Yabbie Dabbie Do Posted May 2, 2011 Share Posted May 2, 2011 Hi just wondering if coral sand keeps the Ph up for its life in the tank or should it be replaced every so often? Link to comment Share on other sites More sharing options...
noxious_nasties Posted May 2, 2011 Share Posted May 2, 2011 Never tested it personally but if it/when does expire you should pick up a difference in your pH if it's your only means of buffering. At that point either your fish will adapt to the new value (as cichlids can cope) or you can add a supplement like Kh powder or bicaronate of soda.

fisshy Posted May 3, 2011 Share Posted May 3, 2011 coral sand is a porus product ...another words if you do not look after your water quality and clean the it reguarly it will go off ... like one guy said in your other question .. if to thick lets off gases ... so keep it thin ... about 1 cm in bottom of tank to start with an see if you like it or not .... but thin is better theres less area for all your waste to settle in it so it get to go in your filter instead of your coral sandand when they sift through tha sand they help clean the debree out of it. hope this makes sence ....the cleaner the sand is the longer it last Link to comment Share on other sites More sharing options...

I put it in the other day around 2cm thick and it looks great. For the first time in 18months I actually have alkaline water as well instead of being acidic. Do you think 10% water change every two weeks and cleaning the gravel once a month is enough? Link to comment Share on other sites More sharing options...
tranced Posted May 5, 2011 Share Posted May 5, 2011 10% is pretty small, i wouldnt go less than 30% myself and in summer i go 50% Link to comment Share on other sites More sharing options...
noxious_nasties Posted May 5, 2011 Share Posted May 5, 2011 Gravel is up to you (but if it generally accumulates waste they will add to nitrates). As for the water, if your not keeping sensitive fish don't worry too much about your nitrates. Most probably aim for around 10-15ppm. Alot of fish can take alot higher. You basically do water changes to: A. Keep things stable B. Reduce concentrations of unwanted material C. Dose additional supplements into the water For cichlids its commonly to reduce nitrates and/or add buffers to make the water more alkaline.

Severum Posted May 7, 2011 Share Posted May 7, 2011 I doubt coral sand can go off, when it all dissolves... then it needs replacing Link to comment Share on other sites More sharing options...
