How young can comets reproduce?

Not unless there was lots and lots of crushed coral and then would only effect GH primarily.

i didnt read all the other posts here, but... i will say thatt i got rid of all my goldy varieties a couple years ago. but any that were born and i kept were active in spawning the next year... it seemed this was the case for all over 2" or so. they also spawned numerous times thru the season....

Maybe about 100 lbs? Total water volume is about 9000 gallons.

I couldnt find my own thread a little while ago, so made a new one with some pics. Netted her to get a better look. Dont think this is "right".... you can see the pics here... https://www.gardenpondforum.com/topic/10469-fat-pregnant-deformed-sick/page__fromsearch__1

Hard to say. Can't remember reading about a case of someone using crushed coral in a large pond and providing any good data. But there is a ton of very good data on crushed coral in aquariums. If that data is scaled up to 9000 gal we'd be talking about, I don't know, maybe 500-1000 lbs. Their data shows it has little effect on KH and is too slow to support GH, just too slow to dissolve. But they do way more water changes than most ponds. So maybe in a pond 100 lbs would be enough for reasonable GH. But not KH.

Bottom line, if you're concerned about your bloated fish, I would double check the KH test kit. Easy enough to eliminate that as a cause.

Worse case, if the test was off, what would the harm be? What signs should I be watching for? Other than this one fish, everyone else looks fine. I couldnt find this tread earlier (sick and dumb LOL), so I posted pics of it to another thread. Link above in my prior post...

I cant remember now, it has been years, but when we had the marine/reef tank (180 gallons), I want to say it took something like half inch of crush coral to maintain a PH of 8 - 8.2??? Wish I could remember... Been years.. Lost all the inverts thanks to Hurricane Bob... The PH would lower with water changes, and again, my memory is vague at best, but I want to say when the PH dropped to a certain point, the coral would dissolve, and raise the PH again... would that not be the same principle in a pond? KH/GH, it seems that no matter how many ways it is explained to me, I just cant absorb it further than somehow one is a buffer and helps stablize the PH...

We use crushed oyster shells to keep the gh and kh decent (this last summer 100 lbs), which helps keep our ph decent. I am pulling pond water for the fish tank as long as I can (until it freezes, if it does this year) Our straight well water is too acidic and soft. I was even looking into alkalinity up (used in swimming pools and tubs ) to help bring it up if I have to use well water for the inside tank, checking into it being fish safe or not.

Different fish react differently to different conditions.

Almost everything I know on this subject is from aquarists. They've done lots of research in this area and publish lots of data. Pond keepers provide almost no info on the subject. Here's one source

Aragonite or crushed coral is sometimes employed for KH and GH stabilization, however aragonite and crushed coral (as with Wonder Shells) only aid to stabilize KH (they are poor buffers, especially crushed coral) and should not be used in place of a true KH buffer such as Sea Chem Alkaline Buffer when true buffering is necessary due to fluctuating KH or pH whatever the cause may be.

It makes sense to me. There's lots of details that can be double checked and they checked out imo. But everyone should do their own checking.
