Without being able to test, how do you know what's high? Could just be nitrates, could be both, but I wouldn't use lanthanum chloride without a clear target number. Gfo? Maybe.
So I did test it and stated I have 0 phosphates. There is nothing on the label of the product I stats what to dose if 0. Nitrates I normally have to dose cause there's not enough via testing. Brightwell didn't return my phone call so figured ide ask the community here.
And I doubt many (any?) in the community would advocate adding something as strong as lanthanum to a tank without first knowing what the actual numbers are (which you can't know until you remove the algae...)
Perfect! Then this is advice that I'm looking for then. And as you said earlier a better cuc should hopefully help my situation then. May I ask you opinion on phosphat-e?
It's lanthanum chloride. I personally have never used it but some do. It can lower phosphates really quickly if not used carefully, which can cause other issues. There is anecdotal evidence that if not properly filtered out, the precipitant that forms can injure fish, tangs in particular.
They will be overwhelmed for sure imo but I will have to keep plucking. This is even after I pulled and scrubbed
Unfortunately, that's not the one you want.
I get your point regarding the phosphorus checker, but if we have a target range of 0.01-0.03 ppm phosphate (I personally shoot higher, but to each their own), wouldn’t anything under 0.01 still be too low, regardless if it’s an absolute zero or the phosphorus checker reads a few ppb? I mean .01 ppm phosphate translates to just under 4 ppb phosphorus. To me it’s overkill to go with the phosphorus tester. Doesn’t matter if you pick up anything from 1-3 ppb, it’s still too low
What the right phosphate concentration should be is debatable. If you are shooting for 0.01-0.03 ppm, the LR model can't read that and will show zero, but the ULR can.
