hey folks...ive been lurking for quite a while and now ive got my 37 gallon sw setup. i cant wait to participate more regularly in conversations, and im sure i will. i got the water in the tank two days ago and since i have added 12 lbs of live rock (two small boulder size pieces). i plan to add more rock, but the dehydrated so that i can spend less on it. i put 40 lbs of sand in the tank but i think my bed may be too deep so im taking some out. right now the depth is between 3 to 3 1/2 inches and im going down to between 2 1/2 to 3. my light is a t5ho 30" with one white and one actinic (sp?) bulb. im also using the marineland biowheel 200. i will get the powerhead in the next week or so but since i have no fish or havent completed my cycle yet, im saving to buy a little nicer one. my heater seems to be working pretty well, pretty acurate on the dial compared to my thermometer. i dont have any testing supplies yet, but thats coming this week too. i did already buy marine buffer thats supposed to be guaranteed to buffer ph to 8.3 and no higher even if overapplied. i also put this biospira (little purple bottle) in today. i wasnt going to use it but i decided to since i want the cycle to take the least time as possible. ive seen good reviews about the stuff too. any comments or suggestions are greatly appreciated.
