DSR Fe + (iron): PO4 Remover

DSR Fe + is used as a phosphate remover (the effect as a trace element is negligible)

The active iron in DSR Fe + binds with Phosphate and precipitates. The precipitate can express itself in a light haze in the water that will be filtered or skimmed off again. This can be recognized by the rust brown drab and the black water in the skimmer.

Due to the slight haze, Fe is best administered overnight around 11 p.m.

Phosphate can best be controlled at a level between 0.04ppm and 0.08ppm
Lower than 0.02ppm causes the bleaching of coral. Higher than 0.12ppm will cause brown corals and on migrating tissue loss. In very sensitive acroporas, the tissue itself can release spontaneously.

Up to 0.24ppm a daily dose of 0.15ppm Fe + per day will suffice
above 0.36ppm, a 2x daily dose of 0.15ppm Fe + per day (12 hour interval) must be assumed

The chelate part in the Fe + iron supplement also works as a carbon source and as such also reduces nitrate and phosphate. Something to think about. As a result, it may be possible that nitrate must also be administered to keep the nitrate stable at 1-2.5 ppm.

Warning for sensitive animals:

Some doctors, emperors, coral butterflies and tridacna species are very sensitive to iron dosing. So pay extra attention when dosing Fe + and build up the dosage slowly. Dose a maximum of 0.15 ppm in one go and the measured value must never exceed 0.25 ppm. For the most part, Fe + is no longer measurable after 4-8 hours. If you wish to check the dosage, this can be measured after 20 minutes. Make sure that your skimmer works properly, because a brown rusty sludge is created which drains your iron with bound phosphate. Since iron reacts with various elements (including PO4), it is normally not feasible to maintain this level continuously. The main purpose of measuring iron is to prevent iron from building up to a harmful level. Once it has been determined that this is not the case, the measuring interval can be reduced, the lower the phosphate, the greater the chance of the iron content building up.

Phosphate is absorbed into the rock, the longer it stays in it and the higher the content, the more phosphate is bound. This works as a buffer. If the phosphate is removed from the water, the phosphate will leak out of the rock, therefore the one-off removal of phosphate will not produce an effective result. By first removing the surplus in the water with the initial dosages, this will eventually also be bound and skimmed off when the Fe + dosage is maintained. Daily and gradual dosing results in a descending line of the phosphate from the start.

The advantage of a liquid phosphate remover is that the dosage is constant and controllable. With fixed removers, the media becomes saturated faster as the PO4 level is higher. You have to keep this in mind, otherwise the value will rise again.
Because of the buffering effect, the phosphate can measure high for a very long time, and suddenly it can go through to immeasurably low. it can also measure zero and again measure too high a few days later. We have to think about this

It is best to build up the dosage from 20/40/60/80 to 100%.

day1 = 0.03 ppm
day 2 = 0.06 ppm
day 3 = 0.09 ppm
day 4 = 0.12 ppm
day5 = 0.15ppm max. dose / day

Accelerated build-up dose (with extremely high PO4,> 0.64ppm)

If you have a phosphate problem you can build up more quickly with doses per 12 hours: day1 = (20 + 20), day2 = (40 + 40), day3 = (60 + 40), day4 = (80 + 20), from Day 5 = 100%.
day1 = 0.03 ppm, after 12 hours another 0.03 ppm
day2 = 0.06ppm, after 12 hours another 0.06ppm
dag3 = 0.09 ppm, after 12 hours a following 0.09 ppm
day 4 = 0.12 ppm, after 12 hours a following 0.12 ppm
day5 = 0.15ppm max. dosage / day and this can also be dosed every 12 hours.
Once the phosphate starts to fall and falls below 0.08 ppm, transfer the double dose to a single dose.

You can convert PPM to milliliters with the DSR calculator.
(Download here http://dsrreefing.nl/forum/index.php?topic=385.0)

To do this, enter the contents of the container, set your measured iron value to 0ppm and target value to the desired dosages. (or you set the target at 0.15ppm (100%) and count from 100% back to the other percentages)

With the calculator version v141122nib or later, the target value is determined on the basis of the measured phosphate value. With high phosphate this is 0.15ppm (you use Fe + to lower phosphate) and with low phosphate this is 0.02ppm (you use Fe trace as a trace element)
