Yea, this setup will be considered for the feature, I am keeping it fw rn but in 5 months I might go reefing, i am thinking of removing all the gravel then putting sand and live rock, so what sand and rock should I use???Ok, is there fish in there too? Will need to re home those.
Drain and clean tank with vinegar. Clean and soak your filter with vinegar too. Tank is Ready to go reefing!
As mentioned, will need Rock that is suitable for a reef. Live or dry. Live is better.
Do you want sand? Freshwater gravel is not advisable.
