Drip system?

I've just got a new drip system and it has an 80ltr tank, how often should i change the water, an should i clean the tank every time i change the water?

Thank's.

Every 7 to 14 days. How many gallons is that ? You need an RO water system.

How often are you running that system? I've heard of many schedules that people have so I'm rather confused on that...
Thanks

For a simple drip system I leave it run 24/7. I have done this about 6 grows now with no problems. Schedules are mostly for NFT type system or areo cloners. Show us a pic's or show where you got it, it will help just to make shure.

Loc is on target...you have approximately 20 gallon rez

mix your nutes at beginning of feed cycle and when you top off rez...use plain ph'd ROwater, or *distilled water

thrifty note...*I paid for my RO unit in 3 weeks as opposed to buying 30 gallons a week...they sell on ebay for about 90 bucks.
