my dad has about an acre sized stock tank and has a pretty bad problem with hydrilla. we have tried different chemicals, they do great but only temporarily...was thinkin about carp or tilapia? any suggestions/experience would be greatly appreciated.

Grass carp. Tilapia are plankton/algae eaters so I don't think they'll make much impact on hydrilla.

definitely ask the officials that stocked the carp in Conroe...

JK...but grass carp LOVE hydrilla.

Back home they use chicken poop ( liquid form ).. I don't know how long it last though.

i figure a pond that small we could control the carp population pretty easy if they got out of hand

yep

I've gotten a lot of good pond info in the pond section of this forum... Meadowlark knows whatsup

i hate grass carp

Ask TPWD how they screwed up Conroe.

A buddy had a beautiful bass tank with grass in it,,, clear water. He put 10 grass carp in and ruined it. Visibility is about 3" and muddy red.

add cypress springs to that list

You can order grass carp for TPW, they have to deliver it to you pond though. Hydrilla has to be introduced, chemicals are only a quick fix. Sterile Carp will not completly solve the problem. because when they die, it will come back.

I think some of those got into Sandlin through the blow hole.

You sure about that? I wasn't aware that TPWD sold Triploid Grass Carp. I know you have to have a TPWD biologist come out, look at your lake and recommend the proper number of grass carp, for which TPWD then issues a permit. But the actual purchase of the carp is done through TPWD approved fish farms, not TPWD themselves. Or at least last time I checked.

That may be, My father in law did this in his pond. Someone said he could only have 3. I know he had to go thru TPW to make the purchase.
