I’m attempting to bring my diatoms down and purchased seachem phosguard. It says it treats 60 gallons. Is it too much for my 29 gallon? Phosphate levels are right around 5 and clearmax doesn’t seem to help anymore
I have used it before on saltwater tanks. If I remember dosing correctly. 85ml phosguard (1/3 cup per 200l salt water/ 400l fresh. So you will need to do some maths. Better to under dose and test regularly.
I just dose and test po4 every week or so. When it starts rising I redose with new. Think it can be recharged and used again though.
