Don't you have an asphalt substrate
Jamie, no I don't have an asphalt substrate, :doubt:
I do use some asphalt as live rock. As a matter of fact I am mailing a piece of it to Mike today to analize. Asphalt and RUGF's seem to be two things that you can't put in a healthy reef tank. I don't let my tank read this stuff so it doesen't know it's supposed to crash. :badgrin:
I have also used UGF's on fresh water for many years and you are correct they accumulate detritus and stink forcing you to tear it out to clean. I really don't know why this does not happen in my reef but after three decades of experimenting and tweaking it I have it down to a science.
People have been giving me all sorts of scenarios and excuses why my tank hasen't crashed so far but I don't see any problems surfacing yet. I can, and do re-aquascape when I get tired of the look, maybe every five years. I can remove the rock and stir all I want with no problems, I was thinking of rearranging this week. I run my RUGF very slow with a sponge on the intake. I don't need to quote articles on the pro's and con's. There are no pro's that have a reef this old so there is nothing written on it. Bob Goemans came to my home about ten years ago to see my tank and although he was impressed, he also had no Idea why it ran so well. I know very little about DSB's, no need to, I like my "Old technology system".
I know they can work very well as most of the people here seem to have them. Ugf's are very old technology advocated by Robert Straughn (The Father of Salt Water Fish Keeping) in the early fiftees. He dident exactly know why they worked but he knew they worked. RUGF's are not old technology. There were no reef tanks then but when reefs came out in about 1980 or so (well kind of reefs
We had to change the functioning of the UG filters to adapt to the more stringent water parameters of reefs. We also didn't want to remove the rock to clean anything the way we could in FO tanks.
I am not saying this is the best system. I couldn't say that because I am not an expert on the other systems. I can prove that a RUGF can work with almost no maintenance and work very well for at least 35 years. My reef is far from perfect, if it were I would put something in there like shreaded bowling balls so after another 35 years I could debate the pro's and con's
Have a great day what ever system you have, I still love you. :lol:
