I think I remember reading that particular plants were especially good at
removing phosphates. Might be something there worth researching?

Hi,

I've got a problem...............


my water is HIGH in phosphates, very high..

I want to put a filter on my tap water to facilitate water changes without
putting all that phosphate in....I'm fed up putting in the phosphate
removers to my filter - I want to remove at source (OK rant over)

Any suggestions on a good filter/RO unit to go for? I have a 1500 litre tank
and want to do 15% changes every 2 weeks.

tia,

Sky.

I bought one of these and have been quite happy with it.

Hmmmmmm.

First, do you know how the phosphate got in there? If it's from fish food,
yet your tap water is low phosphate you need not filter the tap water! What
are you keeping in the tank?

Let's suppose the issue is the tap water (and by now you'll have guessed
that you should really test the tap water!). The economic choice is between
buying RO at your local shop, transporting it home and changing water. Or
buying a RO filter and putting it on you domestic water supply.

You are changing around 50 gallons every two weeks - at my local shop that
would cost £25 and weigh (literally) a quarter of a ton so your water change
would require almost military planning (but at least the water comes pre
heated where I buy it).

If you buy a RO you've got a whole host of other problems not least storing
50 gallons and what to do with the 200 gallons or so of waste water that
you'll have to lose. Even so it should be a lot cheaper.

However, I think you should first work out a strategy for minimising the
phosphate input before dashing down to the shop to buy the RO unit. It's
just I'm having difficulty with the idea that the phosphate in your tap
water is so high as to cause a problem that Rowaphos can't fix without there
being a pretty serious problem as regards the Drinking Water Regulations.

The only other thought I have is that less frequent BIG water changes are
more effective at changing water chemistry that multiple small ones, so
provided your tank can take the strain you might be best advised to do three
or four 30% changes at weekly intervals to sort out the current problem and
then revert back to your usual pattern.
