Well after all the tank inspecting with the whitespot and all, I've noticed quite a bit of crap (I'm guessing diatoms) on the sand inside the "caves" I guess you'd call it. (See Pic for idea of caves, theres heaps in the way i've set the rocks up)

Since its inside the caves, I cant get my syphon in there. Question is, if I leave it, will it potentially become bad enough to cause a tank crash?

I have been considering reaquascaping with the possibility of having to catch the sick fish, but didn't think i'd need to, but perhaps it may not be such a bad idea? Unless of course, the crap isn't going to be an issue?

Cheers all

so you dont need a ro/di excellent chch water.

your tank wont crash,

cyno means you have nutrients in the tank.

keep the tank clean and dont feed to much frozen foods,

i would do weekly water changes and gravel syphon the substrate

That chch water joke is wearing pretty thin :-?

Yeah I know its excess nutrients etc, I do plan on getting an RO unit after the silly season. Was just concerned it could cause problems down the track

it is not a joke. dont filtering your water will not help.

No tap water is pure and has many nutrients, tds meter will tell you that.

Ok, so how bout another problem, say I decide to reaquascape anyway? It'll stir up crap. AFAIK, it could cause an increase in Nitrates, but is that it or are there other nasties that can be stirred up?

no problems stirring your tank, i do it weekly.

cant see how stirring sand is going to give you nitrates,

do a test. test nitrates before stirring and after, would be interesting.

I've read it somewhere on one of the forums I think. Always thought it was a possibility if theres stuff under the sand decaying?

Might wait til the whitespot has gone then redo it. Fish and inverts will be fine in the tank while i do it?

I've read it somewhere on one of the forums I think. Always thought it was a possibility if theres stuff under the sand decaying?

so what, its part of a ecosystem. will be used by organisms,.

Having a new tank will mean you will still have low amount of bacteria and organisms to use some of the decay etc,

just keep the tank clean and watch what you put in it. you are what you eat

one thing what you could try is.

does some vodka, 1ml per litre,

or leave your tank lights off for 2 days.

still after that you have to solve the underlining problem of nutrients going into your tank or you will get it back.

forgot to mention, dont feed any frozen foods until your tank is mature as they contain too much waste.

only feed the fish once day,

Get a powerhead and blast all the crap out from under the rocks etc and then run some filter wool or something for a few days afterwards. It will help keep the caves clean. Also, dont have sand in places where you can't syphon and/or see. just put sand in the places you see to make it look good, but right in underneath the rocks etc, if you have sand it will just help trap the detritus. So yea, blast it out regularly, and then use some sort of mechanical filtration afterward to 'clean' the water

does some vodka, 1ml per litre

I think you meant 1ml per 100 litre

unless you meant dose it personaly via oral intake

Running filterwool already.

I'm not worried about how it looks, you cant see it unless u've got a torch

Was just worried it would cause problems

ohk, do you change the filterwool regularly? Best to.

So yea, just blast the crap out (you could just grab one of the nano streams and give it a blast) and it should be fine

I think you meant 1ml per 100 litre

yes, my typing.

i got that to begin with i ajusted my pump so its blowing in a different direction and its fine now

Which reminds me. Where is my vodka

Its in your hand where you left it Marco :roll:

Edit, double post

As per Evilknievil, if you have a spare powerhead, hold it with your hand and blow all around in the rocks with it. Quite a surprising amount of crud will come out. Do this shortly before your waterchange and vacuum the sand when you do the waterchange.

IMO you can never vacuum, and stir things up too much. It is not stirring things up for a long time, then doing it after there is a lot of crud built up, that can cause problems.

But your tank looks fine at the moment, nowhere near the crash you mentioned.

Ok i'll get one of the nanostreams under the rocks next WC

Speaking of nanostreams, the holding clip for my 6045 has snapped, and no amount of glueing/repairing seems to fix it for long. Anyone know where I can get replacement ones without having to buy a whole new unit?

Anyone know where I can get replacement

The shop that you got it from should replace it. they might have to order the part in.

it will snap again if you get a new one... its a tunze design-fault- bout half of the people on here have snapped theirs

I have a brittle star that does a good job of eating / shifting / stirring random crud from under the rocks. There are a couple at O at the moment.

two went on wednesday

Ahh I'll ring John when he's in at 10. Wilson, were there any stars left? Damn keen on one or 2 of those
