Water changes

[reef-nut]

How much do you do and how often? What kind of water, tap, RO, ect.? How long do you have it mixed up ahead of time?

 

[J. Montgomery]

10% water change once a week.

Instant Ocean salt [supplemented with Prestone Driveway Heat (calcium chloride), MAGflake (magnesium chloride), and Epsom salt (magnesium sulfate)] dissolved in RO/DI water and mixed with a powerhead overnight. Sometimes I only mix it for a few hours.

every other week I do 10% water changes two days apart with RODI water mixed for two days with air slurping powerhead. I have 300g in the system so this is what size batches work for me, and everything always looks happier after the 2nd change probably because I blast my rocks on the first change and change my filter socks just before the second one.

 

[I-K@ndY]

180G - I do 20 gallons a week with RO water.

 

[saltwaternewb]

10g tank, 2g water change every week using distilled water and SeaChem Reef salt. I only mix mine a few hours prior to the WC.

I "try" to do a 10%-15% water change once a month.. but if I suspect any issues with the tank, I remedy with more frequent water change, probably increase the frequency by 2-3/month..

I haven't done a water change in 2 1/2 - 3 months.. yikes! but everything looks better.. :hammer:

I am the worlds worst at water changes, but I just did one dau before yesterday! Anyway I am going to shoot for 10-15% every 2 weeks from now on.

I have a 29 gallon tank and I try to change 15% every week so it's about 4 gallons. I use Instant Ocean with the addition of Magnesium powder. Bring it up to temp and salinity and let it mix anywhere from 2 hours to a day.

Everything looks nice and happy after waterchanges.

10% once a week using RO and Instant Ocean salt for my LPS and SPS tanks. 10% once a week using tap water and Instant Ocean for nutrient loving soft corals.

 

[coral88]

20% once a month on my 20Gal tanks
20% once every three months on SPS and soft coral grow out tanks. 100gal tanks one fish each

 

[robinreefer]

10% each week with RO water in both 55g tanks-both mixed with LPS,SPS,and softies....all is well

 

[reef-nut]

10% once a week using RO and Instant Ocean salt for my LPS and SPS tanks. 10% once a week using tap water and Instant Ocean for nutrient loving soft corals.

This is what I do, a 10 to 15% change once a week using instant ocean, because I have mainly softies. I am still having some pouting, but nothing dieing. I can not figure it out it is starting to really upset me. I have done water changes. I tested for everything but alk. and cal., because I do not have them test kits. everything test fine. I love this hobby so much I have been praying for the corals. GOD made them so I figured he would want them to stay beautiful.
salinity 1.025
ph 8.2

[Russellaqua]

How big is your tank? I'm just trying to get a feel for the amount of light you have going in.

 

[reef-nut]

90 gallon

 

[rocko918]

Could be the lighting. Thats not a lot of light for a 90. How tall is the tank? Are the corals near the top doing better than the ones on the bottom?

 

[rdvab]

240 gal tank 30 to 40 gal every 4 or 5 months........

 

[Eklikewhoa]

30g tank 5g changed weekly with Oceanic salts.

 

[Azurel]

60g cube I will do my first water change on this one this weekend and will probably due a 10-15 gallon water change, I use Red Sea Pro usually mixed a day before but sometimes only a few hours before using.....
