I wouldn't, they always give off dust made of fine glass in the air, and that would end up in the water. The polyester insulation I have doesn't give off any noticeable dust, so I'm happy to filter system water through it.

Ok bugger. I read the box of my filters, they are rated to 15000 litres. I have 2. Looks like the shop was being quite optimistic thinking that would be good enough for a 50 000l pool. Might need to invest in another one or two...

I know I found it in the bin luckily the day before the recycled went out. Have brought this to the attention of the shop, they blamed miscommunication (a whole heap of BS because I distinctly remember asking repeatedly , will it cope with a 50000L pool in full sunlight with 100 plate sized silver perch and be crystal clear??? Yes yes yes. Anyhow they offered me a 75 w UV at a discounted rate, followed by for free after my phone call. That will apparently clear a 100000L pond. They promise the biofilters I have will suffice for biofiltration. I pick it up tomorrow and will report on my progress/regress. Luckily solar panels are getting cheaper, I need to bump up my grid connect because of this little project.

With the caveat that this might not be good advice (im new here), if i were trying to kill al the algae in the pool, id be getting a few pumps and a few big ass UV inline filters and trying to get my entire pool volume through the inline filters as often as possible. Doing this should kill the algae, and with luck within 4 - 7 days the pool will be clear.

Seen 55W inline UV on ebay that reckons its good for 25,000L pools. Maybe you need a few of those along with the pumps.

Hi ark always good to get advice. I already have 2 x 18 w UVs and a further 75 hopefully will fix it. Apparently the 75w is quite long and my pump is rated 30000 l per hour at 2 m so should see the entire volume done every 2 hours. Really looking forward to seeing the floor of the pool again... And what lies there.

Then my next project is to rig up the pool water to irrigate my whole orchard and soil veg patch. Then I plan to simply refil pool water using the dam rather than using dam water to irrigate trees and then bringing in fertiliser.

Regarding image resizing I downloaded iresize. You then just make sure your images are reduced to max 800 w, 600 t. Take them landscape for better resolution.

It's been 2 weeks since I installed my super UV steriliser. The pool greenness didn't disappear but got darker and darker. I have a feeling that the algae is dead but is not being filtered out. I was toying with the idea of draining again but woke up at 4am and sat upright in bed and thought what if I put a stocking over the basket of the existing pool filter?

So I did just that and its starting to look like its improving.

The guys at the aquarium said I should not use the pool filter because its not designed for larger solids but I reckon I could use it as an adjuvant? I will post a pic in another week or if I see radical improvement before. I imagine I wouldn't need to run the pool filter too often. I hope now cause its a power muncher.

it does look like it's dying out..
you could use a floculent.. personally i'd be a bit hesitant, it'll settle out.. and the added benefit is that once the algae is dead, it gives off some chemicals that actually decrease your chances of another algae bloom.. (as long as you're not way overstocked)

I did run my pool sand filter a couple of times, You may need to back flush every time, as the filter will get rank with all the algae and crap sitting in it going anaerobic.

But in the above photo it looks like a pond to me!

pool still green. This is just crap. I have over 100 watt of UV, 2 large filters, nitrates are 0.

I emailed some geezer on ebay who is selling the 75 watt uv sterilisers for $200. I told him about my system and he reckons the water is flowing too quickly through the UV, not giving it enough time to kill the algae. So today I slowed down the flow (possibly putting load on my pump), will see how that goes and if it helps, I will make a T and divert 1/2 back to the pool to ease pressure on the pump. If it doesn't work I'm tempted to buy another 75watt UV and run it in series with my other, making it about a 2 meter tunnel of 150 watt UV.

Obviously a pretty bad case scenario at the moment with long days and very warm water but nitrates negligible so it will get a whole lot worse by this time next year.

Kids still happily swimming in the thing for hours, no sore eyes and is a big adventure for them. However I keep looking at natural pool websites and drooling at how crystal clear their water is. Found a public pool in Germany. It can be done (its getting a little expensive - although I've saved approx. $360 in chemicals at this stage). My husband is giving me one more chance before he tips chlorine in. Help!!

Not a great deal of useful info on the net, all commercial stuff with phone numbers and none in Australia.

I'll mention barley straw again. It produces an enzyme just like the one algae produces when the bloom dies off, killing your bloom. It would probably take a lot of it, but it is still an option.
