I have now come back to my most favorite hobby after being away for 15 years and I'm very eager to dive deeper. I'm having a dilemia about the what i did then and whats available to me now. Back in the day, I had a 125 gal. FO tank, No live rock, no berlins, no fuges. In the last five months, I have spent at least $400.00 buying books and magazines for some light reading, and i have wore a hole in my mouse pad searching and reading. I used to run an super high flow reverse undergravel that was prefiltered, You could almost see the gravel floating on the bottom. This tank was OVERSTOCKED by many inches of fish. At the end when i had to sell it, i must have had 20 large fish in there. At that time i used a Fluval 203 and a maguum 350. The fluval was packed with alternating layers of chemi-pure and and Real Poly Filters. When people saw this tank, they thought it was fake, because the fish almost appeared to be floating in thin air. the water was so clear. I ran the micron catridge in the maguum. Along with the UGF, i had a six foot tall acriylic tower 8" in dia, filled with the original Dupla Bio-Balls, with a old powerhead to a small drip plate and then pumped out by a matching pump(worked great). To my point, that fish tank ran and ran, through ice storms to no power for three days, to torandos 7/21/89. I rarely lost a fish, and it was sucessful for some six years until i sold it when i relocated. I believe good husbandary skills are by far the most important single item that will make a tank suceed. Now the question, Can i still use my some of my old school ways that have been tested and suceeded on my soon to be new Reefs. I don't see anybody using these products anymore,ChemiPure and poly filters were cutting edge back in the day, and i don't see any products that can clean water better, I'm i missing something?. Having visited and seen hundreds of pet stores over the years (gotta stop whenever i drive by one, I'm worse then a woman in a shoe store), I can say that very few tanks i have visited, few had that sparkle to the water.Any thoughts? 8O
