Thanks for the reply, i'm pretty sure the tank is cycled, I used a raw shrimp to start the cycle a couple of months ago and saw an ammonia and nitrite spike at which point I added the live rock (which was cured) which reduced these to 0 after a few days, the nitrate has been reducing for the...

Hi all, I haven't posted on the website for a while as I have been keeping freshwater tanks, but I have recently started a new SW tank and have a couple of questions, my tank is one one of those plug & play style nano's (15 gallons), the built in skimmer is useless though so i'm not using it...

Its not coralline, I had that on my glass/rocks too when my tank was new, I found turbo snails eat it (I hated the stuff).

not familiar with that filter but if doesn't have any you want to put a tap on the intake and return pipe, otherwise water will siphon from the tank when you remove the cover.

anyone know?

You can use NO fluorescents on SW tanks, in fact the corals in the picture for my avatar are growing under nothing but 2 white and one actinic NO fluorescent tubes, in fact the coral on left has doubled in size in last 4 months or so since I got it and is now at least a foot in diameter...

can you wire two fluorescent tubes to one starter unit? for example could I wire two 18" (15w each) actinic tubes to one 30w (or above) starter unit, only it would be easier to manage and cheaper than buying another starter unit and would mean less wires to plug in, cheers. :D

That's what I'm thinking, the only high lighting thing I want to keep is a BTA, but I would of thought it would do ok high up under 150w, the rest would will be mostly soft corals/zoo's/mushrooms etc. It seems pointless buying a 250w bulb in a hope that I can wire it up and that the ballast...

that might be my only option, the 400w is virtually brand new though, so it seems pointless buying more stuff that I already have, the 150w is older but I know it works because I used to use it on a previous tank. http://www.marine-lighting.co.uk/ ... you can definitely get them, but as I...

ok, thanks for the replies, ... Melosu58, sorry for double posting, the problem is that I have the all the parts to build either a 400w or even a 150w, but I only have an untested ballast without ignitors or anything to build a 250w (which would be Ideal), and I don't want to spend £60 on a...

after the height of the cabinet and tank the halide would probably have to be on the ceiling, which isn't really an option :? ..... although I do have an old Arcadia 250w unit (although it doesn't have an igniter so I have no way of testing it), If I were to replace the 400w ballast with the...

lighting a 20" cube tank? I want to use halide lighting on the 20" cube tank I plan to build, would 400w be too much? I mainly want to keep soft coral and an anemone or 2, although a couple of SPS corals would be great, (If there are any SPS corals that would get by without added calcium?), or...

makes sense, thanks for clarifying that for me.

If you have some money to spend you could get a UV sterilizer, It's not a guaranteed way of getting rid of Ich but about 3-4 weeks ago I added a copper banded butterfly to my tank and didn't realize it had ich until too late, I bought an 18w UV and I haven't seen any of my fish with ich since.

let me point out that I do not have an algae problem, in fact my current tank is the only one that hasn't had one, can I just ask why it is recommended that you do lots of PWC's to fix an algae problem? surely this is just going to replenish whatever it is that is feeding it, wouldn't it be...

thanks, that's good to know, I'm worried about making a mess of the silicone and ruining the glass.

I was wondering if anyone has tried fixing glass together with aquarium grade silicone to build a tank, I know it can be done but I was wondering how difficult it is, only I'm not happy with the 15" height of my current tank, I was thinking of building a 20" cube tank (20x20x22H) as I can get...

Thanks for the nice comments everyone, :) - It's not live rock, it's actually dead lava rock, I chose it because it's darker than ocean rock so it develops a nice purple colour under actinic lighting. (i'm just hoping it wont mess with the PH or anything too much). - Iv'e since added...

thought I would add a couple of pics of my tank, let me know what you think, please add any suggestions. :)

Ok, thanks. I got the stuff i need to set it up today and added some shrimps after seting it up, now just need it to cycle, I'll post some pics if I get a chance. I'll wait a while anyway before getting coral, but an upgrade would probably be best. stocking wise, I was thinking dwarf lions...

haven't posted here for a while, but after spending alot of money on halides, LR, etc. for my 85 gallon only to have the tank wiped out by ich from a powder blue, I gave up for a while and sold everything. I have decided to give it another go with an empty 45 gallon tank, but I'm looking to...

okay, would this work; JBL Proflora CO2 Set Vario 500, either set 1 or 2; http://www.aquatics-online.co.uk/Z079204.asp .. if so how long would a 500gm bottle last for before needing to be refilled? also, to take the confusion out of the fertilizers can I use something like Seachem...

ok cool, as I said, I can afford to buy a pressurised system but it is all somewhat confusing, what exactly would I need? a cylinder and a regulator, what do I use to put the Co2 in the tank, also what size cylinder would be needed for an 85? what else do I need, root tabs & ferts? also If I...

wow, this plant stuff is confusing ... that Greg Watson stuff is probably great, but being in the UK it is probably not available to me, anyway, I'll probably be able to get the seachem ferts ... or find some equivalent dry ferts. about the CO2, although I do not mind spending the money on a...

I have just stripped down my 85 gallon marine reef to house my discus, I would like to try planting the tank, I understand I need fertilizer ... can anyone tell me which fertilizer to use and when etc. My lighting shouldn't be a problem for many plants (2x 150 watt halides), would I need to...
