kraken Posted June 19, 2013 Share Posted June 19, 2013 Do you guys prefer to conduct wc weekly say 10%, so in a month total of 40% or 20% bi-weekly or 40% once a month? what are the school of thoughts on the % and frequency? What are the pros and cons? Quote Link to comment Share on other sites More sharing options...
Clement_jr Posted June 19, 2013 Share Posted June 19, 2013 i first started doing weekly WC. after observing the corals n water condition which is still healthy at the 2nd week, then i decided to change 40% biweekly.

kraken Posted June 20, 2013 Author Share Posted June 20, 2013 although I would like to try 40% wc each time, however having a 800+L tank, to conduct a 40% wc would meant 300+L of water is needed. I have only 2 x 60L tubs to hold my RO/DI water, at best I can manage is 120L each WC. Quote Link to comment Share on other sites More sharing options...

Bro it also depend on your no3 and po4 if your no3 and po4 under control level and water parameter like ca, mg, kh, trace element all ok no need to change so much. Water change is just a guide not a must follow. Maintian water change is to help those who high in no3 and po4 and also at the same time to top up this trace element if your coral consume alot.

dnsfpl Posted June 20, 2013 Share Posted June 20, 2013 depending on the objective of water change to remove nutrients, higher volume, bi weekly to replace elements, lower volume, weekly Quote Link to comment Share on other sites More sharing options...
kraken Posted June 20, 2013 Author Share Posted June 20, 2013 i do not have problems with NO3 and Po4, probably i should stick to changing 120L per week for elements replenishments... Quote Link to comment Share on other sites More sharing options...
MarcoVan Posted June 20, 2013 Share Posted June 20, 2013 Nano tanks - daily to weekly changes Big tanks - once a month Never scrimp on water changes. End of day I find it cheaper than spending on bottles since the result is direct and more significant than bottles. Quote Happy Reefing, Marc J.

yourdi3 Posted June 20, 2013 Share Posted June 20, 2013 Normally my preference is about 5-10% water change every 2 weeks to 1 month. not hard core corals guys so i guess still not too bad. Quote Link to comment Share on other sites More sharing options...

MarcoVan Posted June 20, 2013 Share Posted June 20, 2013 Sorry bro missed out your tank being 800L. Painass abt a big tank is everything is big. Might want to consider biweekly change to match up to full 120L. Or a drive to iwarna for nsw is possible too. Quote Happy Reefing, Marc J.

Endorrachua Posted June 22, 2013 Share Posted June 22, 2013 My new 200l tank i weekly change 10% until stable will want to do biweekly. Before each water change will do all necessary test kit to decide amt of water to change too. Quote Link to comment Share on other sites More sharing options...
SRC Member solasido Posted June 23, 2013 SRC Member Share Posted June 23, 2013 Mine used to be 2x weekly 40% (20g cube tank). Now weekly 40%. I always try to match the new water parameter with existing one in tank. I noticed that during water change, if the SPS exert slimes it means that the new water parameters differs too much and the coral coated themselves using their slime for self protection. So as long as new water parameters are more or less the same as the current tank parameters, it is okay. For this reason, I stopped using salt with very high Ca, Mg, Hco because it cannot be adjusted down to match tank parameters.
