spoon for powder. Can I use MA...

Went to buy some MA today and they were out at the hardware. Right next to it was Sulfuric Acid for about 20% more in cost and 1/4 the size. I was unable to find the concentration on the bottle. Is it safe to use Sulfuric Acid to lower PH in a pool? Anyone have an idea how much one quart...

I have been working on lowering my TA from 140 to 80 and am confused where I am at. I realize I still need to work it down some more. This is with the TFTestkit. On the 8th drop after a good swirl it is still a solid green. On the 9th drop the solution turns this COLOR and on the tenth it...

I have had a very difficult time clearing my pool all the way back to last Fall. IT started out as a bad Algae bloom which I cleared before winter. When spring came I fought for numerous weeks and even posted on this forum about having a difficult time clearing the haze in my pool. After...

I am looking to buy a cartridge filter system for my pool. I have an opportunity to get a used industrial grade unit that meets my GPM and is over my cartridge area needs pretty cheap. My question is if anyone has any experience with either the technical specs of the micron level in the...

This is my first season doing BBB and I am going through waaay more clorox than I thought. I am averaging at least 2-3 points of FC a day trying to hold a 5FC based off my CYA level (30 with a 3-5FC range). I realize the CYA/FC numbers are based off experience, theory, and probably the worst...

I may change out my current filter system and found some commercial Filter housings that will accept both cartridge filters and bag filters. The bag filters are very inexpensive and come in all kinds of Micron levels. They have models that meet my GPM needs, I started looking further and...

I have heard various opinions on FC usage per day. I realize temperature, bather load, where you are trying to hold your FC at, etc all plays a role. I have created a survey for us to get a poll for normal conditions in the way you operate your pool what is the typical daily FC usage (round to...

Perhaps this is somewhere in a chart at TFP... I had typically tried to keep my FC towards the high end of the FC levels on the CYA/FC chart in Pool School. I noticed the pool calculator it goes a little higher for a CYA of 50 (4-6 vs 4-8). I started to think, I know anywhere above 4FC as far...

I was having a discussion the other day with a chemical engineer that is responsible for water treatement for a manufacturing plant. We were talking pools and I was sharing some of the techniques on this forum about the lower alkalinity by the add acid/aerate and the borax/add MA thing to...

A history of events... Last year: Last fall I had algae pretty bad and fought it off and on for 3 weeks before getting the FC to hold. Right when I got it Algae free (FC holding overnight and less than 0.5fc) my neighbors tree kept dumping leaves in the pool. I ran the pool for over two weeks...

I am in the process of the lower PH/Aerate technique to lower my TA. I was using the pool calculator and was trying to go from 7.5oz to 7.1oz and it shows I need 41oz of 31.45% MA. I went to the bottom to see how much this 41oz would impact the TA using the effects of adding chemicals and it...

I have been contemplating of adding Borates to my pool with all the positive feedback about easier on the eyes, better feeling on the skin, less chance of algae, etc. But I have also noticed numerous claims of the same benefits with those that have their salt levels up for a SWG. I do not...

I am going to buy my first pool cleaner and have had trouble finding the answer to my questions in the forums. I want to buy a pressure side model but am trying to figure out a few things. I do not have a booster pump, thus am looking at the few models that will operate with my setups 13psi...

Was trying to setup a simple poll so users could select their state and what month they open their pool. I seen it was limited to 10 entries so I would have to do it by region but I could not find a way to have it do two comlums (location and month). Is there a way this could be done by admins...

I tested my water a few days ago to facilitate the buying of chemicals for my spring balancing. I was wondering if there is a specific order and wait periods in-between for balancing, especially for a spring start-up? I had the following results: TC 0 PH 7.2 TA 80 CH 200 CYA 35 Temp 50 -...

My son has a birthday the end of April and I will really be pushing things having the water ready that early in the season for us. The outside temps may be decent (late 70's) but I will have to fire up the gas heater because the ground and my pool water will be in the 50's. I dont want to...

I understand the core concept that the various methods for sanitation creates FC in the pool and that creates a disinfecting mix that dissolves the algae. I have two questions about this process: 1. Going back to laws of "you can't create or destroy matter"....If the FC created has transformed...

I have a concrete/vinyl pool and the pool has a four foot perimeter around it that is all concrete. It is very dull and old looking. I just want to finish the pool area, not the pool itself. Exploring options and have some questions: 1. Painting - If I paint it what is the expectation...

I know this is way off topic but was wondering if any members had any good websites/resources/info you could refer me to for setting up the server side for thin clients and XP. More specifically I have a pretty good XP Pro SP3 computer and have a few monitors/keyboards/mice from older computers...

Was thinking it would be nice going into the forums to find which ones are the most popular (views). Is there a way to or add a way to sort within each forums by ( Topics Author Replies Views Last post ). I think there is a way to do it within the search area but it would be nice to...

Kids and I wanted to "experiment" with our new TF100 kit and I did not want to go through a lot of reagents. I observed at a quick glimpse a few shortcuts that could cut down on Reagents needed for a test. Realizing that the corresponding result could be more or less accurate. Thought it...

Shortly after closing my pool for the winter I got a gallon sample of pool water so I could play with my testkit which I was to get soon. Didn't order right away and I just got my TF100 and was starting to play and the first thing I did was the OTO for FC. It read zero. Where I am confused is...

Just got my testkit and was wondering about accuracy needed using the bottom of the label and top of the label as the guides for how much water and reagent. The reagent will be consistent due to the label heigth but it appears my label is like 1/8" inch low from making a 50/50 ratio for the...

I have had the pleasure to work with a few life coaches and they all say a big part transitioning from dreams in your mind to success is the accountability of your actions to get from "A" to "B"....This all ties in after defining what’s your life goals and what you are willing to trade for it...

Just replied to another post regarding cost of chlorine and decided another chart I made last year may be helpful to others. I got the impact of chemical use and qty to move FC from the Pool Calculator. At the time I didnt realize you didnt need to shock weekly but its still a quick snapshot...

Was at a newer hotel over Thanksgiving and noticed some nice small bubbles and a small spray comming from a return going out about 3'. At first I thought it was just coincidence the "low speed" on the returns were working out to do this, but by curiosity I found another jet and no water was...

Have some questions on items being sold as part of winter kits....I've read posts on this forum where people just shock, also some add algaecide. Am curious what these things are suppose to do??? Seems there are items being added, anyone know the contents and logic behind what the kits are...

I have a new pool (to me) and had drained the pump/filter, cover, etc several weeks ago. I just today got around to putting pressure in the lines to put in the three plugs and am concerned about how well things are sealed....I put the plugs in the return lines and I still have bubbles comming...
