HI
Just need a bit of general advise,
Im thinking of installing a trickle tower to my pond, which is gravity fed, cloverleaf CL2 filter, ( 2000 gal), Researched on tinternet & decided i can make my own out of 4 plastic storage boxes i can get from my works, just need to buy piping & media,
My question is, Is it best to pump water directly from the pond to the tower & at what rate or tap off from the return pipe from my pump to feed the tower & in doing this will it affect the return water rate.
Hope i said that right !!!
Anyone using a tower ?
Any info much appreciated

Hi
I diverted my return from the filter straight to my home made T/T,
which works fantastically well,It would affect
the flow rate to your pond if you Teed into the main return as well,as water will always take the shortest route,where possible.My only concern when I did the modification was the circulation of the water in the pond,it works fine for me with only 1 return.

i have purchsed 2-3 inch koi's for rearing on yesterday. they are in a tank with salt added. today some are swimming near the surface and they seem lerthargic and dorsal fins are down. ammonia is ok, water temp is 14 and i am aireating. any ideas?
Posted on Nov 4, 2009, 7:47 PM from IP address 84.70.133.128
Such a difficult thing to answer but a few thoughts as :-
What's the 'tank' water volume ?
Presume you have a mature & appropriately sized filter on the tank ?
Do you test for ammonia, nitrite, pH, kH as a minimum ?
What temperature water did the koi come from ?
Salt in the water is usually used to assist with wound healing by
helping with osmosis problems or to help alleviate nitrite poisoning.
Just wondering why you have salt in the water & have you measured the
salt concentration to make sure it's not too high ?
Of course, the fish could be carrying some parisites etc and
the water quality isn't an issue? You'd need a microscope to check this.
So many possibilities and any one small thing could be an issue.....

were are just about to embark on a new pond my wife would like it tiled but i am unsure if it is at all possible and wondered if you had any thoughts or ideas on this subject
Posted on Oct 25, 2009, 2:07 PM from IP address 90.195.200.51
hi nigel
in one word, dont. the reason why is as follows,
the tiles will become coverd in alge and will not be seen.
the tiles will eventualy peel away from walls causing leaks and will be imposible to repair,so you will have to retile the whole thing,
also, the grout will crack if tiled to block work becase of expansion and contaction.
it is ok to tile a pool if done by a pro but a pond i would say is a big no no.
i recomend you build a pond with a fiberglass liner up to the water levil and then tile the top which is out of the water to give it the effect that it is a tiled pond,
i am not saying you cannot do it, but the maintenence on this type of pond could end up being expensive and futile.
have a look at some of the builds on this site to give you some ideas.
if you need more info or help or advice give me a shout.
i have built many ponds in my time.

Hi Keith M. I have a Nexus 300 and an Easy, I find the Hi-blow 80 type air pump the best, I also drill out the air holes in the air ring in the Kaldness to half a M/M to cope with the air-flow. Keith H

Hi, Apologies for not being a regular poster on this site, but I'm looking for some advice or help. I have 3 small carp, not sure if they are Koi's, stuck in a tank in my kitchen. They deserve better as they are growing to big for the tank, I'm looking for a good home for them. No charge and I'll deliver to your door, I just need to know that they will have a pond to grow up in. The first is about 8" long dark green in colour with large scales. The second is about 6 ", silver with red/orange markings. The third is about 4" all orange,but it has a mouth which is pushed over to one side. As I have said they are free to a good home. Can anybody help? Cheers. Sven

Hi Alfred, I have a Nexus and I use the foam block in the exit port, supplied by EA, it costs around £12, I take it out and clean it daily with my hose only because I am home, it will last longer without cleaning, my water is very clear. Keith H

Wondered if anyone can help. I have a cloverleaf cl2 filter, The trouble is, i have been told that if you have it on a gravity fed pond, pump return, you have to block up the centre overflow pipe in the middle of the last chamber, when i do this i find that the pump empties the last chamber and i then get an air lock in the return piping.Therefore no flow through filter.... if i remove the bung the last chamber fills up to a level just below the rim of overflow pipe and things run ok, Now, when it rains and the pond fills up excess water fills last chamber, goes down this overflow pipe thus eliminating the alfragrog filtering in last chamber.But plenty of flow in the filter. Any one any ideas of the correct way to use the filter or other ideas ?????
Many thanks

