I am a new member, I live in North Little Rock. I have had aquariums forever it seems, but being in the service for 21 years, it could never be something I would not have to tear down and sell or give away. I put a lot of time and diy into it, military people are not rich, and tried a lot over the years. I retired in 2001, and until lately, have only had three aquariums in the house, my africans in the living room, my loaches and neons in the bedroom, and my wifes community tank in the sun room. Now that my daughter has moved out on her own, I took over her room as my man cave. Of course, I needed an aquarium in there. I found a 75 at a garage sale for 25$, I bought a 40 breeder at a flea market for 20$, built a stand, bought/built mercury vapor and fluorescent lighting from goodwill. diy my 40 into a sump, built the overflow from pvc, found a good used skimmer on ebay, added two sock filters and a return pump, a six stage di/dw water filter 100 gpd. (I actually bought these new), the heater was a spare. I 3/4 of the way through my second bag of instant reef, it was at 1.020 last I checked. I have carbon pads, phosphate pads, ceramic rings, and scrubbing pads as filter media in the sump. I haven't checked the ph yet, I wanted to see what the instant reef does to that first, but I already have a bottle of ph buffer that advertises it will not let ph go over 8.3. I used filter sand for substrate, and am contemplating mixing in a bag of live sand with it. I filled it and the sump from my filter in a 1 1/2 day. It is running away, waiting for the salt to come up, the ph to be right and stable, and something alive put in it.
