KZN stint

Posted: August 9th, 2010, 12:37am CDT by RegLaw

I would like to visit KZN again, because this time I would like to collect Ch. Brownburnii and Ch. Kleinii. On my previous visits (Umdloti, Park Raynie, The Bluff), I have not seen any of these. Can anybody help with a snorkeling site / sites where I will be guaranteed catches of these? I would also appreciate a contact number (for detailed info' perhaps not covered in a reply) of whoever is able to help.
I believe that this is still the better time (seasonally) for KZN.
Thanks a lot.

Methylene Blue

Posted: August 9th, 2010, 11:24pm CDT by MistaOrange

When I use to keep freshwater tropical fish I use to use Methylene Blue to prevent illness & other infections in a QT before introducing them to the DT. I always had a good survival rate using Methylene Blue &I was wondering could I use Methylene Blue for marine fish & inverts in a QT before introducing then to other LS in the DT?

Hi Guys,

I have 3 x 1500x850 (32mm) pieces of glass I want to sell.
I bought it originally for windows for my 75 000lt aquarium I was building.

I abandoned the project when I realised how much my electricity was going to cost.
Please Check my photos for pics when I was testing my system with 10mm glass.

Will see tomorrow morning.

Thanks!

A general question.If I have a mixed fish only system,can I treat it as a reef tank with LR,DSB and macro algae in the sump with no mechanical media.My overflow is plumbed into a large external skimmer.How does the the LR and other critters get food if there is no coral feeding going on.Do I have to have all this for fish only?
old tank syndrome

Posted: August 9th, 2010, 8:57pm CDT by vatso

Hi guys

I have heard of this what is it & what causes it?
Effective small herbivores?

Posted: August 9th, 2010, 8:19pm CDT by Mudshark

Having tried all of the usual measures, I still have red fluffy algae in my 250 litre system. I don't have any tangs in such a small tank obviously. Are there any fish that I could try?

Hermit from hell ...

Posted: August 9th, 2010, 6:47pm CDT by ZeroCool

Hi guys ... i have a hermit from hell ... if i buy another hermit, this one just goes for him, i think i have about 10 empty shells in my tank, and only another small living one ...

I bought another one today, and guess what, the big one from hell went to the new one instantly ...

I had a few damsels in the past, and this hermit are like damsels ... pure bullies !

what can i do ?
Is night light a big requirement ?

Posted: August 9th, 2010, 1:43pm CDT by ZeroCool

Afternoon everyone, i want to know, how important are night light for any marine system ?

I know it is nice to simulate nature ... and that is our ultimate goal.

I had some terrible power surges over the weekend, and my Buyo TL550's LED lights blew. I unscrewed the top unit, replacing the damaged parts, but i want to know, if i put a bulb in, that is totally blue, that will work right ? and ofcourse, it will work on the night switch.

Input please.
My cube to be

Posted: August 9th, 2010, 12:54pm CDT by dean

Hey all. Ive been in the hobby for about 2 years now and im loving it!! Ive been on the forum for a while but i dont post often.[IMG]http://***********************/forum/images/smilies/sorry.gif[/IMG] I just read everything on the forum and would like to thank everyone on here for making it so usefull and interesting.

Ive decided that im going to go for a sps dominated cube. As im a student i dont have alot of $$$ to go for a automated system with a calcium reactor and the works, ill be manually dosing calcium and keep my alk in check.. I know that this takes more of a reefers time to manually dose a system but like i said im a student and have loads of time to do just that.[IMG]http://***********************/forum/images/smilies/tongue_smilie.gif[/IMG]

My system will be 800 by 800 by 650 which will bring the water level to 600. This gives me a total volume of 384 litres. Im going to make my stand a little bit higher than a normal stand as im a tallish chap and dont like bending to see my little critters doing their thing. Ill have black silicon and a rimless design.
As for lighting im contemplating going for a 250 watt 20 000k MH suspended over the tank. I dont want to supplement it with T5s as I think this will be good enough???
As for the filtration, im going to use my current TS2 and im going to transfer my ATS over to the new tank. Ive got loads of live rock and about 15 SPS frags waiting for the new tank.
Im going to order the tank in a couple of days and the MH unit as well. (Frans will come to you during the week)

What i want to know from you knowledgeable folks here on the forum is do you think the light will be adequate enough for SPS corals and if you have any other suggestions???

Thanks so much.
Dean
Ps ill post pictures as soon as the new tank and goodies arrive as i know you are pic mad[IMG]http://***********************/forum/images/smilies/LMFAO.gif[/IMG]

Playing with PAR reader.

Posted: August 9th, 2010, 10:03am CDT by RiaanP

First thanks to Louis and Adriaan at Idol Marine to allow me to play in their workshop.
I took my light units to test with their PAR reader. This unit from AquaMedic. Also a old school single reflector 4 tube unit I got.
Reeftek tubes are Actinic and 12000K white.
All readings taken 100mm away from tube. (pretend it is at water surface)
Reeftek tubes are 3 weeks old and also used 6 months old AquaMedic tubes.

I took my 3 week old Reeftek Tubes.

First test. Reeftec in old light unit.
Actinic 130
White 135
(Tested with 2 actinic on then thereafter with 2 whites on. I think I got reading from the globe below and some from the other tube. Should have shielded the other one)

Same tubes in Aquamedic unit as above.
Actinic 120
White 140

Conclusion. Not a lot different in using a single reflector per tube, or a combined reflector. :whistling:

Test 2.
Ok, what about no reflectors. So I removed the reflectors from the AquaMedic unit
Actinic 53
White 63.

Conclusion
Damn, I lost more than 50% light efficiency. So reflectors is a must. point proven.

Test 3.
So what about my 6 month old Aquamedic light tubes. Put them in the unit with reflectors.
Actinic 330
White 340

Conclusion.
Wow, old Actinic tubes are better than 3 week old Reeftek. Is that possible? Did I mess up somewhere?

So to Test 4.
Thank you Louis who lent me 2 brand new tubes. Both Actinic.
Reeftek 200
AquaMedic 333

Conclusion.
Cheaper does not work?

Then Test 5.
What do both these brand new units do without reflectors,
Reeftek 89
Aquamedic 128

Conclusion.
You need reflectors!!!!

And test 6. Just for fun.
150W mh 1976
Off the scale....
But take into account that a MH give a concentrated spot, where T5 gives can light the tank from side to side. And 200mm to the left or right and the MH reading drop drastically.
thank you
