View Full Version : Urgent advise needed.

Had a massive Ca overdose tonight. The DOS switch on apex got set to the on position and dumped almost a 1/2 gallon or BRS ca additive in about 5 hours. I am doing a 30 gallon wc as soon as I can get the water temp down under 80 degrees. Rodi I sits the garage and is 93 dang degrees.

Help please. Sps dominate reef 2 x large rbta's which closed up some, promoting me to look closer and opened the cab doors to see the ca 1/2 empty.

Help please. 80 gallons total water. 30 gallons being prepped now. No rodi left so I really don't want to use tap water if it will take more that a 30% change.

Can you go to petco and get the ready made saltwater in a box?

I, dumping in 30 gal of fresh SW now. Think 30 new of 80 total gallons be ok?

I'd make some saltwater as you normally do and move the corals into that while you get your tank back in order. That's assuming your corals can be moved somewhat easily, but better that them the whole tank dying

I brought it to 78 degrees with ice for the ice maker.

35 gallons changed. Overdosed almost 1/2 gallon. Nems are super stressed. 40 more gallons will be ready to mix in the AM but this will have to do tonight. Way to many corals on rocks to move them. I'm sure this has affected kh dramatically but I'm letting the tank turn a few times before I test it. Can't believe this sheeat!

Did you test for Ca and Alk levels? Doing W/C is the best thing to do.

Tank has turned a few times and tested.

Ca 475
415 Last test (this morning crazy enough!)
406 average

Kh 8.85
8.9 last test this morn
8.5 average

Ph 8.19
Avg 8.08

45% wc as soon as I noticed the issue hopefully will minimize the consequences of such a stupid error on my part. Need to check mg yet as this bucket has been mixing a crazy 1050. Mg doesn't concern me right now. I'm really shocked I didn't see a higher ca ppm and dip in kh.

Always have some new salt water ready and on hand kiddos! And stop dicking with fusion all the time!!

I think you would be fine just leaving it be now and letting it drop naturally.

07/22/2015, 11:31 PM
Yup, I jumped the gun sorry.

1200ml was dosed between 7:00ish and 9:30pm in 200ml increments 30 min a part. Dodged a bullet I think. All looks fine. Fingers crossed and praying to the good lord above.

When I was running a doser I also had it hooked up to a little light so when the doser was on the light was on as well. That way I would notice it and hopefully jar my memory that something is wrong.

I think you'll be fine; nems are super-sensitive unlike corals and will be upset at the slightest change.

This is slightly off topic, but I'm a bit surprised that your DOS continued running like that when the switch was set to on. I just started using a DOS for auto water change and the other day I pulled out a couple of quarts of water to take some frags to a LFS. I was going to manually transfer some water from my NSW reservoir to replace it, but I saw the DOS and figured I could just run it for a while to replace the water. So I turned on the DOS NSW pump and it ran for two or three minutes, then stopped. I figured it must have been some sort of safeguard put in place to prevent overdosing if the switch was left on, but I suppose it could have just been resting and would start up again in a few minutes. I didn't really give it much time before I put it back to auto and manually transferred the water.

If it doesn't have a safeguard in place like this, perhaps it should
