I'll be replacing my 55gal glass sump with a much larger acrylic sump and want to have the pump(s) external. Right now I have an in-sump Mag-36 that is feeding my main display (180g), small frag tank (20g), and 3ft 6"dia. skimmer. Here is where I need some suggestions.... Main Return Pump...

Okay, typed this once and then got a database error and lost it all. I hope this makes sense. Beginning of summer I had to move my 90 to my moms while I was caring for her because Damien was scared to care for it(the last time I left he made a honest mistake and we nearly lost everything he...

I made these Eductors out of PVC Parts for under $5, click on the link for instructions, just too much work to post it again... :) They can provide all the necessary flow to your tank, eliminating powerheads and closed loops. CLICK HERE FOR MORE INFO!!

Ive decided to locate my sump to the right of the tank behind the couch die to space constrictions under the stand. The sump end facing the tank would be 5 feet away from the return hole. I need a pump that will do 750 GPH at 5 feet horizontal and 3 feet verticle for the return. Any...

I know the Velocity T-3 is a good choice but any others or submersible ones? Looking for an 700-1000gph range. This will be a sump return. Also anyone have a place to get Velocity pumps. I can't seem to find them. Also any links to pre made educators that one can buy! Thanks

I have a 75RR with a 20g sump. I am intrested in building a closed loop for this system. I have no idea on what brand or what size pump i would need for my return pump from the sump. or what kind or what size pump for the closed loop. I will be purchasing a MR2 skimmer from MRC in the near...

Hey all, I am just starting a 75gal reef tank. Never had a SW tank before, but have had a FW tank for several years. I have been doing a lot of research and will hopefully be able to start putting this to work soon. I plan on doing nearly everything as a DIY project, and I will be needing lots...

Just that....what exactly are eductors and penductors?

i am now starting the rebuild of the Mantled Monster! i have done some preliminary stuff, but not much. the tank has been removed from its high home for now. here is a pic of the top of the mantle. i have already drilled several of the holes for the 2" drains and returns. that long metal...

I'm looking for a deal on an external pump for an upgrade on my remora. I understand that the Mag 5 has been tried and found to be the highest flow this skimmer can use. Does anyone have something I can use? Thanks, Dan

I currently have a CPR CY194 12 gallon sump with 6" diameter skimmer built in. I have a Mag 18 (1800gph) return pump that pushes the water out of the sump, into a 40w UV sterilizer, then into a 1/3 HP chiller. There is a total of 11 feet of 3/4 PVC pipe, these measurements include the sterilizer...

How much flow (in gph) would you recommend as good flow from one side of a 72" to the other? I'm trying to figure out a good size powerhead that will push that much water. I would like to install 2 powerheads in an X formation, one in the top rear right pointing to the bottom front left, and...

Hi, still deceiding what type of set-up my final tank will have, but a sump seems to be the most popular & recommended method & therefore may have to make an acrylic sump, that Im sure can be that hard & at least it will fit inside the cabinet. Anyway, what I need to know now is what skimmers...

HI im new to the whole reef tank thing i am looking to buy a protein skimmer or building one I have a 20 gal with a 15 gal sump that just finished cycling. I have been searching local fish and petstores and on the net for a good protein skimmers. I want to have soft and hard coral eventually. I...

i went to a lfs with my tds pocket probe and got 45 gls of water. i measured the water and it came to 210-220ppm. there method of filtering water is called "cold sterilzation" (neva-eva herd of dat!). normally, i can get <10ppm from my own ro unit, but it doesn't produce the volume i need. but...

Well 2 weeks and we get no new thoughts. Thats it? nothing left to talk about???? Spanky get busy boy, no slacking now. MIke

ok this may be one of the easiest DIY projects i have ever done. i have made 3 different sizes. 1/4, 3/8, and 1/2. they seem to be working but i would like someone else to give them a try. i am running the 1/4 and 3/8 right now on a mag 12. i know this can pump out enough and they do seem to be...

I found this link from the DYI section on an item called "eductors". It is a very simple way to increase the water flow from your pump returns. It boosts the pressure and volume of your existing return without electrical aid. The website said they are used in shrimp hatcheries and chemical...
