Hey all. Im changing salts. Been using red sea coral plus for years. Did a triton test that yielded some elevated metal results. I blame the salt. So whic should i go with?
I'm a fan of Instant Ocean or Reef Crystals so I could probably give you reassons to switch, but I still have to question putting so much onto one odd test result.
No. I wish i had a control. Ive had problems sustaining stable alk and many of my colonies have rtn or stn over last few months. Thought id change something since everything else stays constant
RSCp isn't exactly unpopular. Unless you've seen others using that salt experience the same issue, I'd be looking elsewhere for your problem.
RTN-type symptoms always begin with stressed corals, and that stress is usually from an unstable tank (in one or multiple ways). From several accounts, it's likely that most of us with older tanks have some elevated metal levels (myself included) but RTN is very uncommon. (Never seen it in one of my tanks.)
I've always used RC, but I like the argument presented for using IO. There is always a big swing in alk after a WC, and maybe a salt that was less alk loaded would be a better bet for stability (those of us that are dosing are relying on the continual dose to maintain stability anyway). Good thoughts!
This "big swing" that keeps being mentioned is because of going too long between water changes or inadequate dosing in between changes...not the formulation of the salt. Switch salts and you'll have the same "big swing", just at a lower point on the alk chart...and possibly dipping into pH-swinging range.
I've been thinking of changing from reef crystals also. My alk in my 125 w/40 sump is at 10. I like big water changes. Also I think there are huge changes from batch to batch. I have a few tanks and I mix 30-50 gallons a week in a brute. I use a 1400gph cheap pump, a 750gph pump with hose for water changes and a jebao wp40 to mix salt. I see the residue. It gets so bad I use a filter sock inside to filter the flaky particles.
This is not the salt's problem or you'd see thousands of posts with people complaining about the same thing. Could be any of a few things causing this for you, but issues with storing and handling your salt would be my first guess. Sounds like moisture is getting into your salt before you mix it.
I'm not worried about the alkalinity of reef crystals since I only do a 10 percent water change. I'm more interested in knowing what is the brown residue ring left in my mixing bucket.
Supposed to be clay used in the mix. Tropic Marin mixes out with a black residue, fwiw. Since everyone gets it, it's clearly not an issue, either way. No worries!
