Fires all around...

Posted: September 6th, 2011, 1:59am CDT by Dlaria

There are quite a few fires around our area. If we have to evacuate, we'll have to cut off the power, before we go. :(

Is there anything I can do to help the fish while we're gone, if we have to go? I don't have a battery backup.

Tree Looking coral

Posted: September 6th, 2011, 8:20pm CDT by mytank

So I am looking to add some sort of tree looking coral to my tank in the background.

The will be positioned left and right of the tank which means on the left they will be AROUND (not directly infront) of the flow pump and on the right they will be AROUND not in front of the return.

I would like something with a lot of branches and pref colorful too. Kenya are well.... BROWN....

Anyone got some idea's. As for light they will be getting full light from the MH and T5's for 7 hours a day.

Thank you

Power outages

Posted: September 6th, 2011, 4:25pm CDT by George

Power outages, a real scurge to the aquarist. if you are lucky enough to already own a TUNZE electronic pump all you need is a 6105.500 safety connector (R 420.00) & a small 12 volt gate battery
(R 150.00-R170.00) at any gate shop or hobby shop. You can also add a charger which then recharges the battery when power comes on again.(220.00) A1 Radio

The saftey connector will circulate 1 electronic pump for a few hours or power an 1070.05 silence return pump for a few hours. you wont even see that it has come on it is an instant change on and off.

No more dead stuff
Just another example as to why TUNZE is superior

Whats best to use in a canister fiter?

Posted: September 6th, 2011, 1:42pm CDT by 2time

I just cleaned my canister filter that I used on my FW tank and want to hook it up to my tank(SW). What would be best to use in it?

At the moment was thinking of putting in carbon and some filter floss and the filter pad that came with it? What else should I put it?

Thanks
RO membranes and filter cartriges

Posted: September 6th, 2011, 1:28pm CDT by mupwi

Hi all.
I am trying to figure out if I should get a ro unit. From a convenience standpoint I think definitely yes, but not sure from a cost standpoint. My main concern is cartridge replacement. How often should they be replaced? Is it at a certain no of liters or at a certain time interval like every year? I only use about 20l per week so it wont be working too hard as the smallest units seem to be 50gpd.

Polystyrene VS Closed Cell Foam

Posted: September 6th, 2011, 12:00pm CDT by RiaanP
Which one is better?

I'm using closed cell foam (Polyethylene) on my setup. I prefer the black strip under the tank instead of the white polystyrene.

But which one is better. I know polystyrene is available in different hardness levels.

Which one does have the better properties
1. What is the weight limit that each type can support.
2. Do they build up memory?
3. Do they collapse eventually?
4. Water retention, including mildew resistant, rot resistant and will not discolour.
I know the closed cell foam cuts easier and neater than the polystyrene. And it does not break or give that little bits off. And kids cannot discover that they can stick their fingers into the support.

Any comments.

Water changes change the parameters

Posted: September 6th, 2011, 10:36am CDT by Tremayn

Hey reefers. I wanted to run this by. I keep my alk at around 9 (trying to keep it as stable as possible) .. Ca Im still getting up (at 380 last I checked) .. Now I have red sea coral pro salt, it has an Alk of 12 and Ca of 450. If I do a water change then thats going to mess with my parameters. Should I increase my alk to say ...11? That way a water change wont have much of an effect on my parameters.

Also, I would like to know what are the alk, ca and mg of the normal seachem reef salt? I want to change to that when my red sea is finished :)
Thanks kids :)
Snowflake vs honeycomb moray?

Posted: September 6th, 2011, 10:25am CDT by danimal

Hey guys

So I'm thinking about getting a small eel, trying to do as much research as possible before going ahead.

First off - there are plenty of both species near Durban - are there any restrictions on catching them? (i've got the standard marine collecting license)

Secondly - what advice can you give? Which one is a better candidate? I know they are both escape artists, and can give your filtration quite a klap. Also that crustacenas and shrimps can and will be preyed upon, there are stories that if they are kept well fed this is not much of an issue.

A question I have is that when diving I often see caves shared by coral banded shrimp and morays - why is this, if they are its natural prey?

Anyway, any thoughts/advice would be appreciated.

Cheers
Dan

Some photos of critters in my DSBs....

Some kind of worm the mud bed.

Bristle worm

Another worm. There are many different species in your DSB.

Copepod

Bubbles making their way up through the DSB. It could be either oxygen or nitrogen. At first I thought nitrogen, but then realised that it wasn't a totally anaerobic zone, as there is algae growing up against the glass. Any thoughts?

More worm action:)

Hybrid fish? climate change byproduct or rare anomaly

Posted: September 6th, 2011, 8:34am CDT by leslie hempel

guys we are seeing more and more hybrid/ cross bred fish harvested from the wild these days, have they always occurred and are just being brought to our attention now because they are classed as rare and expensive fish or are they becoming more frequent as a result of climate change?

EG: species traveling out of their terratories due to ocean current and temperature changes and now mating with other simular species/

i know Centropyge shepardi i has always been around and a hybrid of a coral beauty and a rusty angel. (i stand to correction @Yuri) but we are seeing more and more trade of unusual fish

what is the reason?

Posted: September 6th, 2011, 8:10am CDT by madmike

Hi all i was wondering if its ok to leave the LED lights on the whole night or does it bother the fish? and how long can you keep RO water and salt water for in a container?
