Help..........LR

[Hondace]

Hihi,

Advice needed. I was cycling my 2nd tank & this time tried to save cost by buying some cheap LR ($8/kg). Previously, bot Fuji rocks at around $18/kg and the cycling was quick & successful without any dangerous spike in NH4 & NO2. The whole tank was cycled within 3-4 weeks.

However, tis time round – both the NH4 & NO2 had a v huge spike in just 3 days (both near the high end of the scale) even though I was been told they r cured. Also, there’s some white mold/fungus on the LR (just like those u found on the stale bread). Took the rocks up & smelled them, just a little bit smelly otherwise it’s ok.

So, is tis normal and I just got 2 be more patient? Pls reply.........and share ur experience. Thanks.

think it's some die-off from the rocks. did u put in any powerhead to circulate the water?

it ok with it ....be more patient cycle your tank longer .....then change 50% of your tank water.......then it ok already...

i cycle my first marine for like 2 month......using the uncure LR .....

Shouldn't be a problem. I had those $8/kg LR when cycling and the spike came the NH3/4 spike came the 3rd day. In the end, completed my cycling within 4 weeks.

Sit tight and relaz.

Cheers

yes...I have a powerhead to circulate the water.

2 months! this is v long. My 1st tank took about 3 weeks & I added LS after that although I did suffer some causalties - 1 cardinal, 1 clown fish, 1 bi-colour. Since then, it has stablised with 2 cleaner prawns, 3 damsels, 2 clowns & 1 emperor.

lesson learned.......never buy from unreliable source!
