Can a standard 55gal glass tank be drilled for bulkheads? I need to switch to a new type of main pump on my 180gal reef tank ASAP. It went out tonight and I have nothing on hand to cycle it for now. Hopefully the 4 powerheads will maintain it in the meantime. I'm not feeding the tank and will keep...

I have a 155 gal tank. with a 40 gal sump I would like to increase the sump volume, how ever I do not have room under the stand. I would like to add a second sump (6o gal) with will be remotely located (outside in a shed - temp controlled) I would need to bury the plumbing (under a walk way) I...

Are they good for tanks or do they destroy live sand by eating everything in it?

I have read about decapsulating of brine shrimp eggs in http://www.advancedaquarist.com/issues/dec2002/breeder.htm They say: "These decapsulated cysts can be hatched into nauplii immediately, or dehydrated in concentrated brine solution then stored for later hatching. Lastly, the decapsulated eggs...

I just upgraded to a 100g acrylic. The plan was to use the 60g as a sump - it's 2" too wide to fit under the stand. So I got to sell it. I'm in Orange County. Asking $150 OBO. Also I have a 6ft tank stand that needs to go as well - $40 OBO. (sorry about posting this here but I have to get rid of it...

Hi Everyone, Can somebody tell me what redox potential is please? Thanks in advance. Paul

Hi I need to buy a water pump and some other stuff, and the prices here in Europe (Portugal) are a lot higher than in the us. Can someone give me good references of an online store that ships to Europe? Thanks Jose Marques

I have a buddy who is moving and is offering his system to me. It is about 40 gal, 30"x12.5"X25" and has the stock 2X18w lighting (Eclipse system 3 I think they call it.). He has some live rock and sand and a fwe small damsels in it. I'd very much like to get back into the hobby and I know that...

Sorry for the cross post, really getting desperate. Had an order half filled by Aquadirect early last week. My wife has left a few phone messages and e-mails to see about the rest of the order but non have been responded to. Buffers are getting mighty low by now. Anyone know if they closed for a...

How can I accelerate the growth of that yummy green stuff ? I currently have it in white 5 litre buckets and one 33watt fluro over the top, it grows well, but slow. If I empty 1/2 a bucket into the tank and top the bucket back off with tank water it takes about 1 week to get back to where...

I am curious if anybody was thinking about it, what is the accuracy of measuring Ca++, Mg++, Strontium, alkalinity, phosphates, ammonia, nitrites, nitrates - not mentioning pH tests? I was looking for this info on the boxes and literature which comes with the tests and I have found references to...

anyone use any night lights as I remember someone telling me there are very few dark nights on a reef. it's just my algae seems OK when the lights are on but first thing in the morning the brown scum is back on the rocks and gravel. I have 8 red legged hermits but no turbo snails, should I buy a...

I saw this on Ebay the guy claims it will remove unwanted fish. http://cgi.ebay.com/ws/eBayISAPI.dll?ViewItem&category=66795&item=4309000106&rd=1 I was interested in seeing what it looked like. I thought that the picture was so ugly, maybe he thought it would make the unwanted fish jump out in...

I am looking for some creature that is reef safe that will eat hair algae. I have some damn damsels, yellow tanks and variuos hard/soft corals. Some hermie crabs and snails Any suggestions? Thanks Mc

I am setting up an undrilled tank for my son and am looking for recommendations. He wants to have some corals (still undecided what types at this time) I want to know my options. We have tried tanks with a hang on over flow with bad results, so I want to stay away from this. I am not sure I want...

I have a H. magnifica that periodically wanders, including time spent on the glass. Not a good look. I've tried to make a nice reef for it and varied the 175 10000K MH location, to no avail. Yesterday it was on the glass, this morning it was back on the reef. The biggest problem is...

I have noticed my PH going down from the normal 8.2 at 10AM to 8.4 around 11PM for the past 4 years. But over the past year my readings have slowly gone down to 8.0 at 10am to 8.2 at 10PM over the last 6 months its more like 7.8 at 10am to 8.0 at 10PM. I recently did a 200 Gallon water change and...

(posted this originally on rec.aquaria.marketplace, but thought I'd post here before I dispose of the shrimp) Caught a Mantis shrimp a couple inches long that was terrorizing my tank, and was wondering if anyone was interested in a trade (or sale) for the critter. I live the Chicago area and...
