Baulking at Seagull prices I've put a 2.5" x 10" filter housing with coconut filter direct from tanks. Seagull claim to remove similar to coconut but also "microbiogical". Surely I would just need to put a purifying tablet in my tanks to get the same protection? My setup (handling 8l per minute) cost £40 in total. Am I correct? Or just a cheapskate.
 
We use a 10" 1 micron filter in front of a 10" carbon filter. The 1 micron filter keep any sediment from contaminating the carbon filter so it lasts longer. Water tastes good. We used to buy the little Whale filters but they cost too much.

I just used a 1 micron carbon (coconut) filter. Vyair said flow would be fine with that, though may drop off at end of life. Given that I'll change every 6 months (the watermaker project moving towards completion needs chlorine free cleaning water or the membranes will be damaged) the cost of £9 per cartridge isn't going to break the bank.

Yes, water tastes good. No smell at all.

One on the lists of jobs for me is to drain the water tank and clean it. I suspect I have sediment in it. The 1micron pre-filter get mucky pretty quickly. By comparison the carbon stays clean. We only put RO water in the tank, never from a tap, but we have put rainwater straight in. I suspect this is where are sediment has come from. We will install a filter on the rainwater system once we have cleaned the water tank.

Pretty much the same, except with 5" cartridges.
One question I asked myself: filtering through carbon removes chlorine, so how long can that water remain "safe" inside a tank, especially in hotter climates?

We fitted a GE Nature Pure filter system this year and it has been transformative. The water flow is slower, but oh my word, it tastes amazing and no more fizzy teabags. Happiness abounds!

I have wondered this myself. For this reason the only water that goes in the tank is RO water. We UV filter the RO water on the way to the tank such that it should be bug free. I have only ever heard of people getting contaminated water from filling up alongside. If you can keep the tank bug free then temperature shouldn't make such a difference
 
No, you certainly do not want to remove chlorine from the tank. You want to remove the chlorine just before the tap.

a. I worked in the field and written a few articles. A summary is here:

b. You buy cartridges for the 2x10 that will rival the Seagull. Look for NSF 53 ratings. Doulton of the UK makes some too.

I love that the 2x10 housings take some many quality elements. Personally, I like the Pentek Floplus 10 0.5 micron carbon block, but I don't know about availability

I ditched my Seagull 4 - too expensive.
 
Glad to know that my approach is not just cheapskate but works. I will be keeping some backup chlorination for the tank. Thanks for the link to the article.

I need to fit a filter to my water system this winter. Could you share exactly what you bought and where you obtained it from. How did the fittings work, as the ones I have seen on Vyair website dont seem to have the sort of fittings which you can jubilee clip a plastic hose to.

I got the bits off ebay or amazon. Picture has male/female90 degree 1/2bsp elbow into which a 15mm push fit connector is screwed. Into that goes a plastic 15mm to 12mm hosetail. I am sure it could be done more elegantly but I needed to get the bends in and used the bits I had been collecting for the watermaker project.
