ducati Posted September 22, 2008 Report Share Posted September 22, 2008 I am currently renting a house in the country which is on tank (rain) water. Tastes fine etc but I have had several batches of goldfish die in this water. They are fine in spring water but the minute I put them in the tank water they die - the larger fish are OK. What might this be? thanks Quote Link to comment Share on other sites More sharing options...
alanmin4304 Posted September 22, 2008 Report Share Posted September 22, 2008 Goldfish generally carry a lot of parasites (particularly gill and skin flukes) which the parents are able to cope with but fry are very small and are moe susceptable. It may be that. Quote Link to comment Share on other sites More sharing options...
ducati Posted September 22, 2008 Author Report Share Posted September 22, 2008 I agree but I tried putting 4 babies in the tank water that was same temp as spring water and they died within an hour? I also dont seem to be able to hatch brineshrimp in this tank water which is held in a plastic lined wooden tank. Quote Link to comment Share on other sites More sharing options...
Simian Posted September 22, 2008 Report Share Posted September 22, 2008 The problem with collecting water off your roof is that you can get spray drift from your neighbours. Another thing Id check would be the PH, PH shock kills fast Quote Link to comment Share on other sites More sharing options...
Caryl Posted September 22, 2008 Report Share Posted September 22, 2008 You may also have spray residue or something else on the roof (tank)contaminating the rain water. Quote Link to comment Share on other sites More sharing options...
Caper Posted September 22, 2008 Report Share Posted September 22, 2008 So is there any way he can test the water? With the usual test kits? Caper Quote Link to comment Share on other sites More sharing options...
Caryl Posted September 22, 2008 Report Share Posted September 22, 2008 Not using aquarium test kits no but there must be places that can test for contaminants etc. Quote Link to comment Share on other sites More sharing options...
alanmin4304 Posted September 23, 2008 Report Share Posted September 23, 2008 Because there are so many potential contaminants and you are not able to be specific, analysis would not be cheap. Quote Link to comment Share on other sites More sharing options...
new zealand discus man Posted September 23, 2008 Report Share Posted September 23, 2008 Hi PH is your problem...Rain usually is 6.5 PH and goldfish must have at least 7.5... Buffer with lime stone and backing soda to get PH up..I use rain in all 122 tanks and just have lime chips and cockle shell with africans are just fine. Can also increase hardness with spar pool stuff...My Tanks still get daily input of rain and PH stays up.. By the way..I was the former owner of Burbank Goldfish Farm and bore water was so hard even malawi's would not have liked it...Phill Quote Link to comment Share on other sites More sharing options...
John Rimbauer Posted September 23, 2008 Report Share Posted September 23, 2008 I've seen a pond in the Franklin area that had fish dying in their pond - the ultimate cause was the concrete water tank. The water going in was pH 6.5-7, coming out it was about 8.5+ - the test papers maxed out. It might be worth checking out where the water is stored as well.

livingart Posted September 25, 2008 Report Share Posted September 25, 2008 So is there any way he can test the water? With the usual test kits? Caper yes put some fish in and see if they die seriously, residues off the roof or ph Quote Link to comment Share on other sites More sharing options...
new zealand discus man Posted September 25, 2008 Report Share Posted September 25, 2008 Oh OK - phill what's the best way to adjust pH for say 200L? After the rain we have had this year i cant see roof being an issue..But for 200.L from 6 PH to 7.6PH is just about a rounded teaspoon of backing soda..5 Gms...To keep it there the the shell or lime stone is the long term key Simple tester will tell you if acid or moved up.. Stevenson's depot at Drury have shell and lime stone at $10 a bag of 20 L each..If need just for one tank come see my and ill give ya some...Phill Quote Link to comment Share on other sites More sharing options...
