Re: New pond syndrome! #1
Sorry for the late reply.

The pond sprung a leak and was being constantly topped up with water.

The leak is now fixed and the Nitrite and Nitrate are a little high. I have stopped feeding now for winter and will monitor the water quality as we go.

Should I give the pond another dose of a filter start bacteria or wait 'till spring? I'm thinking that bacteria may die off over winter anyway, but would like your thoughts.

Re: New pond syndrome! #2
Fredrick - The Nitrite levels are not raising as fast now. The last water change was probably over a week ago and today the level was .25mg/l.

There is nothing rotting in there. It's an ornamental pond with no plants. Just water, a pump and air stones.

I have notice though that the Titan 2000 pump collects solids underneath rather then send them all to the filter so I have got in the habit of sticking my pondovac under the pump weekly to get rid of any waste that is hanging around.

Otter - The strips were new. The problem is the scale. They don't read the low levels we wish to test. There needs to be 10mg/l before they start to show any colour change.

That's 10 not 0.1.

Re: Filter and pergolas! #3
The Blagdon Minipond filter should be fine for a pond of that size. the built in UV is adequate, however, the Minipond pump isn't brilliant as it is not a waste handling pump. I would use a Hozelock Titan (actually I do).

Are you sure you have algae problems? Can you describe exactly what you see or even post pictures? A green tint can also be down to excess nutrients in the water. Take out a pint glass of water, if it looks totally clear, it's most likely the excess nutrients causing the green hue. A bacteria boost from Hydra Aqua clears that quickly (from experience). If there are very small particles, it may be down to the newness of the filter (at the time of writing, they have only been out a couple of months) as the foams are less efficient when new. They need to build up a little dirt before they are working at 100% efficiency. Again, Hydra Aqua do an extra fine electrostatic filter layer that you can use to boost the efficiency of the filter.

A pergola will help with the dreaded blanket weed. I have had no blanket weed since fitting mine. It will also keep Herons away. Not sure if it will help defend against a Heron that already knows of the pond's whereabouts though.

I would save the ?300 you have for a filter upgrade as I have found the Minipond to be a brilliant filter.

Re: Winter time plans #4
For a raised pond with brick surround, I find that expanding gap filler foam makes an excellent insulator. Simply drill a couple of holes spray it in and fill the holes of you so wish.

It will also aid the support of the less rigid type ponds too.

Re: New pond syndrome! #5
Sorry didn't post full results, but yes, you are right to assume that Ammonia and Nitrate are both zero. PH is 8.2.

I'm unable to move the fish elsewhere, so will monitor on a daily basis and carry out water changes as necessary.

I'm only feeding a tiny amount every couple of days. Water temp is down to 14C now, so they don't want a great amount anyway.

I double checked the test strips and noticed the scale. At the point they get even the slightest hint of colour there will be 10mg/l and a very light hue of purple 25g/l. Useless. The water would be highly toxic (as mine was) before you had a chance to notice - lesson learned in that respect.

Re: New pond syndrome! #6
I don't get it!

It took three 90% water changes to get the level of Nitrite down to .15mg/l and now three days later it's back up to .5mg/l

What can be causing this?

Re: New pond syndrome! #7
Fred - you say to stop feeding.

My pond is a formal pond with no weed or algae. How long could fish go between feeds under these circumstances?

Re: New pond syndrome! #8
I noticed a couple of the fish were gaping at the surface this morning and knowing that to be a sign of Nitrite poisoning, I done another test.

The test strips were fine. The tablet test was off the scale again.

Went to LFS and bought a brand new Blagdon test kit and the Nitrite is indeed off the scale.

Doing a 90% water change now. I normally use Interpet Fresh Start, but incase it isn't working properly and is allowing the chlorine to kill the bacteria I have bought a different brand.

What is the best filter primer? I've been using an Interpet one, maybe that's no good.

So many variables here!

Re: New pond syndrome! #9
I've been using Interpet Nitrite test.

Tablet into a test tube and shake. One set were a year or so old so could be out-of-date. I got some new ones and they also gave a high reading.

I'm not sure what to trust.

Re: New pond syndrome! #10
Got some quick test strips and both Nitrate and Nitrate are shown as trace.

Hmmm.
