    ^ click that one with the + sign on far right bottom(as Fondles says)...do a few of them....and then hit the 'reply to thread' button on the bottom left.

    That then opens up to a new page with all your quotes on

    And this???

    I have to give the green to Barty... his method works! Sorry Fondles and Dill... couldn't get the bottom right one to happen, also Dill you were on the next page and can't get you included in the multiquote using either method.

    Thanks guys!

    Solution to the next page problem:

    Mark everything you have in the quote box with the mouse and copy it.
    Switch to next page, paste into the empty quote box and then continue quoting as you did on previous page.

    ^ Many thanks... this is getting more complicated than trying to safe my fish!

    Only two further fatalities this morning... by the way.

    I think that is a choice your browser is giving you depending on how you have configured its link handling, it's not a TD quote option. I can at least not find it.

    I'm gonna persist with my pH measurements... even though I appreciate that the 'multi-quote' issue is a lot more interesting!

    A packet of pH Test strips turned up in the post today.



    The strip on the left is how they turn up, the strip on the right is after testing in our pond.

    Bang on pH 7 I would say, so neutral, and well within the quoted fish comfort zone for pond water.

    Not sure what this means to be honest...

    ^Do not give up. There is surely an authority over the people's Mickey Mouse fish pools. Why not to ask the Ministry of Fish Welfare (MoFW)?

    Doesn't seem right, when you take your sample that you are going to test, you wont to take it from about 18" down, not from the top.

    I did another test from a different part of the pond today, and made sure I held the pH test strip an arm's length under water...



    Again... looks to be bang on pH 7, or neutral. This does seem strange.

    My digital pH meter with a TDS meter turned up in the post today, but I need some distilled water to calibrate the pH meter so that will have to wait until tomorrow. The dissolved oxygen testing strips also turned up.

    Today was the first day since last weekend that we lost no fish, but maybe there's hardly any left...

    Start a Poll on the options Mendip and TDCSI will see you right.

    Very unlikely.
    Simple observations.

    Multi guess with a strong hint cuts through even TD Saturday PM fug, come on Mendip display the options, including chucking a live electrical appliance in.

    I take it by the recent posting rate the pond is back to normal.

    ^^ Unfortunately not... just seemed to have been busy this week.

    ^ Most maybe... but not all!

    I was watching the pond today (around midday) and there are a lot of fish coming up to the surface to gulp air.

    Few appeared to be tilapia... I think we've lost all the big pla nin and pla tabtim.

    Most fish appeared to be catfish coming up for a gulp of air and then disappearing back down again.



    This one looked to be one of the few remaining decent sized pla nin.



    I threw in a handful of pellets to see what's what (we've stopped feeding for the time being as un-eaten food further depletes the oxygen content of the water)

    A lot of catfish appeared.





    It's not clear from the photos, but I reckon the vast majority of fish left in the pond now are the catfish pla duuk, and also the striped catfish pla sawai. I've caught pla sawai in the pond before and they have vicious spikes coming out of their pectoral fins and are very hard to handle.

    This is all a bit of a shame for a fish an' chip loving falang... the Thai contingent will be well happy eating catfish curries and stir fries. I may have to experiment with filleted catfish fish an' chips, but can't say that I'm too optimistic of the outcome, even with my new phone!

    I decided to give the water a good testing. This project is already getting a bit out of hand... partly due to having spare time on my hands and the ease of buying pretty much anything online on Lazada. Here's all the stuff I've ended up with...



    Anyway, first the pH...

    I would say the paper strip indicates somewhere between 7 and 8. The fancy new digital meter says 8.3. I wafted about the paper strip around 18 inches under the surface, but the meter can only be used just under the surface. If you go deeper than that it will bugger the electrics. Either way, the water seems to be nicely within the safe pH range of 6.5 to 9.0.



    Next up... TDS (which I have recently discovered is Total Dissolved Solids)

    The pond temperature was at 29 deg C.

    The TDS was at 276 ppm. And, as with the pH meter, the TDS meter can only be used at the surface. I would expect TDS to increase with depth.



    The internet says optimal TDS for a fish pond is below 200ppm, so here may be a problem. Does an algal bloom increase dissolved solids? I think I may need to pump out more sludge from the bottom of the pond next week and top up with fresh water.

    Next up... Dissolved Oxygen.

    The testing kit came with five bottles of chemicals and powders and detailed instructions... I would have preferred to have just stuck a Dissolved Oxygen meter into the water, but there ya go.



    After following all these instructions I came up with a figure of between 5 and 8 ppm dissolved oxygen, but I wouldn't really trust that and I reckon each test would give a different result. It was all very subjective.

    I was the only person really showing any interest by this point in the proceedings...



    Mind you, tell Yogi there's fish for tea and he'd soon change his tune!

    The internet says a safe dissolved oxygen range for a pool is between 5 and 12 ppm... so I'm at the lower end of that but just OK. Seems I'll have to keep the pump and waterfall running for the foreseeable future to maintain that oxygen level.

    Feel for you, its a bloody guessing game to find out what has happened. Are you going to try to restock?

    So filter and oxygenation ?

    Do you have one of those cheap, plastic hand pumps? You could easily take a water sample 18 inches down using one of those.

    Live with what you have, Mendy.
    Perhaps the situation will adjust and amend itself naturally, as it seems to be already.
    Don't overthink the locality.

    Nothing wrong with a supply of local bottom fish.

    Your water looks really dark green to me. With your oxygen levels that low your just another algae bloom away from another major die off. I bet the deeper you go the less oxygen in the water. You need several fountains in your pond on permanent basis to properly oxygenate the water. If you want to have other fish that you like to eat in the pond, your going to have to control your algae levels.

    Pond Algae Control. Algae control in ponds is a very important part of maintaining a healthy pond. In very high densities, algae blooms
    may discolor the water and out-compete, poison, or asphyxiate other life forms
    . Some algae are toxic to humans and dogs.

    Pond Algae Solutions. Pond algae is the bane of many who enjoy keeping ponds. They basically act like plants and need both sunlight and nutrients like ammonia. and nitrate to thrive. These nutrients come from the breakdown of organic matter such as leaves and grass, fish waste and uneaten fish food.
    Yes. you need to remove more sludge and a water change.

    Sorry for the text ran into some weird problems when trying to copy/paste.
