stargazer Posted May 22, 2007 Report Share Posted May 22, 2007 I could use some advice on changing water in my tank, I have a 30 gal tank. I usually do a 10% change once a week then the other week I do a 20% change is this too much or too little. My ph is 8.4 ammonia 0, nitrite 0, nitrate 10 Quote Link to comment Share on other sites More sharing options...
jayci Posted May 22, 2007 Report Share Posted May 22, 2007 What fish do you have? Ph of 8.2 is too high for my fish/setup. Whats the ph of the tap water? But the amm nitrite and nitrate seem okay. Quote Link to comment Share on other sites More sharing options...
Ianab Posted May 22, 2007 Report Share Posted May 22, 2007 My ph is 8.4 ammonia 0, nitrite 0, nitrate 10 Your Ph is a bit high, but that may be due to your tap water being that way and it depends on what fish you have wether it's a problem. What is the Ph of your tap water? Some species prefer Acid water, Ph below 7. But only play with that if you HAVE to. The other parameters are perfect so I would say your 10% changes have been fine. 10% per week should be OK unless you have a lot of big messy fish. If you get more fish and your nitrates start increasing then you can increase the size and frequency of the water changes to contol that.

stargazer Posted May 22, 2007 Author Report Share Posted May 22, 2007 I don't have city water just well water. fishes are 2 angels, 2 guppies male, 4platys, 2 cory cats, 2 clown loachs, and 6 harlequen rasaboras Quote Link to comment Share on other sites More sharing options...
Caryl Posted May 22, 2007 Report Share Posted May 22, 2007 Clown loaches grow far too big for your tank. They need double what you have. What is the pH of your tap water? Do you have any live plants in the tank? Most recommend 10% a week or 20% a fortnight (which is 2 weeks. I understand 'fortnight' is not a term used in the USA ) Quote Link to comment Share on other sites More sharing options...
smidey Posted May 22, 2007 Report Share Posted May 22, 2007 Clown loaches grow far too big for your tank. They need double what you have. great excuse to upgrade, i got a bigger tank when my clowns grew Quote Link to comment Share on other sites More sharing options...
Wok Posted May 22, 2007 Report Share Posted May 22, 2007 but clown loaches grow really really slow.. so they could be ok in a tank that size. However it does depend on what size they are now Quote Link to comment Share on other sites More sharing options...
stargazer Posted May 22, 2007 Author Report Share Posted May 22, 2007 The tap water varies between 7.4 thru 7.8 on ph as for the tank I am looking to get a 55 gal or bigger this fall . The size of the clown loachs about 1 1/2 in or 3.5 cm(sorry metric is not my speciality), also forgot to mention water has a lot of iron in it , I do filter the water b4 putting it in the tank , using a pur filter on the tap Quote Link to comment Share on other sites More sharing options...
GZ_Loach Posted May 22, 2007 Report Share Posted May 22, 2007 i use water from the ground aswell (bore) which is high in iron, my fish are fine with it. Quote Link to comment Share on other sites More sharing options...
HummingBird Posted May 22, 2007 Report Share Posted May 22, 2007 The clowns will be fine in your tank, they do grow super slow. Quote Link to comment Share on other sites More sharing options...
Ianab Posted May 22, 2007 Report Share Posted May 22, 2007 Are you having any specific problems with the fish? Is there anything in the tank that could be raising the pH? Limestone, some types of sand or shells can leach into the water and cause the pH to rise. Bogwood should have the opposite effect and lower the pH. Also it may be possible to catch rain water from a roof. Sometimes you just need a big plastic barrel under a downpipe. If you are in a rural area chances are your rain water is fairly clean and it should be very soft and slightly acidic. Cheers Ian Quote Link to comment Share on other sites More sharing options...
jim r Posted May 22, 2007 Report Share Posted May 22, 2007 Angels ph7, guppies ph7.3, platty ph7.3, cory ph7 - 7.3, clowns ph7, harlequins ph6.5 , temp range for all above fish 24c -27c. Quote Link to comment Share on other sites More sharing options...
alanmin4304 Posted May 24, 2007 Report Share Posted May 24, 2007 Iron in the water supply is usually caused by the water being acid with dissolved CO2. Generally this is from groundwater being drawn from areas of peat or old swamp country. The iron is in solution in the ferrous state which is soluble. The easiest way to get rid of it is to aerate the water which drives off the CO2 and changes the iron to the ferric state which is virtually insoluble and if left standing will settle out. Iron is not toxic in water it just makes the water taste bloody awful and leaves brown stains on your bath and WC. Chlorinating the water does the same thing--oxidises the iron to ferric.

HummingBird Posted May 25, 2007 Report Share Posted May 25, 2007 Ferrous iron is excellent for plants though, it's much more usable by them than ferric (Flourish excel's main function is to make iron ferrous). Do something to a couple of birds with one stone - try heavily planting your tank. Quote Link to comment Share on other sites More sharing options...
