My pond diary

9435

September 2010
I had a pond lying around and collecting dust. Cleaned and set it up only to realise it had a leak. I patched up the cracks with cement and painted it with water block. 4 coats later it was ready to be tested. I let it dry inside for about a month. The pond holds approximately 100 litres.

October 2010
I set up the pond outside in October 2010. I had a 50litre/hour pump which I connected to a three step waterfall. Within 3 weeks the pond was pea green. I emptied,cleaned and refilled but again within 4 weeks granny smith apple green.

November 2010
I now realised I needed to get some sort of a filteration system. I studied the filteration thread by the Proff on TASA and done more research. (at this stage I had no knowledge of fishkeeping, thanks to the thread it took me out of ignorance. I learn everyday). I concluded that I needed a filterand a UV light. Problem was, most pond filters were to big and too expensive (I was currently saving for my current tank). So I decided to do a DIY contraption. I gave my fish away and the pond layed green. I decided to tackle the situation in the new year.

January 2011
1) I purchased a second hand 15 watt UV Filter from the classifieds.

2) I went to craze store, bought a container 30cm high with a lid.
3) Made holes at the bottom of the container with the help of a lighter. The holes were about the sixe of a 1 rand coin.
4) I filled the container with stones at the bottom. Than cermic noodles and bio balls. Than activated carbon in an old stocking. On top I added filter sopnges.

5) I connected my 50litre/hour pump pushing the water through the UV light first and than through the bucket filter

After using the DIY FILTER MY POND REMAINS CRYSTAL CLEAR...AMAZING...I do water changes evry 2nd week.

February 2011

In february I set up the pond again. I introduced
1 x fantail
1 x shubankin
1 x sarasa commet
1 x commet
1 x male guppy
2 x female guppy

The guppies started giving birth. I use to transfer the guppy fry to a 50 litre grow out tank. Once big enough I brought them back to the pond. The reason I done this was because I feared the goldfish would eat them.

May 2011
After one cold Highveld night I awoke to dead guppies. I had seven guppies and all were dead after the first major cold spell. All I had left were the 9 guppy fry in my grow out tank. I KICKED MY SELF FOR NOT BRINGING THEM INSIDE FOR THE WINTER. Well this answers the question? Guppies dont survive the highvel winter in outside ponds, However they thrive in summer.

June 2011, July2011

The gold fish are all alive. In winter I have been feeding them 1 to 2 times a week. The pond remains crystall clear. The filter runs for about 4 hours a day. I maintained good clearity from the introduction of the filter to date.
Thanks fo reading. You can check my album for more pics. I hope this was benficial.

nice man.. I love a good diy!

I did something similar instead of having holes at the bottom of the filter, i put the pipe at the bottom of the filter and let the water filter upward so it doesnt get clogged as much.. I had green water for a yr, left the filter to do Its thing and had clear water ever since..every year when i clean the filter the water goes green temp before going crystal clear again..

Nice little DIY,but although you have crystal clear water... you dont have any form of Bio filtration - the bacteria that breaks down the fishes nitrogenous waste products needs a 24/7 supply of oxygenated water...switch it off for 6 - 8 hours, and its all gone - takes about 6 weeks to build up again...

You might say that everything is going fine,but consider this: Its currently winter - the biological activity in your pond is very low,so very little Amonia is being produced - this will all change with the onset of Spring - warmer water,increased feeding from your goldfish (Thats grown in the mean time,producing more waste...) - rather leave the pump on from now - you will hae a biologically alive filter,ready for the new season...

Another little crit - get hold of some batting or filter floss... put this as a first mechanical form of filtration - bio - bacteria needs clean water to perform at their peak - clean it out on a weekly basis...

Hi V
Let me just warn you now, if you think MTS is highly infectious you haven't had MPS (multiple pond syndrome) yet.
You are just one step away from a fully fledged koi pond.


Well this answers the question? Guppies don't survive the highvel winter in outside ponds
Let this be a lesson to all, No more guppies need to die in vein again. Once the average temperature drops below 15'c, It's time to bring them indoors. Don't wait for that winter cold front.



had green water for a yr, left the filter to do Its thing and had clear water ever since
I have had the same experience, saved me from putting in a UV light. With the bio filter running and some water lilies, good bye green water.


rather leave the pump on from now - you will hae a biologically alive filter,ready for the new season...
If you don't, come spring and a little warmer temperatures, your fish are in for some nasty diseases if they don't poison themselves first

Good luck
Post pictures of your new pond when this one becomes too small :)

Thanks for your comments...

@ azurekoi (http://www.tropicalaquarium.co.za/member.php?1190-azurekoi) and @ Khalid (http://www.tropicalaquarium.co.za/member.php?350-Khalid) will make sure my pump is on all the time...I understand now, it takes 6 weeks to build bacteria....wow..

Actually guys, the filter seems to be sitting in the water, so the bacteria won't die off totally. But it will definitely not be growing at full capacity.

Uhm...4 hours on and 20 off is not a good way to maintain a filter....24/7 - 365 leaves me feeling a lot better abot the health of my fishies...lol

I fully agree, but at least it's not a complete wipeout on a daily basis :)
What will be the effect of running the UV 24/7 though? Won't that kill all the waterborne bacteria and have a negative impact on the filtration?

@ Whipme (http://www.tropicalaquarium.co.za/member.php?377-Whipme) Yes, Thats what I need to clarify and get some assistance on?

Must the UV light stay on all the time?

technically yes,for the water. It will not have an effect on the areas where the most of the bacteria is colonised on. i.e. everything else in the pond, the sides, bottom of the pond and on the filter/bio material.


Must the UV light stay on all the time?
The UV light kills microorganisms and algae.Algae also multiply at a phenomenal rate. IMO For a gold fish/guppy pond it does not have to be on all the time, however it would be more effective if left on all the time.
