King British Ws3

[arnt rams great]

Hi all, Im new to the forum so bear with me.
2 saturdays ago I bought 2 ram cichlids, which are lovely, eat well and seem relaxed but have started with what I think is Ich (not something I have had experience before)
Now for the daft question;
I bought WS3 as recommended elsewhere on the forum. It says to be accurate with the dosage and says use the pipette but the pipette has no measure marks on it, how much of the pipette needs to be full for 1 mg.
I have clown loaches and shrimp in the tank as well.

The tank itself is a 90l aquaone 620

Put the end of the pipette into the WS3, squeeze the bulb on the end and let it fill, that is 1mm of liquid.

use a syringe there easier to use and you know exactly whats going in

having clown loaches should I be putting .5mg in at a time?
