Hi all, I have a 24 gallon/90 litre sumpless, skimmerless, and refugiumless tank and zero phosphates.
My levels are:
Kh 7.7
Calcium 420
Mag 1320
Temp 78.8
Ph 8 (I dont chase this)
Nitrates 10-15
Phosphates 0
Salinity 1.026
All test kits are I date salifert kits.
The issue I have had, was major growth of digitata for a good year and a bit, then alk and calcium consumption stopped, the digitata paled then died ( I'm assuming phosphate limited). This led to a cyano outbreak which I treated with red slime remover, that is now gone.
To my current issue, I am feeding heavier to get phosphates up and the lps are looking better though not the best they have, i dont do big water changes maybe 10% every 6 weeks.
The remnants of the dead digi are growing again, this is a good sign.
But I do have a little dino on the rear filter box of the tank. With feeding alone I'm not getting a detectable phosphate, so I'm looking for advise to dose phosphates in the form of a diy solution of monopotassium phosphate at a ratio of 5g to 500ml of rodi, 1ml of this solution, from what I understand will raise PO4 by 0.07 phosphates and 0.04 potassium per 100litres of water.
I would like help in how much and how often to dose a 90 litre system please.
