Hello all, I went to our local river and was able to pick out some nice rocks for my new tank setup. In cleaning them, some of the rocks have cracks/holes in them, others look like they have different rock deposits in them that look almost sandy, and other allow small particles to be rubbed off. I can get some pictures tomorrow when it gets light out outside. I have varying colors or reds, whites and blacks that see like they will work well together. In watching videos a lot of people focus on the acid test to see if it will change water hardness. It seems like regardless of the rock type there are three main concerns: 1. The rock can dissolve in your tank increasing the hardness of your tank. I am not too concerned about that one right now. 2. The rock can have copper deposits in them that can kill your invertebrates. It can also have iron too. This can be seen by the green or brown rust on the rock. 3. The mud and little cracks in the rocks can harbor wild flora and fauna that we do not want in our tanks. This can be treated by bleach, boiling rocks, or baking them. Thin or deep cracks look cool but could be hard to get cleaned out. Besides the copper veins being a big issue for my shrimp it does not seem like the others are deal breakers. Is there other thinks I should be considering before I put the rocks in my tank as hardscape? How do you feel about wild caught rocks?
I have this stuff, that i think might be algae, on many of my plants. The main issue is that it holds onto all the grey detritus, or is the collection of it in my tank. The water is super clear, but when i try to clean the stuff, all the much goes everywhere. When i get the muck off, the fuzzy things are almost clear. Is anyone familiar with this?
