I remove the tubing and submerse it in the sink/bucket of hot water. The deposit will be salts so I figure the hot water should dissolve them. Mine haven't really been dirty enough to need anything other than warm water.
No I don't add anything but the salts. Make up 1l at a time in RO, used to use cooled boiled water though. Never changed colour or had any precipitation that I've seen, but I always mix up in a separate mixing bottle and leave for a few days.
I use the same ferts from apfuk and its strange that your macro is the same colour as my micros mix. My macro always has been completely clear whereas the micros are a tinted colour.
Im not sure but I'd probably pour it away and make another batch. [emoji106]
I've added several cable ties to the parts above and below where it joins if you see what I mean. Regularly check for flow problems ie on water change day, and all seems to be working fine.
Also, don't know if you are but I'm using co2 resistant tubing not airline tubing. Been running for 8...
I've foolishly ran out of my MgSO4 for my EI Dosing.
Until I get a new delivery of salts can I use some epsom salts I have left from my past Malawi cichlid tanks?
Pharmaceutical grade epsom salts. I'm thinking yes but wanted to double check just to be sure.
Just a little curious if the bottle of my dosing bottle is normal. Just refilling them and it seems to have stained the bottle.
Is this effecting the ferts going into my aquarium at all?
