Hi,

Pretty new to all this so i've been looking at quite a lot of books and sites before and after making my pond, and they all seem to give different answers to the questions i've been asking. For example, some say you need 20 bunches of oxygenators, others say just 2 or 3 with a couple of plants. Some say you need this much water for this much fish...other's give half of that...or you need a filter...etc etc.

Anyway, to cut things short, i've just decided to ask if you think that this pond would survive =P.

It's not too big, 1.5m by 1m and an average depth of ~40cm (50cm at deepest with 25cm marginal shelf).
In it, there a 4 marginals, 3 oxygenators and one waterlily. There's also 4 comet goldfish (around 8cm) and a small fountain pump that's just pumping water upwards.

I live in melbourne, australia. I guess you would call it temperate. The summers average in the low to mid 30's with the occasional low 40 (in °C). The winter is pretty mild, you get frost and i've known pools to ice over, but by late morning it would've all melted. Lowest i can remember is 2°C, never below zero. Pond gets about 5 to 7 hrs sun depending on the part of the pond. Unfortunately the lily is the 5 hr side due to an unforseen problem in digging (the builder's dumping pit is not fun to dig through T_T).

I'll be really glad for any help you guys can give me. Thanks!

Sounds like 3'x5' and a bit over a foot deep and sounds workable to
me. There are always lots of ideas as to how something should be
done, especially concerning ponds. Smaller ponds can be considered
more difficult to maintain, so you may have to monitor it regularly to
keep things working smoothly. Most of us have gone to UV clarifiers
and filters so we can have clear water and see the fish better, If you
can see your fish and are happy, you are fortunate and don't need to
make changes.

Hal is on target. Your pond is small enough that a hot summer can
heat it up a great deal. That would not be great for the fish. Loads
of us have ended up increasing pond size.

Keep us posted!

Small bodies of water can be very volatile, temperature wise. In a hot climate with temps over the mid 90's plants and fish are going to struggle through the midday heat.

Shade through midday will make a lot of difference... Perhaps some tallish pondside plants, tallish marginal plant in the pond and a heat tolerant waterlily will keep the water in the eighties, rather than the high 90's

Ditto from me. The ideal solution if you can't increase the foot print, is
to simply make it deeper.

Ah k. Hmm, seems like i'll have to have a think about this...seeing that making the pond was hard work haha but if it's necessary. Though, 50 cm is 1.6 ft (1'7''?? dunno how things work over there haha). Would that make a difference? Or is deeper/more area still better?

Where ponds are concerned, I would say bigger is always better (until you
need a boat to deadhead lilies!) Large ponds are much less prone to large
swings in temperature, and balances like ammonia and ph. That's not to say
you shouldn't build a small pond, just that a large pond requires less
monitoring. I only check my water parameters monthly, and even less so in
winter. If you plan on koi, you absolutely need a larger pond with IMHO at
least 3 ft of depth and a minimum of 1000 gal.

Deeper is better in places that get hot (or cold, though a heater can
negate that). A patio umbrella may be necessary on those really hot days.

As far as filter, that is all dependent on # of fish. Personally I'd take
the comets back and get fantails. They produce fewer offspring.... and
they're really easy to catch if there becomes too many. ~ jan

In Arizona, when it gets too hot(over 115F), people have been known to
put 300lb blocks of ice in their pool for comfortable swimming. Do Koi
like ice?

I plan a 12' dia deck island over my pond for both shade and heron
protection.

Probably better in a koi pond would be frozen water filled milk jugs, so
you don't have to worry about chlorine. ~ jan

To quote Ratty from /The Wind in the Willows/, "There is nothing --
absolutely nothing -- half so much worth doing as simply messing about in
boats".

I don't see the problem :-)
