The AF guide says PO4 0.01 to 0.04ppm and nitrate 0.1 to 0.5ppm for SPS dominated systems. Both of these are measurable by hobby kits. Another thing AF guide says and highlight that limiting nitrate is not good for the system so if it read 0 you should feed more. To be on a safe side targeting 1-2 ppm is better as you have a margin of error.

what I am trying to say is that with common test kits having zero at the results don't mean that you have zero No3 and Po4
Most common hobby kits like you said can go so down but are limited on their accuracy .
Some example of the most common brands used in hobby.

Redsea kits
No3 Accuracy 0.125 ppm
Po4 Accuracy 0.02 ppm
Hanna kit
Po4 checker Accuracy ±0.04 ppm

Best way to have a clear statement is still the ICP test

The point is with Hanna ULR you can reach more resolution. Second, with red sea if you dont measure or measure 0 then with accuracy taking 0.125 ppm above its still count as low and by chance if its even less than zero then its worse. As far the ICP testing goes it costs $50 per test and I dont think for a regular hobbyist its possible to spend that amount every month.....

@eg8r210 So you run one or the other right like the other zeo systems to obtain ULNS,
How much zeo is needed for a 140 total volume and how often do you change

or run phos minues

I run both. In my 300 gal system I run half the bucket of zeo/phos minus/carbon. All three go in one reactor.

So I will have to bring AF into this one, as I am unaware of what may be contributing to nitrates in salt. The lab is in Poland, they test and produce the salt there, I only can provide user support. I will alert someone to this thread @Debora Dlugopolska

@sever10 can you provide input as to why the test above analyzed with nitrates 2.5ppm on newly made saltwater using Reef Salt? Cheers

Hoping you guys can offer some help. I posted this on the Aquaforest forum also....

I was hoping you could help me out with a dosage question. I'm going to be starting my 3 part dosing this weekend. I was looking over the recommended dosing and it says for component 2+ (Component 2+ contains: NaHCO3, F, I ( 50ml raises the KH of 1,3 dkh-Alk 0,46 meg/l in 100l ).US: ( 1.70 fl oz. raises the KH of 1.3 dkh(Alk 0.46 meg/l in 27US gal.). My system is about 160gal total, I've been using BRS 2 part for Alk/Ca replacemtent. Currently I add about 80mL of Alk daily to keep my alk at about 8 dkh. I test every morning and Alk is always at about 7.3dkh, so on a daily basis I am increasing the dkh by 0.7. For the life of me I can't figure out how to calculate how many mL I will need to dose. somebody please help. TIA

I would start with the same 80 ml dose and adjust from there

Thanks jsker!

 

[jsker]

Thanks jsker!

Start all three at 80ml, you make a few adjustments. I am at 80 gallons water volume and my 1+3+ are at 43ml a day and my 2+ is at 42 ml a day

Based on their dosage calculation, for every gallon of water you would need to add 0.145 ml for a 0.1 dkh increase. So for 160 gallons to increase 0.7 dkh, you would need to dose 163 ml (160 x 0.145 x 7).

When I switched from BRS 2 part, I found out the dosage was about the same.

Great! Thanks for that feed back.

I have a question regarding some products. I realize that some of them state that dose when lights are off. My lights are never completely off. I run my lights with a sunrise and sunset setting. So at night that usually at 9% max depending on the lunar cycle. Can I still dose or is it recommended to have the lights completely off?

 

[120reefkeeper]

To be honest.... I dose my stuff with lights on ... off... in between... lol [emoji23] [emoji12]

The "night time" dosing products are mainly due to sps corals having feeder polyps out for food gathering. Your "night time" setting are fine, I usually dose about an hour or so after lights out with Energy, Vitality, Build, and Amino Mix. I pair the Energy with Build and alternate days with Vitality and Amino Mix. I usually dose NP Pro and Pro Bio S first thing in the morning, just a method of routine that I have employed that seems to work

Thanks very much. I completely understand now.
