I am just starting up my dosing regimen and I need a little help on a few things…
Out of the tap my gh and kh are both 3. They stay at 3 even in the tank. I’d like to raise it 1 or 2 degrees after water changes to keep my co2 around 20ppm. (6.8-7.0 ph pressurized co2)
Am I better off just dosing calcium carbonate instead of crushed coral in the filter? Can you only dose calcium carbonate once a week at water changes and still keep it stable? (really don’t want to test more than once a week)
Ok secondly and most importantly
Phosphates out of the tap are .25 (testing with crappy red sea test kit)
After testing the tank it seems to be 2+ all the time (you have to look down into the test tube to compare.. really hard to tell)
I’m guessing it’s the fish food that’s causing the phosphates to be so high.. even after 50% weekly water change it still registers off the chart
I rotate freeze dried blood worms and “tetramin(full-o-phosphate)flakes” but I’m not sure if they can cause it to be so high..
I even just fed just the worms for a week to see if phos would drop, but it didn’t…
Should I add some kind of phosphate remover media to the canister or just bring nitrates up to 20ppm?
And one more question…
I have a 55 gallon tank
I’m dosing plantex+b every other day… 500ml water 2 tablespoons
I’m a little confused… rex griggs site says .5ml in 20 gallons, other sites say 5ml
Is the period a typo? 1.5ml liquid seems like it’s way too little
Any and all advice would be greatly appreciated.
