Water Changes & Big Rock's

  • We are currently upgrading MFK. thanks! -neo
Hi everyone!!! I was wondering for anyone that has a lot of rock's in their tank's do you remove them every time you do water change's and clean real good underneath? I remove mine every other week.
How big are the rocks? Be careful you don't break the glass.
 
I never move mine, all of them are placed directly on the glass ( flat bottomed boulders. with substrate added after. ) Some are 30-40 pounds a piece, so a little tricky/risky moving around on a regular basis.
i want a pic of your tanks with 15Kg stones in it!
i never move my rocks either

2 of them weigh about 30 lbs. each. I have them on egg crate's. I have my Mom help me. She stands there while I hand them to her and when IM ready she hands them back to me.
 
I stack rock in 2 to 3 piles to make caves with open space in between. I move the rock around to clean tHe bottom trapped distritis one pile at a time in my weekly WC and rotate to another pile next time. Since I pile rock, safety from falling is critical so I use only light larva rock, lace rock, and carved rainbow rock. Carved rock is unnatural, but can lighten up the weight and make good caves. I much prefer the rock to trap some waste so I can siphon up in WC than to overload my HOBs which I am already cleaning twice a week in my heavily stocked tanks.

A trick I find works is to use a smaller siphon hose (like for a micro tank) and push it around the sides and into the substrate around the rock to get the loose stuff. In my display tank I ended up removing most of the smaller rocks (2") because where the sand sloped they kept collecting stuff, plus my fish are growing and making more waste. Since adjusting the powerheads to the surface and taking them out I reduced the maintenace about 20 percent.
 
The bigger rocks are on the bottom of the tank. Casper keeps them free of sand so I dont move them. The small palm sized ones I do move and put back after cleaning. With his digging shenanigans I always have a pits here or there that will collect the detritus (poop). With my water changes every three days they get cleaned out (the pits) before it makes it's way into the filters.

I posted a photo of a past tank in this recent thread. I believe the total weight was 220 pounds.

Being an all male set up this tank evolved & changed over the years as trouble makers got shifted elsewhere, but this is what the tank looked like early on. There was over 200 lbs of granite boulders in there. I no longer have that set up, or those fish, but I still have some of the rocks in tanks.

Big boulders with flat bottom don’t trap waste, so cleaning is not necessary. Though they provide sight barriers and aesthetic value, they don’t provide much cave habitat. There is a style of Japanese aquascaping called iwagumi that focus on rock arrangement with design guideline.


Curved rock such as lace rock, larva rock or carved rainbow rock make good cave habitat, but also trap waste efficiently that need to be cleaned periodically. Carved rock is never used in Iwagumi because they are unnatual. I stack smaller rock on top of bigger rock for safety and easy removal during cleaning. The caves provide good nesting site for Tanganyikan and small CA/SA egg layers which had successfully raised young in my set up amid large open water Haps and CA/SA. In fact, I had to evict entire colonies of Julie’s and Daffodil because they took over the rock piles. Mouth brooders had no success in such set up as parents don’t provide protection of youngs.
