420_sci I would like to pick your brain if I could. How long would it take a pump with 2-3 air stones (regular ones I assume w/ about 6-8 sq inchs of surface area) to properly airate a 20 gallon resevoir? I tried to introduce airation into a system and found an increase in slime build up but I was leaving it on 24/7. Would it help to run the airator only when the plants are being feed? Any tips in this area would be helpfull. |
