Coral Issues/Water Parameter Problems?

[mcarroll]

I have a Nuvo Fusion 30 Pro Long!
I use salifert tester kits and a hanna checker for nitrates

yeah i didnt realize it got that high and then ive been controlling it with adding rodi water every day for topoff so it doesnt spike up again.
I do have 3 fish and inverts, i feed a big cube every day..im wondering if i should even increase feeding even more? I also feed reef roids to the corals every oth4er day or so as well.

Ive been checking them with saliftert nitrate checker and also the hanna checker and yeah they continue to show super low...at this point all ive been doing for the last 2ish weeks is simply topping off..trying to get some nutrient numbers up..will be posting updated parameter tests in a few minutes.

Coral food like this is mostly wasted/not eaten, so I would not recommend that.

Feeding your fish more makes sense if you aren't feeding them much. But still don't waste food...feed as much in one go as they eat and not excess. (Do that each time you feed....can be X times per day.)

What are you testing phosphate with? That's one of the hardest tests to read, so if you're doing drip-test, you may want to take extra measures to get an accurate reading by having a second vial of untreated tank water as a color comparison next to it. Our eyes are better at comparisons.

here are updated numbers and parameter checks

nitrate checks were done with salifert tester showing around 10ish, hanna checker showed 15.9

Salinity is creeping up again.....an automatic topoff system might be needed if you can't get salinity more stable manually. Make sure you know the correct level for your tank – mark it with tape or something so you can clearly see it and don't forget. When you top up, hit that mark. You need to top up *at least* once a day. (Or...automate with a top-off system.)

im hoping to be able to save my corals.. :(

I'm concerned about the long period of 0.00 ppm in your table for PO4. Also about the accuracy of the 3 measurements in that column.

In the short term, unless you are VERY confident that PO4 levels are really rising, and really in the 0.25-0.5 range currently, I think I would recommend dosing PO4 into your tank using something like Flourish Phosphorous. Calculate a dose to reach at least 0.10 ppm. Going over is fine; better than underestimating. The main idea is that when PO4 gets close to zero, it creates a situation that can be problematic for corals.

Just a quick update on some changes..ive been tryin to get water down on salinity. Also did pick up all in reef and been dosing the 5mL suggestion ont he bottle for my tank size.
Also picked up an osmolator to get water topped off automatically so i dont have to keep doing it and missing stuff lol.

also did buy a BRS 4 stage RODI kit..i forgot to mention ive been using distilled water as top off water..wonder if thats played a part in causing chaos...oof..

BRS 4 Stage is installed and producing water! Super nervous about it but pretty self explanatory! Hopefully getting my salinity down and using some all in reef will yield good results and get things looking the way they should.
