Weed and Algi #1
Hi all.

I had problems with blanket week last year, not so bad over winter, but getting bad again now. I've been pulling loads out each weekend.

I've tried a couple of treatments, (bio) and they have both started to make a difference, then it takes over again.

I know the conditions of the pond are practically ideal for the weed (and fish) and I'm not prepared to spend a fortune getting nowhere!

I've heard that Catfish may help by consuming the algi and weed, is this true? Personally I wouldn't have thought Catfish and blanket weed would get on.

If anyone knows please let me know. Also what variety, how many per k litres?

Thanks.

PS, please also Email tull@idcodeware.co.uk I don't get here often.

Cheers.
Tull.

Re: Weed and Algi #3
I suggest you try barely straw bundals you can buy it either ready bundled to suit the size of pond or in mini bales that you can stuff into tights or similar and anchor to the side of the pond. This will help but really you need a lot of plants to take up nutrients and create shade on the surface blocking light getting to the algae. Lillies work well for later in the year (they are only just shooting) but at this time marginals casting shade help

Re: Weed and Algi #4
to be honest azolla will probably work better than lillies, but it grows lots

Re: Weed and Algi #5
Thanks for getting back.

The pond is around 4 x 2 meters, and 2 foot deep at the bottom end, raising to nothing at the other.

I have loads of pond weed, good airator, another similar plant that usually grows and sits elongated on the surface (not sure of the name) and a pigmi lilly. Of course all of these were cut back and small at the moment.

I think the major problem is the sun light, it gets the early morning and mid day sun.

I've tried barley treatment and barley bails, they do nothing. I'm currently trying another bio treatment, but I have a horrible feeling the pond is just in the wrong place, and I'm not built for digging!!

Cheers,
Tull.

Re: Weed and Algi #6
any sort of filtration? or is it only the plants keeping the water safe? how many fish are in there and what types?
