duganderson Posted September 23, 2016 Share Posted September 23, 2016 I'm looking at doing a 80-100% water change on a 34 g. cube that has been poorly maintained for about a year. There are a couple nepthea, a few gorgonians, 1 toadstool leather and three rose bubble tips anemones in there. Are any of these things super sensitive to a HUGE water change if I try to match the temp and salinity really well? Link to comment
NYfishies Posted September 23, 2016 Share Posted September 23, 2016 How much sand/rock is in there? That is where the bacteria hides. Should be fine. Link to comment
duganderson Posted September 23, 2016 Author Share Posted September 23, 2016 about 20-25 lb of rock and no sand Link to comment
markalot Posted September 23, 2016 Share Posted September 23, 2016 As long as you match salinity, KH, and to some extent PH (make sure the current tank PH is not too low from being neglected) there should be no problem IMO. Link to comment
Clown79 Posted September 24, 2016 Share Posted September 24, 2016 The water chsnge shouldn't be an issue but if the tank was neglected for a yr or more, the sand probably needs removal, washing, and replacing or removed and replaced with new sand. Most nutrient issues are caused by neglected sand. Link to comment
seabass Posted September 24, 2016 Share Posted September 24, 2016 about 20-25 lb of rock and no sand Assuming that phosphate is high; the biggest problem that I see is the sudden drop in phosphate. Some of your livestock could be shocked due to this energy source being removed. However, I suspect (again, assuming that phosphate is high) your rocks will continue to leach phosphate for awhile. Before the water change, please post your tanks nutrient levels, as well as calcium and alkalinity. Also a picture would help. What problems are you trying to solve with the water change? Depending on how far out of whack your parameters are, a series of 20% water changes, twice a week, might be an easier transition for your inverts. Link to comment
akdylpickles Posted September 24, 2016 Share Posted September 24, 2016 Start with smaller water changes 20% every other day for a few days and gradually increase to larger. If the tank has been neglected that long you don't want to shock the coral and news by giving them too clean of water. Link to comment
duganderson Posted September 24, 2016 Author Share Posted September 24, 2016 Thanks for the ideas. I did about a 95% water change and the softies and RBTAs seem to be doing fine. Link to comment

Are any of these things super sensitive to a HUGE water change if I try to match the temp and salinity really well? I see no problem. Just match the salinity and temp. Thanks for the ideas.

ricoh Posted September 25, 2016 Share Posted September 25, 2016 i would have said maybe too much too soon and opted for smaller water changes but hey unless we hear it was too much from yourself it proves what ive learnt that what doesnt work for one person works for another in this hobby Link to comment
