Carbon will polish the water, making it cleaner looking and removing any yellowing, especially caused by Calurpa. It will also remove many of the poisons that cause corals to retard other corals growth. Fay has problems with her Anemones bleeching which she thinks 'may' be a result of too much carbon. There are stories about people using too much carbon who have had SPS bleech. Use a little at a time, change it often. Most people i've met run carbon and reccomend its use. Pies

40% off list is trade, MICO give me trade. I will be in to see Peter this week too, pickup my new sump Pie

Sorry yes, Pet World (Eddie). Pies

I paid $29ea for my clowns from Pet Plant in CHCH last year. Pies

I have photos of a fast growing Acro, it started to encrust over the aqua-kneedit base on day 4. Pie

Radium Radium are very popular bulbs for marine/reefs. They also sell NARVA and numerous other bulbs. All of halides over my tank came from Radium North Shore. Plumbing: All plumbing available it Mico Plumbing and Piplines. The only place I know of that sells everything you could need. Pie

Dremal worked for me.

I get 40% off at Mico

Am I the only one who found that funny? hehehehhee Ira

Anthony, I told you were to get plumbing from. No carters don't sell everything you need (they may sell some stuff I don't know). Pie

/me has more respect for those little bubbles than he did 15 mintues earlier. Pie

How could a little bubble hurt a ceramic impellor? I found with my sump if the baffels are too close together that the microbubbles just get sucked around and down anyway. Would depend on the amount of flow as well. My new sump has 20cm between baffels. So I can clean it if nessessary, put socks of goodness etc. RnB, you can use icecream containers etc to 'baffle' the initital flow to stop the splash into the sump to begin with. Pieman

Just take out water, never wanting to disturb my sandbed. Pie

Again come around. I did my first one with a drill press and a dremal, worked fine (Thats on the sump downstairs). I got it laser cut because I was lazy, doing it by hand with a drill and a dremal or even jigsaw will save you $80. Pie

RnB - I dump a cup a month-ish. You can't over kalk the water (it has a saturation point). Just make sure your not taking the water from too close to the bottom of the stirer. Pie

You can tell if the bubbles can be fixed by larger sump/baffels. Are the microbubbles being drawn into the sump (i.e visible in the sump)? If yes, bubbles are comming from water being dumped into the sump or from the skimmer. If not its either a air leak or cavitation. Chimera - You probably don't get a cavitation because of the head pressure you pump is under, that is its not able to push water faster than its drawing it in. Cavitation becomes more common the bigger the pump and/or the less head heigh the pump is under. Microbubbles are annoying. Pie

It can be caused by cavitation, this is the problem I have. Simply put, my pump pushes more water than it sucks. Check your plumbing, make sure the pipe feeding the pump is larger than the pipe leaving the pump. Or use a tap to reduce the flow out of the pump until the water clears. Pie

All our shops sell Arcadia, none sell or can supply end caps though. I'd be interested in the prices, as have looked for them myself in the past. Pie

BK - I hope your wrong. Interest rates are rising at the moment, but there is no evidence of house property falling. Definatly slowing down though. I can't invisage house property falling, many people want it to, but I think in reality it won't happen. I certainly hope it does't. So to offer completelty different advice to BK, I would say the sooner you buy the better of you will be. At least this is how owning homes has worked out for me. Piezola

No experance with the OM myself, the people who have purchased them appear to be very happy with them. I have sea swirls, and they come highly reccomended, I give them 10/10. That being said, if its a choice between the 2, and you decide the OM is something you want, I would choose this first. If you look at Chimeras tank/sump thread you will see how hard it is to retrofit the OM. The sea swirl can be added in a snap, much easier to setup. So if you get the OM first, and decide later that you want a Sea Swirl, you can add it afterwards, very hard to do it the other way around. Pie

Its not faulty, it just makes a bit of noise, the whurr is just a whurrr but its noisy, particualry compared to the Ehiems. Would you have your Iwaki in your lounge? I find the 1262s so distracting I turn them off during the time when I am in the house. My 100 does sound like a small motorbike Just messing with you with the ROI thing, as its not a term i've ever heard when considering equipment purchase for the fish tank, as ultimatly the ROI is probably 0 (or less than 0 if you choose to be picky). SteveA - I would tell me I told you so Seriously though, if I thought there was even a miniscule chance of a hole leaking I would't have put 7 through my tank, but I know there isn't. They are glued on both sides, thats 1 extra side over the glass itself I don't think the risk is any more than theoretical. Swiss cheese the tank! Pie

So how did you calculate the ROI? I would have thought that 2 Sea Swirls would have been better than 1. You have more options than you mentioned, like buy a larger return pump and T of the Sea Swirls (like I have), or have 1 of the 2 sea swirls on a closed loop. 2 Sea Swirls dump the Seios. Or use the Seios for under the rock and dump the OM. More current = good. In some ways I wish I had used 3-4 Sea Swirls and not used my streams. The sweeping current seems to stimulate the coral better than just the big pulsing current in one direction. Sure you get intersecting currents but thats very turbid, no soft gentle flow. My IWAKI 30 is much noiser than my Eihem 1262s. I wouldn't want it in my lounge or dining room. Pies

Why? The same silicone thats used to bung the hole is used to hold the tank together. A fear of drilling a tank is an old skool paranoia, its common practice and i've read or seen little about people having problems. The benifits greatly outweigh the risks. Pies

Really, how did you calculate the ROI? I would reccomend the Sea Swirl. Who not drop the SEIOs and just drill the sides, use a SCWD and a pump, one on each side? Or angled through the bottom aiming up and back with a 45? Only thing to beware of is the IWAKI are quite noisey, not all of us have the closed loop pumping in another room Drill the crap out of the tank and dump as many of the in tank pumps as possible. Pie

I use my RXT for a return pump on my 740, water ROCKETS out of it. Only about 3 foot head. Pie
