Barnacle Posted March 16, 2013 Report Share Posted March 16, 2013 Well im guilty of it. Having my fish some 70-80 km from me, and dads house not having had rain for months now... I've not done a waterchange for about 3-4 months. Only topped up the water once in that time In saying that, i have only had 2 threadfin rainbows dissapear in that time... I say only as i tested the water today: PH 6 Kh 0 Gh 8 Nitrates 80-160 (pretty much off the scale) Changed 50% and the parameters afterwards are as follows. (Note our water tanks have been filled by a truck... probably sourcing it from a bore) PH 8.4 Kh 5 Gh 4 Nitrates 40-80 The moss has really taken hold in the tank, and id imagine i wouldn't have many fish left if there wasn't plenty of plant mass (ie moss) No algae has been growing on the glass either in that time, haven't cleaned it once.

livingart Posted March 16, 2013 Report Share Posted March 16, 2013 there are times when not disturbing your tank can be good :thup: Quote Link to comment Share on other sites More sharing options...
Ira Posted March 16, 2013 Report Share Posted March 16, 2013 Put a lot of plants in, good lighting and relatively low fishload and there isn't a huge amount of maintenance needed beyond feeding. Looks like it could use some pruning though... Quote Link to comment Share on other sites More sharing options...
Caryl Posted March 16, 2013 Report Share Posted March 16, 2013 I do not do water changes over the summer months as it causes a lot of problems. I suspect it has to do with the low water table, from our artesian source, concentrating the nutrients. My tank has not had a water change yet this year but it was topped up in early Feb. I have a lot of plants and a low fish load. Filter gets cleaned every 18 months - 2 years. Quote Link to comment Share on other sites More sharing options...
alanmin4304 Posted March 16, 2013 Report Share Posted March 16, 2013 What usually happens is that the nitrate from excess farm fertilizers (applied at a greater rated than the grass can utilize) concentrates between the root zone and the water table, then goes in to the water table when it rises.
