Water Change JBJ 28CF (1 Viewer)

I'm looking to change 5gallon every week on my new nanocube. I have a lot of 5gallon jugs, and was wondering if I go to buy saltwater how long will it last (can I make one run for a month of water changes)? Should I just shake it up?

Also is there a small pump that fits inside of the mouth of the 5 gallon jugs? I continue to make a mess pouring over the top. (I don't have a sump).

you could always pour the water into a clean bucket with a maxijet pump that actually pumps it into the tank via plastic hose (with a clip that holds the hose to the inside of the tank.) The fact that you have more control over the heavy jug at lower height should eliminate splashing since you're not dumping a bunch of water over rocks and such inside the tank. I would actually change at least 10gallons a week on a 28g tank, that's just me personally though especially if you have stony corals in there.

do 20-25% water changes every 2 weeks on my 24gal nano.

Thanks, so I have a lot of live rock. There is only about 20 gallons of water. So was thinking 5 gallons was roughly 25%. Changing 50% seems like a lot, doesn't it? I was going to try to do once a week. Maybe if I miss a week, I would do 10gallons.

Also, I have been buying saltwater from local fish store. Is it ok to leave it in the jug for a week?

thanks for all of the suggestions.

10 gallon water change on a 20 gallon system is actually quite a bit. You'd want to make sure that the temperature, pH, and salinity are a really good match. Also you'll have issues with the temporarily lowered water lone exposing corals (although many corals can survive some exposure to air).

It's fine to leave it in the jug for a week. Just make sure it is sealed. I prefer to keep my water in a shaded area as well.

splashing water on the corals does the trick and as far as temp, pH, and salinity. I would say that properly aerated sw is going to have optimal pH and doing the bucket trick like I posted earlier allows one to put a heater in the bottom of the bucket to heat the water and get it back into the tank as quickly as possible with minimal to no splashing (oh I forgot to mention, you can stick a POWERHEAD in the bucket too.) I would say you guys are freaking out too much about such trivial stuff, if the water is at optimal pH and 1.025 SG, you should be fine. In a nano, you can never really change enough water, but its the keepers tank, so they are entitled to do whatever they wish. That's just my 2 cents.
