"Rocky" issues

Recommended Posts


Hello everyone!

So recently i got down to scape my 2nd tank. This time for hardscape i decided i was going to use rocks instead of driftwood.

As i had already a small inventory of rocks of different kinds from too many trips to the fish store(hands up people), i could not decide which ones to use! 

I learnt a lesson in the end to just stick with what you know to be safe and inert. Especially if the intended livestock for the tank are soft water lovers. 

Because the local fish stores that i patronize do not have correct labels of the rocks they sell, i had to experiment and research on them as much as i could. 

Most of the rocks look so similar and matching them to pictures on the internet proved to be more frustrating. 

So to use or not to use? Rule of thumb, if you are not too sure, dunk the rocks intended to use in a pail of water and test its ph, if it changes, dont use that. The vinegar test is a hit or miss.

I got too carried away looking at the beautiful scapes from ADA and went out to buy the same light grey coloured rocks only to find out that they can alter the ph by a ton. A fish store owner told me to ask for an exchange of those seiryu rocks i purchased from another store as he said his friend had the ph climbed to 9.4 in his 10gallon, just half a day with just one of that rock. 

Got my exchange thankfully but store ower was very displeased to do that:(

Light grey being either seiryu or sekyri rock, till now i cant be sure.
Reddish coloured rock is dragon stone. (Safer option)aeaeb81393562a7592674c77bfb8b7f6.jpg3524bf6aecf55258a3a1bf096f7dc2ee.jpg

      I live in Hong Kong, there are a few shop in hong kong where you can catch your own shrimp, and this it one of them, this is also one of the cheapest shop. in Hong Kong you can buy almost any shrimps I friend told me about this shop, but this if the first time their.   I'm still deciding what plant to use , my be Fissidens fontanus, those Madagascar lace in the tank are just the leaves, I cut them from the old tank, they have overgrown the tank. but they have good biofilm and bacteria.

      More great photos, good to see the shadow panda, hope they are all doing well? You get such fantastic colour ones where you are! I did my reset tank today and removed lots of plants so it looks a little sparse. Anyway, I will check the ammonia/nitrite/nitrate tomorrow. TDS is 125 so spot on what I predicted using my spreadsheet. There were a lot of unhealthy plants! If the nitrates have dropped I may get a couple of new plants, and maybe even some shrimps next week??? Fingers crossed............. Simon
