Hullo folks! I believe I wandered in here originally from "The Planted Tank" forums where a link to the Fertilator had been posted. Always ready to join another forum! Got interested in planted tanks a couple of years ago but didn't have the time or money to do it "right." Still don't, but I started up a 55 about 6 months ago anyway when I had to get an emergency replacement for the 29 I had at the time. The whole process seems to have been 3 steps forward, 2 steps back ](*,) , but it is getting better. Now I'm just trying to figure out the fertilizer thingie, for someone who is mathematically challenged at best, never had chemistry, and has a memory like a sieve, it's been ... interesting to say the least!
