TM Posted August 10, 2006 Report Share Posted August 10, 2006 It can happen in rocks also, some authors advocate changing 10% to 20% of the rock annually to avoid this, once the tank gets into it's third or 4th year. But hey, that article was scary enough to make me stay with my BB ! Although I guess even a sand bed can be changed if it is suspected of causing something like that! Thats funny how can rock get to old... Its like people that say there gravel is to old and needs to be changed. After the rock has been in for a while you could cook it, cheaper than getting new stuff that could still have a heap of rubbish in. Link to comment Share on other sites More sharing options...
JDM Posted August 10, 2006 Report Share Posted August 10, 2006 [After the rock has been in for a while you could cook it, cheaper than getting new stuff that could still have a heap of rubbish in. ive seen this term "cook it" before, how do you cook rocks? not that im going to do it but it would be handy to know just in case i need to in the future, the rock would then need to be re cycled?

jetskisteve Posted August 10, 2006 Report Share Posted August 10, 2006 Or run Zeovit the rock in my current tank is 14+ years in tanks so imagine in the early days the tech we were using my tank now has a very low PO4 reading (Hanna) I know I know my tanks about to crash :-?

And no you don't have to re-cycle your rock as it stays in salt water Link to comment Share on other sites More sharing options...
wasp Posted August 10, 2006 Report Share Posted August 10, 2006 HI, i think the cause of the high nitrates is from the old hang on filter when i took it off to put my new protein skimmer on i found it had a whole lot of old filter wool that must of been there for years at the bottom for the filter. so i think ill just keep doing water changes until levels come down to a normal range.Dan Good one, that could definately be causing your problems, let's know how it goes . Thats funny how can rock get to old... Its like people that say there gravel is to old and needs to be changed.After the rock has been in for a while you could cook it, cheaper than getting new stuff that could still have a heap of rubbish in. It gets "old" by the pores getting blocked over time by dead bacteria. This may be fixed by cooking it, or chucking it in a rock pool at the beach for a few months, as I have done, comes back sweet. In the throw away USA, the normal practise is to chuck old rock. Also, as stated by others, Zeovit, or for that matter any system that keeps nutrients low, will help by stopping the rock and sand getting klutzed up in the first place.

lduncan Posted August 10, 2006 Report Share Posted August 10, 2006 It gets "old" by the pores getting blocked over time by dead bacteria. It gets "old" by having it sitting in a dirty tank. If the tank is clean and stays clean, the rock will be clean and stay clean. Link to comment Share on other sites More sharing options...

Are you saying that this statement is incorrect? It gets "old" by the pores getting blocked over time by dead bacteria. Or are you just repeating the obvious, that I already said here? Also, as stated by others, Zeovit, or for that matter any system that keeps nutrients low, will help by stopping the rock and sand getting klutzed up in the first place.

lduncan Posted August 10, 2006 Report Share Posted August 10, 2006 The rock doesn't get old because of dead bacteria blocking the pores. Link to comment Share on other sites More sharing options...
wasp Posted August 10, 2006 Report Share Posted August 10, 2006 I didn't even say "because", you misquoted me yet again. And you're splitting hairs again Layton. Link to comment Share on other sites More sharing options...

wasp Posted August 10, 2006 Report Share Posted August 10, 2006 Interesting you say what I said is "just crap". Bomber told me the pores in rock can get blocked by dead bacteria. I thought - Bomber said it, it must be true right? Actually, I think it is true. Link to comment Share on other sites More sharing options...
