Re: Found a crab in my tank? #1
Its hard to get a pic as it seems to be very shy, baring in mind that the tank has been up and running for a month and i've only seen it on the day i sent the post!!!


It has a relatively large arm and claw which is white and red/brown but seems to be evenly striped rather than red with a little white like a halloween hermit.

Found a crab in my tank? #2
About a month ago, set up a marine tank.

Bought a load of liverock, bought 4 hermit crabs, 3 blue leg and 1 red. 2 clown fish.


Was just staring into the tank and i spotted a claw grabbing at algae on the rocks...............larger than any of the crabs that i bought and a totally different colour. The crab seems to have made a hole in the rock its home.

well, i'm assuming its a crab as it has a big arms with a claw.

any ideas?

Re: Phosphate Absorber - what's best? #3
to be honest, i'm not sure where i'd put it as i have a red sea max 130d, i could put it in a bag next to the carbon media which is below the pumps but i was also considering a fluid?

red sea produce

RED SEA NO3 - PO4 -

XNO3:PO4-X will prevent the growth of nuisance algae and promote coral coloration. N:P-X is a fully researched and tested biochemical product containing a mineral complex and special blend of carbon sources to ensure the long term stability of the treatment as well as inhibiting sulphate reducing bacteria.

any thoughts?

Phosphate Absorber - what's best? #4
Hi there,

got a new marine tank on the go, seem to have a lot of algae growing in there and very quickly too.

i have some hermits and they seem to love munching it but i'd rather it wasn't there to start with as its almost carpeting the sand and really growing on the glass.

my water tests are showing that my phosphate level is high so i'm wondering what is the best option in terms of phosphate absorber??

i've search on the net and only found very little. advice would be greatly appreciated.

Re: Water testing??? #5
Just completed a water test and i'd just like to see what you guys think of the results and where you think i'm at (i will be taking a sample to my lfs tomorrow so they can test the water for me too).

KH 40
PH 6.5 - 7
Nitrite 0 - 0.5
Nitrate 20 - 40

Wasn't quite sure which colour i thought the test was closest too with the PH, nitrite and nitrate.


At this point, my tank is being over taken by brown/red algae (which again, i supposedly normal for a new tank) but i'm not told whether i should leave it or whether the clean up crew (when i eventually get them) will deal with this???

Re: Water testing??? #6
i've been following the set up instructions that come with the red sea max, looking various other websites and speaking with 2 guys from 2 separate fish shops.


i've got brown and red algae appearing in the sand and i have purple, green and brown/red algae on the live rock. some was obviously already there.

with regard to starting the cycle, the red sea max comes with a fluid that you add to the water, not to hand so can't remember its name but the guy in my local store said that that is fine to use.........does this do the same thing as your prawn?

with regard to the nitrate testing..........i simply misread and did a nitrate test instead of nitrite.

bought a new test kit today, API 5 in 1 test strips so hopefully these will help me whilst i'm learning the ropes.

Re: Water testing??? #7
Oh ok,

I bought RO from my local store, i can see the beginnings of the brown, red and green algae.

i am using the red sea max marine lab that came with my RSM 130d.

I've been following the support documents on the red sea website which is why i was test for nitrate.

is there an easier test kit to use? rather than feeling like i'm doing gcse chemistry???

Water testing??? #8
Had my tank set up and running for 5 days now and just performed my first nitrate test.................i followed all of the instructions as they were quite simple.

the water in the tube stayed clear???? what the hell does that mean?

i can only assume it means i did the test wrong????

any thoughts.

Re: Buying a Red Sea Max 130D - Advise wanted. Please #9
So............

Water is in,
Some live rock is in,
Live sand is in and settled.

The water is looking nice and clear now and the skimmer seems to be working as it seems to be kinda dirty in the collector cup. Its been about 4 days now so I guess in a few more days i'll be ready to test the water levels.

As yet, i haven't noticed any algae growing on the live rock but what i've read suggests that i should be seeing some by now??? any thoughts on this?

Is there a step that i should be taking that i've missed?

Re: Buying a Red Sea Max 130D - Advise wanted. Please #10
Ok, so i bought a RSM 130D from ebay for ?280 with a few extra bits and bobs. An additional circulation pump and a RO water filter.

I set it up today and filled it with RO that i bought from my LFS and tomorrow, i'm running the temp up and tomorrow i will be buying some sand and the first bits of live rock.

I do have a question though regarding the protein skimmer.

There are 2 forms of adjustment and i'm not sure exactly how it should look when it is working correctly. With various adjustment it either bubble up lots with a lower water level or seems to only bubble a little with higher water level.

Which is correct?

Also, from what i've read on the RSM website, the air valve should be open but this doesn't seem to have any real effect?
