Ok i will update once I have rescaped it , is a 1000L wave pump good for this 20 or will it be too much for it? I also plan to paint the background.Do i need more rock ?
I don't understand what you mean by that.
no, having rocks sit on the bottom glass will not crack it. at worst they will put surface scratches.
It's a matter of what you want to keep and your filtration. Fish only you don't need tons of rock unless you need more hiding places, in this case it doesn't like like there is a lot of hiding. If you want low light demanding corals they will do nicely there. High light demanding you would need some structure higher in the water column. Also rock aids a great deal in biological filtration.Do i need more rock ?
Tap water is not at all good for SW, it throws nutrients out of wack. FW and SW environments are very different, In SW, you should use RODI or pure distilled water to mix salt and top-off tank. Molting is not always a sign of good health. Even if you use conditioner, its not good.I think it has, been dosing bacteria daily and seeded with rubble, i used tap water , big boy molted
Basically everything your tank needs is in water is in the salt mix, the stuff in tap water (even conditioned) does not make SW creatures healthier, at best it encourages growth of harmful algae, at worst it kills your animals.
you will get algae no matter the tank. if you properly glue and settle rocks you can create stable stacks and caves while leaving space near the walls clear.
doesn't really matter, if you don't like how it looks you can remove it. If you leave it in itll either get eaten or just disintegrate
