I had one Jess, but it took forever to get to the level of water I needed so I decided to just start buying 5 gallon cdn spring jugs. Glass gets dirty ever 4 days or so.

They deliver once a month, but for my weekly top offs I pick up from this place in steveston or a crappy tire. I eventually plan to switch over to the steveston shop for my monthly water changes also.

I already calibrate with solution, so I believe it is pretty accurate. as for the clean up crew, I will grab more along with a new test kit this week. Thanks for your feedback.

I used to use the spring water until I started to measure the tds in it and would sometimes get 15-25 tds so I switched to r.o and never looked back. cleared up a lot of algae issues and corals are happier

Just a thought stray voltage

Personally I'd stop dosing foz down or any other chemical that you're using that isn't just the basic alk, cal and mg. I find if I use any "reef safe" treatment for anything I'm gonna loose a coral or two.

Are your Scoly's under direct light? maybe shade them a bit.

I'd suggest a big water change or two but I know thats hard with your volume of water especially if you aren't making RODI at home. Still when things go buggy I like a couple of big water changes to remove anything that may be in your water.


Are all your other coral totally fine? What else do you have? Do you have a lot of coral and its just a couple that are going bad but everything else is fine?

I just did a 90g water change last month due to a cyano outbreak. I have scheduled a WC this week as the cyano is back and I am about to put in chemiclean.

As for my other corals, zoas, doughnuts, and acans are fine, as are some of my scolies.

as for adding stuff, I am going to stop dosing zeobak and fozdown going forward, and try this carbon dosing that some others have suggested. although I still plan on using prodibio bio digest every 2 weeks.

thanks again everyone for your feedback. really appreciate your advice and tips.

Just remember that stopping 2 things, starting up a major thing and also adding chemiclean is a lot on your system. Coral hate that...lol

Chemi clean tells you to turn off your skimmer for 2 days, don't do it! just take the collection cup off and let the skimmer just overflow back into the tank. Cutting off the skimmer really reduces the oxygen in your water. This will make your fish and coral very unhappy......trust me......been there....

If your nitrates are already reading 0 why start carbon dosing? When I started using NOPOX as a carbon source my tank went a little wonky and I lost a couple of big sps colonies.

Oh and carbon dosing usually ends up in a cyano bloom when you first start out, a lot of people report this. I had it happen.

I really like bio pellets. They start off slow and sort of gradually ramp up giving your system time to adjust then you just forget about it and re fill the reactor when needed. Pretty stable way of carbon dosing IMO. My nitrates were at 80 when I started and now they are down to 5 but it took 3 months. Nice and slow.

Just some stuff to think about. I can't tell you how many tank crash stories I've heard from reefers trying to quickly fix an issue with dosing or adding chemicals.

Lastly, if you're worried about your scoly's, feel free to give them to me. I'll take them!!! lol ;)

im not sure tbh, ive been trying to research this topic all morning at work. it seems to me that nopox will reduce my nitrates, but I need the opposite it seems, and need to introduce nitrates into my system