Hi Folks, I,m thinking of using an easy pod on my skimmer return for filtering out fines as it seems much cheaper than a beed filter. I don,t run my skimmer 24/7 so I intend it to run purely as a mechanical filter and was wondering if there are any problems with this such as good bacteria growing and dying back or any other snags. Thanks.

hi, im in building game myself and i would say no,u need to brick concrete block flat on flat upto ground level that where all the pressure ,then cantalever blocks and do a cavity with foam fill above floor level ok good luck

Actually, I don't see why you can't use thermalite blocks above ground. Lateral water pressure decreases the nearer you get to the top so it rather depends how much of the pond is above ground. If it were me, I'd be inclined to beef up the thickness of the GRP and take it up over the top of the blocks to form a wide flange. This should proved plenty of lateral stiffness so that you're really only using the blocks as a former and something to fix your external cladding to.
I'd be more worried about the effect of polyester resin on insulation foam if it is expanded polystyrene or styrofoam.
Just a thought.

Hi, i am planning on building a pond. Would it be possible to build a free standing pond from railway sleepers if i bolted them together, and then used a pond liner ? Do you think it would hold from the pressure from the water? Mant thanks Andy

hi, firstly great site, myself and my dad have kept koi for a few years now,ive just bought a house of my own and am planning to build my own pond,size 12ft by 8ft by 5ft depth,after visitng coldwater collection i noticed ken ,instead of having a domed bottom drain,he had a flat grid fitted flush to floor,i was planning to run a 110mm pipe to middle of pond with a 90deg swept bend and fitting a flush floor grid over the top instead of a adjustable dome like standard drains,will this cause any problems such as pressure to my vortex, pond will be 3000gallons and fitting a 2600gph pump with adjustable regulating valve,just wondering if this will work because i wont have dome (mushroom) over my drain. be gratfull for your advice many thanks
Posted on Jul 5, 2009, 10:45 PM from IP address 94.196.58.22
The only person I know not using a dome on their bottom drains
is Maurice Cox at Koi UK. The reason is that he sometimes uses
a seine/drag net to collect his fish and using a domed drain
would snag the net so Maurice uses a flush fitting grid instead.
However I understood that the dome creates "side-suction" that
most need to suck all muck down into the drain.
I suppose it depends on the pump flow rate you use to see if
a grid works or not to give your system enough suction.
Good luck

Hi folks, I have a pond full of sick fish that I have treated with one dose of potassium permanganate, two doses of chloramine T and one dose of fluke M, after each treatment they seem to improve for aday or so then go back downhill. Now they worse than ever with a few showing signs of fin rot/bleeding, another has either adeep cut/ulcer and a doitsu showa has turned pink where it was pure white.They are now in the one spot all pointed towards the wall.I was wondering if anyone recognizes the problem or had it and really what was the fix? Thanks for your help.

Some thoughts as you haven't given any details of your set-up or maintenance regime.
a/ Have you introduced new fish recently ?
b/ Is your filter set up sufficient for your pond size & fish loading ?
c/ Do you have sufficient air going into the system ?
d/ Could you have some contamination going into the water ?
eg Metals, chemicals, garden run-off, acid rain, lime from concrete/stones etc etc ?
e/ Do you do regular partial water changes with dechlorinated water & flush your filter ?
f/ Is the fish health problem recent or a long term thing ?
Dosing your pond with all those chemicals may have made things worse if the fish are
already having problems if you did not do a scrape and check for parisites under a microscope.
Good Luck

add salt to your pond to a ratio of 3-4oz per gallon mix salt in a couple of buckets with warm water,add this over a couple of hours ,buy yourself a salt meter much easier to maintain correct levels, fish will survive in these levels of salt and its always in water until you change water, then just add more salt to maintain 3-4oz per gallon,MAKE SURE U USE CORRECT SALT CHECK BEFORE BUYING,good luck, i been there and finally and luckly after losing few fish have come good.
