needle valve

I ordered a Aqua Medic SP 3000 for dosing Alk. I'd like to slow down the rate since I can only find digital timers that go down to the minute level (and not seconds). I was thinking of using a needle valve. Should I place the needle valve before or after the pump? I would think after the pump...

Can anyone tell me where i can get a co2 needle valve (coupler )to purchase coupler only.

Hey all, I have a Reef Fanatic CO2 regulator which is a year old. This is the type which does not have an adjustment but is automatically set to deliver CO2 at a set rate to the needle valve (think no separate regualtor knob to adjust back pressure). Until recently, I had no difficulties. A...

Well! The Solenoid on my CA reactor has jammed wide open once again,.. This time luckily I was home, and I had set the bubble rate to almost exactly what was required, so we didn't have a re-spin of the previous problems and Alk spike to 22DKH. The first time the problem was the innerds were a...

I just purchased a CR-140 for my tank and got it all setup, however the pump is making a fairly loud noise especially compared to my Eheim pump, almost as if the impeller is misaligned or it is bouncing on the bottom of a tank. Has anything had this problem? The pump is labeled as an "Octopus"...

Ok I need to start running Kalk BC I'm tired of dosing every monring and it's getting REAL expansive. I'm going thru a bottle og Liquid reactor a week :bawling: Right now I'm using a kent float plumbed to my RO/DI. I know you think is a accident waiting to happen but I've been like this for...

LONG Story short: Had a lower bulk head leak and had to drain my tank. So I took the opportunity to clean everything up and re-aquascape. Much more open now and no rock touching the glass so I should be able to keep it alot cleaner. Much better flow aswell. So here it is BEFORRE: and...

I am getting out of the aquarium hobby for a while. I have some other hobbies I need to focus on so I need to address those. I am initially going to sell the stuff I am not currently using on my running system. l will eventually start selling off my running system once some of this other...

YES! I have official began my build. I am upgrading my 75 gallon. I will post some pics of the room that I am partitioning off and what the plan is. -I ordered the tank today. Will be here on Friday (I know, quick huh) -Will get a hundred pounds or so of live rock on Sat. -Bought an...

Programming my AC Jr... anyone willing to come help me with this thing?

I had an issue with my CA reactor about a week before I left for a trip to Vegas,.. the regulator was being in-consistent and would sometimes push the PH in the reactor WAY low making the reactor really supplement my tank. I tested my ALK at 16DKH. I shut the reactor off, let it drop, fired...

Maybe someone can help me with my drains , I have a 150 with two overflows . The thing is the drains are in the side panels of the tank (came that way I didn't put them there) and their about 3/4" from the trim that goes around the top of the tank . They are making so much noise that I had to...

I have an overflow rated for a 75 gallon tank and a Cap 220 return pump. I have been running flexable hose for my return (untill this weekend). My skimmer sits in my sump. My return pump is located in the last chamber of the sump. The water from the return and skimmer has to go thru the...

I got a guy who can get me clear pvc, probably free in any size and length I need, but he needs my specs, I will offer to make him one also, if he wants. He tried to make one once he told me with a airstone design and wasn't happy with it. I am going to mod this design...

I have a Gen-X CO2 regulator by pacific coast imports. It has a solenoid and a needle from MRC http://www.myreefcreations.com/caaccessories.htm at the bottom of the page. Currently the regulator is putting out an output pressure of 25. That is just a touch higher than I want. There isn't any big...

I am setting up my calcium reactor. I don't know if its just that I am tired but these instructions for my pinpoint PH controller suck. I have it calibrate. I want it to controll my CO2 solenoid. I want it to have a centerline of 6.8 with a range of +-4. 6.6-7.0 according to the MRC...

Still contemplating my skimmer build, I like this design, seems the easiest to do and am thinking of going wider as opposed to higher. I would like it to be overpowered for my tank, figure good for a 250g tank (I have a 90 now). Also what size pump/ph woudl I be looking to use. I have a...

I'm looking to buy a calcium reactor for my 125. What should I look for if I buy new? Used?

Hey all, Anyone have good recommendations for a CO2 regulator (which obviously means one which needs little fiddling to remain constant and reliable). I have had it with my current on and it's time for it to hit the trash can. The needle valve stinks as well (possibly damaged before I got it...

Okay, here we go! After some long planning, timing and decision making the time has come. As promised, I have already started to get things going this past weekend and will have descriptive details and pictures through my every step. (As we all know how much everyone here loves pictures!)...
