Pond filters

Is anyone using the Laguna pressure filter system?

I'm thinking about replacing the no pressure open tank filter that's inside the garage wall with one of these click here outside flush to the ground.

I've used a Hozelock pressure filter in the past but found that it blocks up to easily and needs cleaning every couple of days which is a pain. I want to know if the Laguna easy clean & flush claim really is 'easy & quick'.

I have a similar device with 5 foam elements, needs stripping and cleaning about 3 times a year,"a loverly job".

Thanks Fruit Bat /\0/\ i didn't want to buy one and find I still have to clean the foam filters out even once a week.

and clean them once every couple of months in the summer, and once or twice during the winter.

Be careful with the water diverter switch - it has a tendency to break off in your hand in very cold weather.

That's my Bank Holiday job now, renewing the filtration and making a higher waterfall. Sod trying to get to the seaside.

I got the bigger filter with the bio bits in the bottom and it's just clearing up nicely from the disturbance. The blackbirds were waiting on the garage roof all afternoon as if to say 'get a move on, it's bath time', the fish seem livelier and the toads have reappeared, from where I know not.

I'm now going to enjoy a Glenmorangie at the side of the new stream. I named it 'The Glen of Tranquillity when I first built it, so Glenmorangie it must be while I wait to find out if Brumas is going to post a card from somewhere I know for a change;)

I'm getting quite a bit of froth on the pond surface for the first hour or so in the morning (it's controlled through a central heating timer switch).

Is this until the filter becomes 'live' with the biological media and foam elements being new, or can it be the UV killing of the micro algae? The water went green over a month as the old UV failed and the old filter box was leaking in the garage, which is why I renewed with an outdoor one.

I should add that it's not a bubble bath level of foam, it's a single layer of bubbles on the surface that gives the impression of foaming. When I put the flaked food in, it seems to break the surface tension enough for the bubbles to disperse for the day.

I could leave it on all the time until the filter becomes fully live I suppose, but I want to know why it does it:(

I often see foam around this time of year when there is a lot of frog spawn in the pond. Not so much this year as there has been far fewer frogs.

Just a thought.

I've got toads, it could be them as I've had quite a lot of toad spawn that the fish quickly ate.

I’d love toads...I’ve never even seen one! But I do have newts...and herons that are a real nuisance in our area. Our near neighbour lost 15 fish to one the other day.
