    Filter system has explosive purge of air

    Thanks everyone - I'll take a look this weekend and see if I can get to the bottom of it. I once saw a recommendation to use a 'smoke-box' to create smoke to diagnose the issue. In other words, use the smoek to see where the air is getting pulled in. Also, I'll check which grease I'm using -...

    Filter system has explosive purge of air

    Thanks so much guys. Water level is right to the top of the skimmer box, about 10mm from top to be exact - not sure if that is 'right', but certainly not low. Interestingly though, the level is above the small 50mm round screw plug on the side wall of the skimmer box. I'm not sure what that...

    Filter system has explosive purge of air

    So my pool just started doing this thing in the last few days that when the filter stops all the water drains out of the filter-system - the clear barrel with the salt element in it empties in a few seconds and you can hear all the rest of the water in the pipes disperse, then there is an...

    Mixing Zeolite and Silica Sand

    Mixing Zeolite and Silica Sand

    My sand filter has 5 bags of zeolite in it and is only half full. It was originally about 3 quaters full with silica sand but zeolite is so expensive i didnt buy enough. Its been running for 6 months without issue but filtering is not quite as goid as i woukd like. Im thinking of topping up with...

    Troubleshooting poor flow pressures

    I think you are 100% correct with the overflow. It is exactly where it should be for an overflow, roughly about 2 inches below the top. I'm fairly sure it will not have been plumbed in by the previous owners when the pool was fitted, hence the cap is on. That's for the tip about the smoke -...

    Troubleshooting poor flow pressures

    That's a great tip - will try the running-hose troubleshooting trick. Unfortuantely my pool equipment is in my shed, so soaking the floor is a problem, but worth it if I can track the issue above ground! I big part of this for me has been learning the plumbing for my swimming pool. As far as I...

    Troubleshooting poor flow pressures

    Oh man. That sounds really worrying! Could that be combined with excess water loss then?

    Troubleshooting poor flow pressures

    This is driving me mad and, to me, it would appear to defy logic. I used to have a pool/system that would happily run an automatic cleaner (aka Baraccuda, aka Kreepy Krawly) on the end of an 8m hose. Now I have a system that hiccups, splurts and farts if fit a few metres of hose to the skimmer...

    New filter - can I reuse Zeolite from an older filter that had Mustard Algae?

    Thanks for that. When you say 'good quality sand'. What kind of sand are we talking? I did look at a few posts from TFP over the last day and most of them were comparing Zeolite to 'sand' without declaring what was meant by 'sand' - although on a few occassions it became clear that it was...

    New filter - can I reuse Zeolite from an older filter that had Mustard Algae?

    I'm not sure where I got that information from about algae living in the filter - it was in a forum whilst I was researching the Mustard Algae. I'm sure it must have been another forum though, not TFP ;-) That's interesting what you say about sand working just as well as Zeolite. I'm...

    New filter - can I reuse Zeolite from an older filter that had Mustard Algae?

    Hello TFP folks. I have been fighting a bad case of Mustard Algae for a few months now. I managed to get mostly rid of it after a SLAM, but it never truly disappeared. As it turns out, a leak in my fibreglass sand filter was causing filtering issues and has finally caught up with me now so I...

    Question about SLAMing

    Thanks so much. I'm just about to go to the shop to buy chemicals and will work on the pH and CYA levels first before adding liquid chlorine. Just wondering though, is there somewhere on this site that will tell me what amount of liquid chlorine to add based my current FC level? Sorry if it's...

    Question about SLAMing

    I'm about to SLAM my pool. I'm very new to the process having never done it before. I have a salt-water pool (details in sig), but I think my CYA/stabiliser level is virtually zero (probably not had any added in the last year). I have just received a good 'test-all' kit from Clear Choice Labs...

    Having filtering issues - cannot remove fine sand from the pool

    Great news - my clear choice lab kit arrived today, so I will be working on the pool this weekend. Yay! I backwashed my filter in the last month. Didn't take note of the PSI difference before and after, but it didn't make much of a difference in terms what was going on in the pool, ability to...

    Having filtering issues - cannot remove fine sand from the pool

    Sorry for delay, it was nightime here. I've just checked this morning and yes, it does just "poof" away into murky water. IE you can't actually pick it up and hence it's probably not sand. Wow! Looks exactly like light brown sand but isn't - - - Updated - - - Thanks for your reply - I will...

    Having filtering issues - cannot remove fine sand from the pool

    Hello. I've having a real struggle with my pool for nearly a year now. I noticed about this time last year that when I was vacuuming up sand from the bottom of the pool that sometimes it would come straight back out of the jets when the what comes into the pool. Also, confusingly, sometimes I...

    White bits in pool, probably from Chlorinator?

    Ooops. I've just seen all your replies saying don't go to the pool store, just AFTER I got back from the pool store!! Actually, I went to 2 to get two separate test results and they appear to confirm what you told me. Results below. The good news is that it didn't cost me anything. One of the...

    White bits in pool, probably from Chlorinator?

    Thanks Kiss4aFrog - I've started my signature but as you can see, I've got to fill in the dots once I get home and check out the equipment. Thanks JoyfulNoise - I've read a good portion of the Australian Test Kit discussion you pointed me to. Looks like the Clear Choice Labs option is my only...

    White bits in pool, probably from Chlorinator?

    Hey folks, this is my first post here. I've owned pools now for about 5 years - in that time I've had 2 saltwater pools in 2 different houses. I'm no expert, but I've picked up a few things along the way. One thing that has contantly bugged me in both properties is that I almost always...
