It works rather good for the moment - since I discover that I could not relay totally (and absolute) on my Hanna Checker.
I dose around 0.06 ppm PO
4 a day for the moment - taking out the PO
4 remover and feed with 5-6 frozen cubes cyclops and 2 - 3 cubes adult artemia every evening.
Still have some cyanobacteria in places with low circulation.
I have to clean my windows 2 - 3 times a week - otherwise I have at the start a film of green algae on the window - but that´s only the in the start - this window was cleaned totally 2 months ago!
I have a montipora that grow close to my left side panel and if i do not use my algae scraper in the gap between the coral and the side panel at least twice a week - I have problems to pass the gap with the scraper
Two weeks ago - I took away some parts of this montipora because it was too large and shadowed corals behind it - it looks awful as usual but today it looks like it should - the growth make it look natural again.
The lesson learn - all of our test equipment is of hobby grade (good hobby grade - but still hobby grade) use it not as the whole truth and not either as the whole likelihood

- use it as a tool among others. It was not long ago I complain over bad growth and not healthy aquarium - all my test show nutrients enough - most biological life said that I had a nutrient problem. I could not get down the PO
4 with GFO and Al based media - it still show around 0.1 ppm PO
4. I reacted on this - should have reacted more and first after a Triton test - I realized for sure that I was low in PO
4. I´m going to send in a new Triton today - but I will take the sample after my peak pH in the evening. My goal is 0.04 - 0.08 ppm one hour after peak photosynthesis. I use my pH as a tool to determine when have the peak of photosynthesis. I have also change my way of dosing PO
4. I have a reversed refugium (not so very large) and during night - I do not dose PO
4. I´ll dose it during time that the corals need it instead.
