JK Posted July 20, 2009 Report Share Posted July 20, 2009 Hi all Lately I have been noticing that my tank keeps reverting to pH of about 6.0, possibly even slightly lower. Fish don't seem to mind too much but just wondering if it's something I should be worried about and if there is anything I should be doing. I am pretty sure that it is due to the large piece of wood that I have in the tank. I do 20% water changes weekly but it doesnt seem to make much of a difference. I also have some pH up but dont want to add stuff to the tank thats not essential if ya get what I mean. Thoughts?? Quote Link to comment Share on other sites More sharing options...
jim r Posted July 20, 2009 Report Share Posted July 20, 2009 I had a similar problem with 1 of my 950L tanks. I was doing 50% weekly water changes but the PH always dropped to 4.3 in 7 days. I thought it was the drift wood also untill I removed the inhabitants (2 Oscars 8 Bala and an Arrowana) the problem disappeared,I put it down to big poopers.

Foxjxa Posted July 20, 2009 Report Share Posted July 20, 2009 What's your ammonia like? I would think it's something to do with the amount of waste being produced vs your filtration/bacteria. Quote Link to comment Share on other sites More sharing options...
Caryl Posted July 20, 2009 Report Share Posted July 20, 2009 What size is the tank and what fish are in it? Quote Link to comment Share on other sites More sharing options...
JK Posted July 20, 2009 Author Report Share Posted July 20, 2009 Cheers for the responses so far. Ammonia is coming up at very close to nil, maybe 0.1 at most. Did remove a fair few poos from the tank this weekend though. Have a GBA about 5inches long who knows how to do them :lol: Carryl - tank is 120ltr so not huge Has the following fish 2 x small blue rams 2 x GBA (1 of which is 5inches) 6 x neons 6 x rummy nose 4 x glowlight danio 2 x dwarf chain loaches Quote Link to comment Share on other sites More sharing options...
Caryl Posted July 20, 2009 Report Share Posted July 20, 2009 I assume the tap water pH is higher? Have you tried sitting a tap water sample overnight then testing the pH again? My thought too was you had big fish in there and it was their wastes causing the drop but they aren't big fish. Quote Link to comment Share on other sites More sharing options...
JK Posted July 20, 2009 Author Report Share Posted July 20, 2009 Yep tap water about 7.0 - 7.2. Tested it as I was doubting my test kit for a wee while. Will stand some tap water overnight and test it tomorrow Quote Link to comment Share on other sites More sharing options...
phoenix44 Posted July 20, 2009 Report Share Posted July 20, 2009 you probably have really soft water. try raising the KH Quote Link to comment Share on other sites More sharing options...
JK Posted July 21, 2009 Author Report Share Posted July 21, 2009 How do I go about that Phoenix. Have never really bothered with water hardness / softness before. Are they any recommended articles that I should read on this subject? Quote Link to comment Share on other sites More sharing options...
LYNDYLOO Posted July 21, 2009 Report Share Posted July 21, 2009 Maybe try reading through some of these Threads you might find something of interest in them search.php?keywords=raising+KH&terms=all&author=&sc=1&sf=all&sk=t&sd=d&sr=posts&st=0&ch=300&t=0&submit=Search Quote Link to comment Share on other sites More sharing options...

LYNDYLOO Posted July 21, 2009 Report Share Posted July 21, 2009 No Worries The Search Option is always a good place to start Quote Link to comment Share on other sites More sharing options...
JK Posted July 21, 2009 Author Report Share Posted July 21, 2009 Yep I know. Had done a few searches on this site (with more meaningful results than 'raising kh') and also elsewhere. Was just keen to hear if anyone had any recommended articles on the subject. Quote Link to comment Share on other sites More sharing options...
