Yes, that's the right spectrum and should work fine. The more watts the better though. I assume you mean macro algae when you say algae?

I own 3 of them. I have two on my closed loop and another on my sump return. IF you regularly clean them(soak in vinegar every couple months) they will not fail. Ca will build up in them if you don't clean them, which will stop the gearing mechanism that enables them to switch outlets-that is...

For a nano I'd get a 70w MH retro for around $100. I'm pretty certain you can hang the reflector. Google: sneggs or DIYreef and check out the retros.

No, unfortunately it won't work. You can buy a 250w magnetic MH ballast for around $60. A spider reflector will run around $20, and any decent MH bulb will be at least $50. A socket and cord will run another $10. Then you will be good to go as a retro as long as you have a canopy already. Of...

Originally Posted by SaltyCrab I cant tell but it looks like you may be considering having a drain feed the skimmer. This is a bad idea. The skimmer should be feed from the sump. Why is this a bad idea? How you have it set up will not work. It's possible to use more than one return pump, but...

If you don't cook baking soda it will actually lower your pH. Cooking baking soda releases the carbon dioxide. Washing Soda on the other hand will work fine straight up. First though what is your Alk? I would not add cooked baking soda unless you know your Alk is low. Otherwise you will...

Some older shots. The orange cap was huge, he took up almost the width of my 55g so I had to trade him into a LFS here. Second shot is a green cap with purple rim. Fourth pic you have to look at the very top to see the orange cap.

I would never try to plumb an ASM externally, they are notorious for leaking...

Depends on your Macro. Chaeto-fast. Caulerpa-slow. Most people realize Chaeto is the better macro, so taken as a general statement-fast.

I too did Vodka and Prodibio, but for PO4. Neither worked. A fuge would be my first recommendation. Before I installed my fuge my nitrates would run around 10. After I put it in I never had a problem with nitrate at all. I use a moddified Octopus NW 200, with 110 lbs. LR and a DSB. The DSB...

How old is your LR and if you have a sand bed how old is it?

Very nice tank. Is that a Bali Green Slimer with blue tips in the upper left of the photo?

Yes it's fine for LR to be in total darkness 24/7. The process of cooking live rock involves putting the rock in total darkness for several months to rid the rock of PO4 and other nutrients. Darkness leads to a bacterial driven environment instead of an algae driven environment to force the...

I'd assume your salt is the culprit with those readings. What brand of salt are you using? My guess would be Oceanic. I'd be certain your Alk is very low if your Ca is that high and pH that low. Water changes are the easiest way to lower Ca, but I wouldn't do too much at once(more than 50%)...

A refugium is nothing more than a separate tank plumbed into a DT that is free from predators. In it's truest sense it is specifically for the purpose of growing pods, mini stars, and other critters as a food source for your DT. Therefore to be a true refugium it should have no light if your...

If you just put this skimmer in your sump today, I wouldn't expect to see any skimmate until a week if it is brand new. If you ran the pump and skimmer in vinegar water for a day or so to begin with, it will skim right away in SW. But with left over oil from the skimmer build still present, it...
