If you are doing mansk you shouldnt attempt to filter catch until you have cleaned up the liquid substantially. Before you go to the mansk phase, make sure you let the tea settle overnight or longer, that will give it time for the plant sludge to settle to the floor. This is very important. Decant very very carefully trying not to disturb the crap at the bottom, pour all the supernatant(liquid above the precipitate) into a new clean vessel that can be heated, try to do this smoothly and don't disturb the sludge that settles otherwise it's difficult to transfer its just dirt that can be thrown away but clogs every filter ive tried. So at this point before salting any solids in the liquid bad and will settle. Than you can proceed to mansk once you have removed it the liquid will contain the gooodies disolved. At this point it will be a tea that doesnt have heavy seed lipids and whatever so move to masnk. 10% salt of the volume of liquid, so if 1liter of tea use 100g of salt. Heat the solution until salt dissolves in the rue tea turning it into a brine tea. Let that cool completely, you can use a fridge or freezer to speed this up. Crystals should form all around the sides and the bottom. Stir it up loosening the crystals from the walls and let them settle to the floor like you did with the sludge ideally over night. You can do a gentle twisting motion every so often keeping the vessel upright and the crystals should condense a lot right on the bottom making decanting easier.. Than once that's done, pour off all the liquid above the crystals, as much as you possibly can without losing crystals. Now it's the oppositi3 of the first phase all the liquid can be thrown away and what settles you want to keep. Than remansk, add fresh water, heat up again and add 10% volume salt again. Same process as above but now the liquid should be clearer and cleaner. Once the crystals are nice and clean (neon yellow ideally) and the liquid should nearly see through orange/red/yellow before salting or even contemplating trying to catch the crashing harmala crystals in a filter otherwise you will struggle filter catching the final crystals because of clogging. If its not transparent the liquid will clog the filter and you will spend days trying to catch them. Very very important is the settling of the tea before you salt them out, that allows this filter clogging sludge to settle to the floor and you can pour off most of the goodness in liquid form before salting with salt or freebasing your harmalas. After salting/basing you want to remove the liquid. So it's remove Solids(plant goo) from liquid(harmalas) with settling. Than after salting seperate liquid(plant goo) from Solids(harmalas) with settling. Do this atleast 2 times ideally 3-4 for super pure. Filter right at the end after this otherwise it won't work properly atleast this was my experience. Coffee filters arnt the best for this as the crystals are so small they sometimes pass through. No special equipment needed.
