:confused: Hello everyone, I want to install a sand filter in a pool that is 18,500 US Gal. or 70,000 liters. I was trying to find the specs (with easy numbers) on the Hayward S244T sand filter effective filtration area or filtration capability to check if this model would be more than...

Hi guys! Hopefully I can get a little help with this: There is one pool that has: Pump ---- STA-Rite JWPA5FL-A 1.5 HP Filter ------ Interwater Model 190TS The filter however is too small and needs to be replaced as it 's causing the pool no to be cleaned properly and black algae...

Hi all, So we are just trying the product Black Alae Killer (Leslies) step 4, for the black algae pool we have.... long time fighting and controlling it... The pool owner brought this from the US (we are in Mexico, in Baja) together with the Fresh and Clear step 3 Oxidizing shock... Don't...

Hello all, Could anyone help me out knowing what would be the recommendable model/size, maybe Hayward?, to replace a current sand filter that is too small for a 11,100 gallon pool? It is a SWG pool... It is a 180TS with GPM of 40, brand "Inter Water" ? The pool has a black algae problem and...

Hi all, haven't post in a while but keep reading when I can. We took over a pool almost 18 months ago or a little more. First, it had black algae on the walls, not much, but it was obvious and present, but more important, it didn't matter how many times we brushed (with nylon or metal), or if...

Hi all, One of the pools caused itchiness to one guest some days ago, but the strange thing is that the pool levels were ok.. 8,500 gallons bleach pool FC: 5 pH: 7.5 TA: 110 CH: 250 CYA: 70 Do you read anything wrong here? I need to add one thing that I am not sure if it could be the source...

Hi all, Last November 2009 -January 2010 we had some black algae in one pool. The pool walls are somewhat pebbe type or like we say it here "washed sand walls". A year ago, we shocked the pool following some hints you have over here and it worked good as the algae kind of dissipated. But it is...

Hi all. It has been a while since I last posted anything! One of the Aqua Rite SWG seems not to work at all now. Before it had also trouble with the cell readings (cell is bad too, but the owner doesn't want to invest on the fixing). Attached you can see a picture from last year when the SWG...

Hi all, On the last pool on the signature (a smaller pool), I found this white marks, but can't tell what they could be... Do the pictures help you identify what could it be? and how to remove them? These white things are located on the edge of the spa... also in the pool ground there are...

Hi all, In one of the pools, the skimmer / main drain diverter (as shown at the visual encyclopedia from the PS) pool-school/visual_encyclopedia, seems to have trouble working as it should. Looks like the "floating" device from the skimmer sinks and gets stuck once it is placed in the skimmer...

Hi there, I had to check one of the recent pools (not added yet to signature) to check the hot tub and pool lights (one light bulb on each part). I removed the bulbs and shoke a little the bulbs and could hear something loose insight as when they need to be replaced. I replaced the bulbs but...

Hi there, There is a new pool (not added to the signature yet) which has a couple of stains (pictures attached). Small pool. Please let me know if you need any extra info. pH: 7.8 FC: 2 CH: 1,000 TA: 60 CYA: 0 Salt: 4,100 (strip) Salt: 3,000 (Aqua Rite computer) The stains look like...

Hi all, The pool labeled CL on my signature went recently through a new placement of the automatic fill. This was done by some contractor hired by the pool owner. The are important questions to be made here, maybe you can help me out figure what the answers could be? The CL pool is an...

Please vote! Thanks! Hi guys. I know it is hard to know specifically what kind of filter is best sometimes but I am looking for overall votes considering: - Easiest way to maintain (time efficiency, the quicker the better) - Less expensive to maintain (invest as little as possible on...

I have been reading about calcium scaling on the forum and other places, but here (this area or surroundings) it is very difficult to find anything related to the Calcium Hardness indicator.. (chemicals to balance this).. Does anyone know any other chemicals/products that will help raising or...

Hi, i have noticed that on two pools (SG and JK on signature) the pH levels are hard to maintain at 7.5. They usually go up to 8.2 on every "service" we make on them. We get there, we check pH, we adjust with muriatic acid to 7.5 and then come back in three days again just to find that the pH...

Hi, in the pool labeled as GM on my signature, I noticed a couple of weeks ago that after doing some backwashing and cleaning the sand filter and after the floor where the water was running got dry, there was some sand in place kind of redish. Pictures below. It this normal to happen? Could it...

Hi all, The CL & CS pools (on signature) have the item shown in the picture (sorry for the blurry pic, cell phone). What are your comments on this item? Does it works ok? works so so? How often has to be serviced? It is the first time I see these installed. One is installed near the pool pump...

Hi all, Yesterday we were making some tests on the CL pool (signature) trying to heat it up for today.. Started 5 pm yesterday. Pool water temperature is these days around 20ºC (i think it is like 68ºF) so it's cold compared to the 24ºC+ we usually have after March-April. We left the heat...

Anyone has idea on this question maybe? http://www.troublefreepool.com/post145805.html#p145805 Thanks!

Hello all, Could anyone tell how bad or recommendable is to have the pool equipment enclosed or under some sort of shade? If it's enclosed, would need to have enough ventilation and would prevent direct rain and sunlight hit on the equipment. But if it's only a shade, it will mainly cover it...

Hi all, One of the pools (SG on my signature) it's super heavy loaded with CYA and CH. It has an Aquarite system with a DE filter (picture attached). The house will be empty from today until December 2nd. (just got the news).. so I wanted to try to drain some water to start balancing it, but...

Hi, I found that one of our "pump nets" is damaged. Do you know where could I find one of this? It would be my first replacement for one of this, so don't know what should I take in consideration to find the proper size, dimensions of the "net"? (the one that goes beside the pump) Picture...

Hi, I just tested the pool labeled "SG" on my signature and I am in shock... :shock: Well I am in shock as I never in my super short experience read this results... These come from an operator (no real knowledge as I can say) on pool balancing.. just plumbing knowledge... and I believe he...

Hi again, I am still getting some data on where to get the washing soda or soda ash for the other pool I posted about (GM on my signature). This is another one. Just read again all of the pool school and some posts in the forum but have the following questions... maybe somebody could help me...

Hi, Some days ago I was talking about one pool (the one labeled on my signature as "GM") with some sort of algae problem, but principally a problem on the walls where the algae seems to be very difficult to remove. One suggestion we got was to drain all the water from the pool, and then use...

Hi, Today we tested another of the pools (in my signature marked as GM) using a "borrowed" Pentair test kit (pH and Chlorine only). This SWG pool is one I commented in other thread that had some algea problem and I was thinking/asking here if it could be because of having very low "dirty"...

Hello, I am making my final research for buying the first test reliable kit for ourselves, so once it arrives and we test it, we can start ordering more (little kits for now, could be up to 5 max at once). Made some research on the FAS-DPD test kits and have one, maybe, technical question that...

Hi everyone. It seems we have a little problem with one of the salt water pools.... (just came back today Oct 7th from checking this).. As it is a new pool we are taking care of, our operator reported that after doing the regular cleaning and scrubbing and checked the pH level and chlorine for...
