They're good for appx 40 gals of clean water before the filter needs to be changed. I would not advise using epsom salts full time for PH adjustment. I would also advise picking up one of those cheap PH testers to make sure of the content...both ASAP.

Good luck!

What? i was under the impression brita water filters did close to nothing for hardwater, also the ph has nothing to do with an Mg def.

Good call on the epsom salt i too have hard water, loads of calcium is the problem. my water is at 220ppm from a well. Your best bet would be a r.o. system u wouldnt need a very expensive system just one that helps out a bit, or u could just add alittle bit of epsomsalt every res change. To be honest the only time i noticed Mg def. was in the early stages of vegg, once the plants get big they love the hard water. When i say my water is hard i mean there is calcium deposits on every source in my house of water. But then again i havnt used the epsomsalt in months so it varies from strain to stages of the plants life, early stages u would be worried as it gets big the worry will leave u'll see, this isnt something u have to fight the whole grow just the beggining. I happen to think the hard water is good for the plant once it starts to flower, unless its not from a well, well water ussually has a chit load of mineral and stuff thats great for the plants.
JackdaWack Reviewed by JackdaWack on . help with fixing mg deficiency have just figured out my main problem is our water supply in the area it is very hard so have just added 3/4 tsp of epsom salts to 3 litres of water what i really want to know is roughly how often should i put the epsom salts in the water should i do it all the time like mix it with nutes also or just once a week really desperate to try & save remaining 2 plants as seeds are almost impossible to come by where i am:hippy: Rating: 5
